1 Introduction
11 CodeBlocks
ldquoCodeBlocks is a free C++ IDE built to meet the most demanding needs of its usersrdquo [1] Developed bylsquoThe CodeBlocks Teamrsquo CodeBlock is a free open-source [2] and cross-platform IDE which supportsvarious free compilers It is built around plugin framework which allows functionality of CodeBlock tobe extended by installing appropriate plugins Plugins required for compiling and debugging are alreadyprovided by default This manual is prepared after installing and testing CodeBlock on Ubuntu 12041
and Windows 72
12 Simplecpp
Simplecpp is a package used to write and execute turtle based non-graphicgraphic programs Simplecppis a package developed by Prof Abhiram Ranade at IIT Bombay and the book on lsquoAn Introductionto Programming through C++rsquo by Prof Abhiram Ranade uses simplecpp to explain basic program-ming For more information please refer to the Chapter 1 of the book Simplecpp is integrated withCodeBlocks and the simplecpp programs are tested with CodeBlocks on Windows 7 and Ubuntu 1204

4 Working with CodeBlock on Ubuntu
In this section we discuss writing and building three projects First project (hello worldc) is simpleprogram which displays hello world on output The other project (linec) uses graphicsh header file anddisplays a line graphicsh is not supported by gcc which is the default CC++ compiler on UbuntuThe third project (3polycpp) uses simplecpp package and draws three polygons on output We have toinstall some packages include few libgraph libraries during building the project with graphich headerfile
41 Installation of CodeBlocks
Pre-requisite for installing CodeBlock is lsquolibwxgtkrsquo which is available in ubuntu software center Thispackage will be already installed in your system3 It is also advised to install lsquobuild-essentialrsquo packageand update repository list In case the libwxgtk is not installed it can be installed from command lineusing command given in listing 1 [3] CodeBlock is available in Ubuntursquos repository It can be installedusing Ubuntu Software Center or it can also be installed using command line as given in listing 2
1 $ sudo aptminusget i n s t a l l l ibwxgtk2 8minus02 $ sudo aptminusget i n s t a l l bui ldminuse s s e n t i a l3 $ sudo aptminusget update

line 4 Final list of packages that will be installed in your system
When command line prompts for [Yn] enter lsquoyrsquo and press enter When CodeBlock is run for first timeIt asks for default compiler Select the appropriate compiler to proceed further We have used lsquoGNUGCC Compilerrsquo
42 Installation of packages for graphicsh header file
GCC compiler does not support graphicsh conioh windowsh and few other header files that workson Turbo C or Borland C graphicsh header files enables programmer to write simple cc++ graphicsprograms In Ubuntu gcc is default cc++ compiler thus we have to make some settings for gcc tosupport graphics[4] We will start with installing some packages from command line as given in listing 3

1 Introduction
11 CodeBlocks
ldquoCodeBlocks is a free C++ IDE built to meet the most demanding needs of its usersrdquo [1] Developed bylsquoThe CodeBlocks Teamrsquo CodeBlock is a free open-source [2] and cross-platform IDE which supportsvarious free compilers It is built around plugin framework which allows functionality of CodeBlock tobe extended by installing appropriate plugins Plugins required for compiling and debugging are alreadyprovided by default This manual is prepared after installing and testing CodeBlock on Ubuntu 12041
and Windows 72
12 Simplecpp
Simplecpp is a package used to write and execute turtle based non-graphicgraphic programs Simplecppis a package developed by Prof Abhiram Ranade at IIT Bombay and the book on lsquoAn Introductionto Programming through C++rsquo by Prof Abhiram Ranade uses simplecpp to explain basic program-ming For more information please refer to the Chapter 1 of the book Simplecpp is integrated withCodeBlocks and the simplecpp programs are tested with CodeBlocks on Windows 7 and Ubuntu 1204

4 Working with CodeBlock on Ubuntu
In this section we discuss writing and building three projects First project (hello worldc) is simpleprogram which displays hello world on output The other project (linec) uses graphicsh header file anddisplays a line graphicsh is not supported by gcc which is the default CC++ compiler on UbuntuThe third project (3polycpp) uses simplecpp package and draws three polygons on output We have toinstall some packages include few libgraph libraries during building the project with graphich headerfile
41 Installation of CodeBlocks
Pre-requisite for installing CodeBlock is lsquolibwxgtkrsquo which is available in ubuntu software center Thispackage will be already installed in your system3 It is also advised to install lsquobuild-essentialrsquo packageand update repository list In case the libwxgtk is not installed it can be installed from command lineusing command given in listing 1 [3] CodeBlock is available in Ubuntursquos repository It can be installedusing Ubuntu Software Center or it can also be installed using command line as given in listing 2

When command line prompts for [Yn] enter lsquoyrsquo and press enter When CodeBlock is run for first timeIt asks for default compiler Select the appropriate compiler to proceed further We have used lsquoGNUGCC Compilerrsquo
42 Installation of packages for graphicsh header file
GCC compiler does not support graphicsh conioh windowsh and few other header files that workson Turbo C or Borland C graphicsh header files enables programmer to write simple cc++ graphicsprograms In Ubuntu gcc is default cc++ compiler thus we have to make some settings for gcc tosupport graphics[4] We will start with installing some packages from command line as given in listing 3

1 Introduction
11 CodeBlocks
ldquoCodeBlocks is a free C++ IDE built to meet the most demanding needs of its usersrdquo [1] Developed bylsquoThe CodeBlocks Teamrsquo CodeBlock is a free open-source [2] and cross-platform IDE which supportsvarious free compilers It is built around plugin framework which allows functionality of CodeBlock tobe extended by installing appropriate plugins Plugins required for compiling and debugging are alreadyprovided by default This manual is prepared after installing and testing CodeBlock on Ubuntu 12041
and Windows 72
12 Simplecpp
Simplecpp is a package used to write and execute turtle based non-graphicgraphic programs Simplecppis a package developed by Prof Abhiram Ranade at IIT Bombay and the book on lsquoAn Introductionto Programming through C++rsquo by Prof Abhiram Ranade uses simplecpp to explain basic program-ming For more information please refer to the Chapter 1 of the book Simplecpp is integrated withCodeBlocks and the simplecpp programs are tested with CodeBlocks on Windows 7 and Ubuntu 1204

4 Working with CodeBlock on Ubuntu
In this section we discuss writing and building three projects First project (hello worldc) is simpleprogram which displays hello world on output The other project (linec) uses graphicsh header file anddisplays a line graphicsh is not supported by gcc which is the default CC++ compiler on UbuntuThe third project (3polycpp) uses simplecpp package and draws three polygons on output We have toinstall some packages include few libgraph libraries during building the project with graphich headerfile
41 Installation of CodeBlocks
Pre-requisite for installing CodeBlock is lsquolibwxgtkrsquo which is available in ubuntu software center Thispackage will be already installed in your system3 It is also advised to install lsquobuild-essentialrsquo packageand update repository list In case the libwxgtk is not installed it can be installed from command lineusing command given in listing 1 [3] CodeBlock is available in Ubuntursquos repository It can be installedusing Ubuntu Software Center or it can also be installed using command line as given in listing 2

1 Introduction
11 CodeBlocks
ldquoCodeBlocks is a free C++ IDE built to meet the most demanding needs of its usersrdquo [1] Developed bylsquoThe CodeBlocks Teamrsquo CodeBlock is a free open-source [2] and cross-platform IDE which supportsvarious free compilers It is built around plugin framework which allows functionality of CodeBlock tobe extended by installing appropriate plugins Plugins required for compiling and debugging are alreadyprovided by default This manual is prepared after installing and testing CodeBlock on Ubuntu 12041
and Windows 72
12 Simplecpp
Simplecpp is a package used to write and execute turtle based non-graphicgraphic programs Simplecppis a package developed by Prof Abhiram Ranade at IIT Bombay and the book on lsquoAn Introductionto Programming through C++rsquo by Prof Abhiram Ranade uses simplecpp to explain basic program-ming For more information please refer to the Chapter 1 of the book Simplecpp is integrated withCodeBlocks and the simplecpp programs are tested with CodeBlocks on Windows 7 and Ubuntu 1204

4 Working with CodeBlock on Ubuntu
In this section we discuss writing and building three projects First project (hello worldc) is simpleprogram which displays hello world on output The other project (linec) uses graphicsh header file anddisplays a line graphicsh is not supported by gcc which is the default CC++ compiler on UbuntuThe third project (3polycpp) uses simplecpp package and draws three polygons on output We have toinstall some packages include few libgraph libraries during building the project with graphich headerfile
41 Installation of CodeBlocks
Pre-requisite for installing CodeBlock is lsquolibwxgtkrsquo which is available in ubuntu software center Thispackage will be already installed in your system3 It is also advised to install lsquobuild-essentialrsquo packageand update repository list In case the libwxgtk is not installed it can be installed from command lineusing command given in listing 1 [3] CodeBlock is available in Ubuntursquos repository It can be installedusing Ubuntu Software Center or it can also be installed using command line as given in listing 2

When command line prompts for [Yn] enter lsquoyrsquo and press enter When CodeBlock is run for first timeIt asks for default compiler Select the appropriate compiler to proceed further We have used lsquoGNUGCC Compilerrsquo
42 Installation of packages for graphicsh header file
GCC compiler does not support graphicsh conioh windowsh and few other header files that workson Turbo C or Borland C graphicsh header files enables programmer to write simple cc++ graphicsprograms In Ubuntu gcc is default cc++ compiler thus we have to make some settings for gcc tosupport graphics[4] We will start with installing some packages from command line as given in listing 3

1 Introduction
11 CodeBlocks
ldquoCodeBlocks is a free C++ IDE built to meet the most demanding needs of its usersrdquo [1] Developed bylsquoThe CodeBlocks Teamrsquo CodeBlock is a free open-source [2] and cross-platform IDE which supportsvarious free compilers It is built around plugin framework which allows functionality of CodeBlock tobe extended by installing appropriate plugins Plugins required for compiling and debugging are alreadyprovided by default This manual is prepared after installing and testing CodeBlock on Ubuntu 12041
and Windows 72
12 Simplecpp
Simplecpp is a package used to write and execute turtle based non-graphicgraphic programs Simplecppis a package developed by Prof Abhiram Ranade at IIT Bombay and the book on lsquoAn Introductionto Programming through C++rsquo by Prof Abhiram Ranade uses simplecpp to explain basic program-ming For more information please refer to the Chapter 1 of the book Simplecpp is integrated withCodeBlocks and the simplecpp programs are tested with CodeBlocks on Windows 7 and Ubuntu 1204

4 Working with CodeBlock on Ubuntu
In this section we discuss writing and building three projects First project (hello worldc) is simpleprogram which displays hello world on output The other project (linec) uses graphicsh header file anddisplays a line graphicsh is not supported by gcc which is the default CC++ compiler on UbuntuThe third project (3polycpp) uses simplecpp package and draws three polygons on output We have toinstall some packages include few libgraph libraries during building the project with graphich headerfile
41 Installation of CodeBlocks
Pre-requisite for installing CodeBlock is lsquolibwxgtkrsquo which is available in ubuntu software center Thispackage will be already installed in your system3 It is also advised to install lsquobuild-essentialrsquo packageand update repository list In case the libwxgtk is not installed it can be installed from command lineusing command given in listing 1 [3] CodeBlock is available in Ubuntursquos repository It can be installedusing Ubuntu Software Center or it can also be installed using command line as given in listing 2

Figure 71 shows CodeBlock along with itrsquos logo in Ubuntu Software Center while figure 72 showsinstallation of CodeBlock using command line In figure 72 four underlined lines are
line 1 Command to install the CodeBlock
line 2 Packages installed along with CodeBlock
line 3 Packages suggested along with CodeBlock installation libwxgtk284 package as mentioned aboveis already installed in your system libwxgtk28-dev package is not required
line 4 Final list of packages that will be installed in your system
When command line prompts for [Yn] enter lsquoyrsquo and press enter When CodeBlock is run for first timeIt asks for default compiler Select the appropriate compiler to proceed further We have used lsquoGNUGCC Compilerrsquo
42 Installation of packages for graphicsh header file
GCC compiler does not support graphicsh conioh windowsh and few other header files that workson Turbo C or Borland C graphicsh header files enables programmer to write simple cc++ graphicsprograms In Ubuntu gcc is default cc++ compiler thus we have to make some settings for gcc tosupport graphics[4] We will start with installing some packages from command line as given in listing 3

4 Working with CodeBlock on Ubuntu
In this section we discuss writing and building three projects First project (hello worldc) is simpleprogram which displays hello world on output The other project (linec) uses graphicsh header file anddisplays a line graphicsh is not supported by gcc which is the default CC++ compiler on UbuntuThe third project (3polycpp) uses simplecpp package and draws three polygons on output We have toinstall some packages include few libgraph libraries during building the project with graphich headerfile
41 Installation of CodeBlocks
Pre-requisite for installing CodeBlock is lsquolibwxgtkrsquo which is available in ubuntu software center Thispackage will be already installed in your system3 It is also advised to install lsquobuild-essentialrsquo packageand update repository list In case the libwxgtk is not installed it can be installed from command lineusing command given in listing 1 [3] CodeBlock is available in Ubuntursquos repository It can be installedusing Ubuntu Software Center or it can also be installed using command line as given in listing 2
1 $ sudo aptminusget i n s t a l l l ibwxgtk2 8minus02 $ sudo aptminusget i n s t a l l bui ldminuse s s e n t i a l3 $ sudo aptminusget update

4 Working with CodeBlock on Ubuntu
In this section we discuss writing and building three projects First project (hello worldc) is simpleprogram which displays hello world on output The other project (linec) uses graphicsh header file anddisplays a line graphicsh is not supported by gcc which is the default CC++ compiler on UbuntuThe third project (3polycpp) uses simplecpp package and draws three polygons on output We have toinstall some packages include few libgraph libraries during building the project with graphich headerfile
41 Installation of CodeBlocks
Pre-requisite for installing CodeBlock is lsquolibwxgtkrsquo which is available in ubuntu software center Thispackage will be already installed in your system3 It is also advised to install lsquobuild-essentialrsquo packageand update repository list In case the libwxgtk is not installed it can be installed from command lineusing command given in listing 1 [3] CodeBlock is available in Ubuntursquos repository It can be installedusing Ubuntu Software Center or it can also be installed using command line as given in listing 2

4 Working with CodeBlock on Ubuntu
In this section we discuss writing and building three projects First project (hello worldc) is simpleprogram which displays hello world on output The other project (linec) uses graphicsh header file anddisplays a line graphicsh is not supported by gcc which is the default CC++ compiler on UbuntuThe third project (3polycpp) uses simplecpp package and draws three polygons on output We have toinstall some packages include few libgraph libraries during building the project with graphich headerfile
41 Installation of CodeBlocks
Pre-requisite for installing CodeBlock is lsquolibwxgtkrsquo which is available in ubuntu software center Thispackage will be already installed in your system3 It is also advised to install lsquobuild-essentialrsquo packageand update repository list In case the libwxgtk is not installed it can be installed from command lineusing command given in listing 1 [3] CodeBlock is available in Ubuntursquos repository It can be installedusing Ubuntu Software Center or it can also be installed using command line as given in listing 2

4 Working with CodeBlock on Ubuntu
In this section we discuss writing and building three projects First project (hello worldc) is simpleprogram which displays hello world on output The other project (linec) uses graphicsh header file anddisplays a line graphicsh is not supported by gcc which is the default CC++ compiler on UbuntuThe third project (3polycpp) uses simplecpp package and draws three polygons on output We have toinstall some packages include few libgraph libraries during building the project with graphich headerfile
41 Installation of CodeBlocks
Pre-requisite for installing CodeBlock is lsquolibwxgtkrsquo which is available in ubuntu software center Thispackage will be already installed in your system3 It is also advised to install lsquobuild-essentialrsquo packageand update repository list In case the libwxgtk is not installed it can be installed from command lineusing command given in listing 1 [3] CodeBlock is available in Ubuntursquos repository It can be installedusing Ubuntu Software Center or it can also be installed using command line as given in listing 2

4 Working with CodeBlock on Ubuntu
In this section we discuss writing and building three projects First project (hello worldc) is simpleprogram which displays hello world on output The other project (linec) uses graphicsh header file anddisplays a line graphicsh is not supported by gcc which is the default CC++ compiler on UbuntuThe third project (3polycpp) uses simplecpp package and draws three polygons on output We have toinstall some packages include few libgraph libraries during building the project with graphich headerfile
41 Installation of CodeBlocks
Pre-requisite for installing CodeBlock is lsquolibwxgtkrsquo which is available in ubuntu software center Thispackage will be already installed in your system3 It is also advised to install lsquobuild-essentialrsquo packageand update repository list In case the libwxgtk is not installed it can be installed from command lineusing command given in listing 1 [3] CodeBlock is available in Ubuntursquos repository It can be installedusing Ubuntu Software Center or it can also be installed using command line as given in listing 2
1 $ sudo aptminusget i n s t a l l l ibwxgtk2 8minus02 $ sudo aptminusget i n s t a l l bui ldminuse s s e n t i a l3 $ sudo aptminusget update

When command line prompts for [Yn] enter lsquoyrsquo and press enter When CodeBlock is run for first timeIt asks for default compiler Select the appropriate compiler to proceed further We have used lsquoGNUGCC Compilerrsquo
42 Installation of packages for graphicsh header file
GCC compiler does not support graphicsh conioh windowsh and few other header files that workson Turbo C or Borland C graphicsh header files enables programmer to write simple cc++ graphicsprograms In Ubuntu gcc is default cc++ compiler thus we have to make some settings for gcc tosupport graphics[4] We will start with installing some packages from command line as given in listing 3

4 Working with CodeBlock on Ubuntu
In this section we discuss writing and building three projects First project (hello worldc) is simpleprogram which displays hello world on output The other project (linec) uses graphicsh header file anddisplays a line graphicsh is not supported by gcc which is the default CC++ compiler on UbuntuThe third project (3polycpp) uses simplecpp package and draws three polygons on output We have toinstall some packages include few libgraph libraries during building the project with graphich headerfile
41 Installation of CodeBlocks
Pre-requisite for installing CodeBlock is lsquolibwxgtkrsquo which is available in ubuntu software center Thispackage will be already installed in your system3 It is also advised to install lsquobuild-essentialrsquo packageand update repository list In case the libwxgtk is not installed it can be installed from command lineusing command given in listing 1 [3] CodeBlock is available in Ubuntursquos repository It can be installedusing Ubuntu Software Center or it can also be installed using command line as given in listing 2

4 Working with CodeBlock on Ubuntu
In this section we discuss writing and building three projects First project (hello worldc) is simpleprogram which displays hello world on output The other project (linec) uses graphicsh header file anddisplays a line graphicsh is not supported by gcc which is the default CC++ compiler on UbuntuThe third project (3polycpp) uses simplecpp package and draws three polygons on output We have toinstall some packages include few libgraph libraries during building the project with graphich headerfile
41 Installation of CodeBlocks
Pre-requisite for installing CodeBlock is lsquolibwxgtkrsquo which is available in ubuntu software center Thispackage will be already installed in your system3 It is also advised to install lsquobuild-essentialrsquo packageand update repository list In case the libwxgtk is not installed it can be installed from command lineusing command given in listing 1 [3] CodeBlock is available in Ubuntursquos repository It can be installedusing Ubuntu Software Center or it can also be installed using command line as given in listing 2
1 $ sudo aptminusget i n s t a l l l ibwxgtk2 8minus02 $ sudo aptminusget i n s t a l l bui ldminuse s s e n t i a l3 $ sudo aptminusget update

When command line prompts for [Yn] enter lsquoyrsquo and press enter When CodeBlock is run for first timeIt asks for default compiler Select the appropriate compiler to proceed further We have used lsquoGNUGCC Compilerrsquo
42 Installation of packages for graphicsh header file
GCC compiler does not support graphicsh conioh windowsh and few other header files that workson Turbo C or Borland C graphicsh header files enables programmer to write simple cc++ graphicsprograms In Ubuntu gcc is default cc++ compiler thus we have to make some settings for gcc tosupport graphics[4] We will start with installing some packages from command line as given in listing 3

4 Working with CodeBlock on Ubuntu
In this section we discuss writing and building three projects First project (hello worldc) is simpleprogram which displays hello world on output The other project (linec) uses graphicsh header file anddisplays a line graphicsh is not supported by gcc which is the default CC++ compiler on UbuntuThe third project (3polycpp) uses simplecpp package and draws three polygons on output We have toinstall some packages include few libgraph libraries during building the project with graphich headerfile
41 Installation of CodeBlocks
Pre-requisite for installing CodeBlock is lsquolibwxgtkrsquo which is available in ubuntu software center Thispackage will be already installed in your system3 It is also advised to install lsquobuild-essentialrsquo packageand update repository list In case the libwxgtk is not installed it can be installed from command lineusing command given in listing 1 [3] CodeBlock is available in Ubuntursquos repository It can be installedusing Ubuntu Software Center or it can also be installed using command line as given in listing 2

When command line prompts for [Yn] enter lsquoyrsquo and press enter When CodeBlock is run for first timeIt asks for default compiler Select the appropriate compiler to proceed further We have used lsquoGNUGCC Compilerrsquo
42 Installation of packages for graphicsh header file
GCC compiler does not support graphicsh conioh windowsh and few other header files that workson Turbo C or Borland C graphicsh header files enables programmer to write simple cc++ graphicsprograms In Ubuntu gcc is default cc++ compiler thus we have to make some settings for gcc tosupport graphics[4] We will start with installing some packages from command line as given in listing 3

4 Working with CodeBlock on Ubuntu
In this section we discuss writing and building three projects First project (hello worldc) is simpleprogram which displays hello world on output The other project (linec) uses graphicsh header file anddisplays a line graphicsh is not supported by gcc which is the default CC++ compiler on UbuntuThe third project (3polycpp) uses simplecpp package and draws three polygons on output We have toinstall some packages include few libgraph libraries during building the project with graphich headerfile
41 Installation of CodeBlocks
Pre-requisite for installing CodeBlock is lsquolibwxgtkrsquo which is available in ubuntu software center Thispackage will be already installed in your system3 It is also advised to install lsquobuild-essentialrsquo packageand update repository list In case the libwxgtk is not installed it can be installed from command lineusing command given in listing 1 [3] CodeBlock is available in Ubuntursquos repository It can be installedusing Ubuntu Software Center or it can also be installed using command line as given in listing 2

4 Working with CodeBlock on Ubuntu
In this section we discuss writing and building three projects First project (hello worldc) is simpleprogram which displays hello world on output The other project (linec) uses graphicsh header file anddisplays a line graphicsh is not supported by gcc which is the default CC++ compiler on UbuntuThe third project (3polycpp) uses simplecpp package and draws three polygons on output We have toinstall some packages include few libgraph libraries during building the project with graphich headerfile
41 Installation of CodeBlocks
Pre-requisite for installing CodeBlock is lsquolibwxgtkrsquo which is available in ubuntu software center Thispackage will be already installed in your system3 It is also advised to install lsquobuild-essentialrsquo packageand update repository list In case the libwxgtk is not installed it can be installed from command lineusing command given in listing 1 [3] CodeBlock is available in Ubuntursquos repository It can be installedusing Ubuntu Software Center or it can also be installed using command line as given in listing 2

4 Working with CodeBlock on Ubuntu
In this section we discuss writing and building three projects First project (hello worldc) is simpleprogram which displays hello world on output The other project (linec) uses graphicsh header file anddisplays a line graphicsh is not supported by gcc which is the default CC++ compiler on UbuntuThe third project (3polycpp) uses simplecpp package and draws three polygons on output We have toinstall some packages include few libgraph libraries during building the project with graphich headerfile
41 Installation of CodeBlocks
Pre-requisite for installing CodeBlock is lsquolibwxgtkrsquo which is available in ubuntu software center Thispackage will be already installed in your system3 It is also advised to install lsquobuild-essentialrsquo packageand update repository list In case the libwxgtk is not installed it can be installed from command lineusing command given in listing 1 [3] CodeBlock is available in Ubuntursquos repository It can be installedusing Ubuntu Software Center or it can also be installed using command line as given in listing 2

4 Working with CodeBlock on Ubuntu
In this section we discuss writing and building three projects First project (hello worldc) is simpleprogram which displays hello world on output The other project (linec) uses graphicsh header file anddisplays a line graphicsh is not supported by gcc which is the default CC++ compiler on UbuntuThe third project (3polycpp) uses simplecpp package and draws three polygons on output We have toinstall some packages include few libgraph libraries during building the project with graphich headerfile
41 Installation of CodeBlocks
Pre-requisite for installing CodeBlock is lsquolibwxgtkrsquo which is available in ubuntu software center Thispackage will be already installed in your system3 It is also advised to install lsquobuild-essentialrsquo packageand update repository list In case the libwxgtk is not installed it can be installed from command lineusing command given in listing 1 [3] CodeBlock is available in Ubuntursquos repository It can be installedusing Ubuntu Software Center or it can also be installed using command line as given in listing 2
1 $ sudo aptminusget i n s t a l l l ibwxgtk2 8minus02 $ sudo aptminusget i n s t a l l bui ldminuse s s e n t i a l3 $ sudo aptminusget update

line 4 Final list of packages that will be installed in your system
When command line prompts for [Yn] enter lsquoyrsquo and press enter When CodeBlock is run for first timeIt asks for default compiler Select the appropriate compiler to proceed further We have used lsquoGNUGCC Compilerrsquo
42 Installation of packages for graphicsh header file
GCC compiler does not support graphicsh conioh windowsh and few other header files that workson Turbo C or Borland C graphicsh header files enables programmer to write simple cc++ graphicsprograms In Ubuntu gcc is default cc++ compiler thus we have to make some settings for gcc tosupport graphics[4] We will start with installing some packages from command line as given in listing 3
1 $ sudo aptminusget i n s t a l l l i b s d lminusimage1 2 l i b s d lminusimage1 2minusdev gu i l e minus18 gu i l e minus18minusdevl i b s d l 1 2 debian l i b a r t minus20minusdev l i b a u d i o f i l e minusdev l ibe sd0minusdev l i b d i r e c t f b minusdevl i b d i r e c t f b minusext ra l i b f r e e t yp e 6minusdev l ibxextminusdev x11protominusxextminusdev l i b f r e e t y p e 6l i baa1 l ibaa1minusdev l i b s l ang2minusdev l ibasound2 l ibasound2minusdev

4 Working with CodeBlock on Ubuntu
In this section we discuss writing and building three projects First project (hello worldc) is simpleprogram which displays hello world on output The other project (linec) uses graphicsh header file anddisplays a line graphicsh is not supported by gcc which is the default CC++ compiler on UbuntuThe third project (3polycpp) uses simplecpp package and draws three polygons on output We have toinstall some packages include few libgraph libraries during building the project with graphich headerfile
41 Installation of CodeBlocks
Pre-requisite for installing CodeBlock is lsquolibwxgtkrsquo which is available in ubuntu software center Thispackage will be already installed in your system3 It is also advised to install lsquobuild-essentialrsquo packageand update repository list In case the libwxgtk is not installed it can be installed from command lineusing command given in listing 1 [3] CodeBlock is available in Ubuntursquos repository It can be installedusing Ubuntu Software Center or it can also be installed using command line as given in listing 2
1 $ sudo aptminusget i n s t a l l l ibwxgtk2 8minus02 $ sudo aptminusget i n s t a l l bui ldminuse s s e n t i a l3 $ sudo aptminusget update

Figure 71 shows CodeBlock along with itrsquos logo in Ubuntu Software Center while figure 72 showsinstallation of CodeBlock using command line In figure 72 four underlined lines are
line 1 Command to install the CodeBlock
line 2 Packages installed along with CodeBlock
line 3 Packages suggested along with CodeBlock installation libwxgtk284 package as mentioned aboveis already installed in your system libwxgtk28-dev package is not required
line 4 Final list of packages that will be installed in your system
When command line prompts for [Yn] enter lsquoyrsquo and press enter When CodeBlock is run for first timeIt asks for default compiler Select the appropriate compiler to proceed further We have used lsquoGNUGCC Compilerrsquo
42 Installation of packages for graphicsh header file
GCC compiler does not support graphicsh conioh windowsh and few other header files that workson Turbo C or Borland C graphicsh header files enables programmer to write simple cc++ graphicsprograms In Ubuntu gcc is default cc++ compiler thus we have to make some settings for gcc tosupport graphics[4] We will start with installing some packages from command line as given in listing 3
1 $ sudo aptminusget i n s t a l l l i b s d lminusimage1 2 l i b s d lminusimage1 2minusdev gu i l e minus18 gu i l e minus18minusdevl i b s d l 1 2 debian l i b a r t minus20minusdev l i b a u d i o f i l e minusdev l ibe sd0minusdev l i b d i r e c t f b minusdevl i b d i r e c t f b minusext ra l i b f r e e t yp e 6minusdev l ibxextminusdev x11protominusxextminusdev l i b f r e e t y p e 6l i baa1 l ibaa1minusdev l i b s l ang2minusdev l ibasound2 l ibasound2minusdev

4 Working with CodeBlock on Ubuntu
In this section we discuss writing and building three projects First project (hello worldc) is simpleprogram which displays hello world on output The other project (linec) uses graphicsh header file anddisplays a line graphicsh is not supported by gcc which is the default CC++ compiler on UbuntuThe third project (3polycpp) uses simplecpp package and draws three polygons on output We have toinstall some packages include few libgraph libraries during building the project with graphich headerfile
41 Installation of CodeBlocks
Pre-requisite for installing CodeBlock is lsquolibwxgtkrsquo which is available in ubuntu software center Thispackage will be already installed in your system3 It is also advised to install lsquobuild-essentialrsquo packageand update repository list In case the libwxgtk is not installed it can be installed from command lineusing command given in listing 1 [3] CodeBlock is available in Ubuntursquos repository It can be installedusing Ubuntu Software Center or it can also be installed using command line as given in listing 2

4 Working with CodeBlock on Ubuntu
In this section we discuss writing and building three projects First project (hello worldc) is simpleprogram which displays hello world on output The other project (linec) uses graphicsh header file anddisplays a line graphicsh is not supported by gcc which is the default CC++ compiler on UbuntuThe third project (3polycpp) uses simplecpp package and draws three polygons on output We have toinstall some packages include few libgraph libraries during building the project with graphich headerfile
41 Installation of CodeBlocks
Pre-requisite for installing CodeBlock is lsquolibwxgtkrsquo which is available in ubuntu software center Thispackage will be already installed in your system3 It is also advised to install lsquobuild-essentialrsquo packageand update repository list In case the libwxgtk is not installed it can be installed from command lineusing command given in listing 1 [3] CodeBlock is available in Ubuntursquos repository It can be installedusing Ubuntu Software Center or it can also be installed using command line as given in listing 2
1 $ sudo aptminusget i n s t a l l l ibwxgtk2 8minus02 $ sudo aptminusget i n s t a l l bui ldminuse s s e n t i a l3 $ sudo aptminusget update

line 4 Final list of packages that will be installed in your system
When command line prompts for [Yn] enter lsquoyrsquo and press enter When CodeBlock is run for first timeIt asks for default compiler Select the appropriate compiler to proceed further We have used lsquoGNUGCC Compilerrsquo
42 Installation of packages for graphicsh header file
GCC compiler does not support graphicsh conioh windowsh and few other header files that workson Turbo C or Borland C graphicsh header files enables programmer to write simple cc++ graphicsprograms In Ubuntu gcc is default cc++ compiler thus we have to make some settings for gcc tosupport graphics[4] We will start with installing some packages from command line as given in listing 3

4 Working with CodeBlock on Ubuntu
In this section we discuss writing and building three projects First project (hello worldc) is simpleprogram which displays hello world on output The other project (linec) uses graphicsh header file anddisplays a line graphicsh is not supported by gcc which is the default CC++ compiler on UbuntuThe third project (3polycpp) uses simplecpp package and draws three polygons on output We have toinstall some packages include few libgraph libraries during building the project with graphich headerfile
41 Installation of CodeBlocks
Pre-requisite for installing CodeBlock is lsquolibwxgtkrsquo which is available in ubuntu software center Thispackage will be already installed in your system3 It is also advised to install lsquobuild-essentialrsquo packageand update repository list In case the libwxgtk is not installed it can be installed from command lineusing command given in listing 1 [3] CodeBlock is available in Ubuntursquos repository It can be installedusing Ubuntu Software Center or it can also be installed using command line as given in listing 2
1 $ sudo aptminusget i n s t a l l l ibwxgtk2 8minus02 $ sudo aptminusget i n s t a l l bui ldminuse s s e n t i a l3 $ sudo aptminusget update

Figure 71 shows CodeBlock along with itrsquos logo in Ubuntu Software Center while figure 72 showsinstallation of CodeBlock using command line In figure 72 four underlined lines are
line 1 Command to install the CodeBlock
line 2 Packages installed along with CodeBlock
line 3 Packages suggested along with CodeBlock installation libwxgtk284 package as mentioned aboveis already installed in your system libwxgtk28-dev package is not required
line 4 Final list of packages that will be installed in your system
When command line prompts for [Yn] enter lsquoyrsquo and press enter When CodeBlock is run for first timeIt asks for default compiler Select the appropriate compiler to proceed further We have used lsquoGNUGCC Compilerrsquo
42 Installation of packages for graphicsh header file
GCC compiler does not support graphicsh conioh windowsh and few other header files that workson Turbo C or Borland C graphicsh header files enables programmer to write simple cc++ graphicsprograms In Ubuntu gcc is default cc++ compiler thus we have to make some settings for gcc tosupport graphics[4] We will start with installing some packages from command line as given in listing 3
1 $ sudo aptminusget i n s t a l l l i b s d lminusimage1 2 l i b s d lminusimage1 2minusdev gu i l e minus18 gu i l e minus18minusdevl i b s d l 1 2 debian l i b a r t minus20minusdev l i b a u d i o f i l e minusdev l ibe sd0minusdev l i b d i r e c t f b minusdevl i b d i r e c t f b minusext ra l i b f r e e t yp e 6minusdev l ibxextminusdev x11protominusxextminusdev l i b f r e e t y p e 6l i baa1 l ibaa1minusdev l i b s l ang2minusdev l ibasound2 l ibasound2minusdev

4 Working with CodeBlock on Ubuntu
In this section we discuss writing and building three projects First project (hello worldc) is simpleprogram which displays hello world on output The other project (linec) uses graphicsh header file anddisplays a line graphicsh is not supported by gcc which is the default CC++ compiler on UbuntuThe third project (3polycpp) uses simplecpp package and draws three polygons on output We have toinstall some packages include few libgraph libraries during building the project with graphich headerfile
41 Installation of CodeBlocks
Pre-requisite for installing CodeBlock is lsquolibwxgtkrsquo which is available in ubuntu software center Thispackage will be already installed in your system3 It is also advised to install lsquobuild-essentialrsquo packageand update repository list In case the libwxgtk is not installed it can be installed from command lineusing command given in listing 1 [3] CodeBlock is available in Ubuntursquos repository It can be installedusing Ubuntu Software Center or it can also be installed using command line as given in listing 2

4 Working with CodeBlock on Ubuntu
In this section we discuss writing and building three projects First project (hello worldc) is simpleprogram which displays hello world on output The other project (linec) uses graphicsh header file anddisplays a line graphicsh is not supported by gcc which is the default CC++ compiler on UbuntuThe third project (3polycpp) uses simplecpp package and draws three polygons on output We have toinstall some packages include few libgraph libraries during building the project with graphich headerfile
41 Installation of CodeBlocks
Pre-requisite for installing CodeBlock is lsquolibwxgtkrsquo which is available in ubuntu software center Thispackage will be already installed in your system3 It is also advised to install lsquobuild-essentialrsquo packageand update repository list In case the libwxgtk is not installed it can be installed from command lineusing command given in listing 1 [3] CodeBlock is available in Ubuntursquos repository It can be installedusing Ubuntu Software Center or it can also be installed using command line as given in listing 2
1 $ sudo aptminusget i n s t a l l l ibwxgtk2 8minus02 $ sudo aptminusget i n s t a l l bui ldminuse s s e n t i a l3 $ sudo aptminusget update

When command line prompts for [Yn] enter lsquoyrsquo and press enter When CodeBlock is run for first timeIt asks for default compiler Select the appropriate compiler to proceed further We have used lsquoGNUGCC Compilerrsquo
42 Installation of packages for graphicsh header file
GCC compiler does not support graphicsh conioh windowsh and few other header files that workson Turbo C or Borland C graphicsh header files enables programmer to write simple cc++ graphicsprograms In Ubuntu gcc is default cc++ compiler thus we have to make some settings for gcc tosupport graphics[4] We will start with installing some packages from command line as given in listing 3

4 Working with CodeBlock on Ubuntu
In this section we discuss writing and building three projects First project (hello worldc) is simpleprogram which displays hello world on output The other project (linec) uses graphicsh header file anddisplays a line graphicsh is not supported by gcc which is the default CC++ compiler on UbuntuThe third project (3polycpp) uses simplecpp package and draws three polygons on output We have toinstall some packages include few libgraph libraries during building the project with graphich headerfile
41 Installation of CodeBlocks
Pre-requisite for installing CodeBlock is lsquolibwxgtkrsquo which is available in ubuntu software center Thispackage will be already installed in your system3 It is also advised to install lsquobuild-essentialrsquo packageand update repository list In case the libwxgtk is not installed it can be installed from command lineusing command given in listing 1 [3] CodeBlock is available in Ubuntursquos repository It can be installedusing Ubuntu Software Center or it can also be installed using command line as given in listing 2
1 $ sudo aptminusget i n s t a l l l ibwxgtk2 8minus02 $ sudo aptminusget i n s t a l l bui ldminuse s s e n t i a l3 $ sudo aptminusget update

Figure 71 shows CodeBlock along with itrsquos logo in Ubuntu Software Center while figure 72 showsinstallation of CodeBlock using command line In figure 72 four underlined lines are
line 1 Command to install the CodeBlock
line 2 Packages installed along with CodeBlock
line 3 Packages suggested along with CodeBlock installation libwxgtk284 package as mentioned aboveis already installed in your system libwxgtk28-dev package is not required
line 4 Final list of packages that will be installed in your system
When command line prompts for [Yn] enter lsquoyrsquo and press enter When CodeBlock is run for first timeIt asks for default compiler Select the appropriate compiler to proceed further We have used lsquoGNUGCC Compilerrsquo
42 Installation of packages for graphicsh header file
GCC compiler does not support graphicsh conioh windowsh and few other header files that workson Turbo C or Borland C graphicsh header files enables programmer to write simple cc++ graphicsprograms In Ubuntu gcc is default cc++ compiler thus we have to make some settings for gcc tosupport graphics[4] We will start with installing some packages from command line as given in listing 3
1 $ sudo aptminusget i n s t a l l l i b s d lminusimage1 2 l i b s d lminusimage1 2minusdev gu i l e minus18 gu i l e minus18minusdevl i b s d l 1 2 debian l i b a r t minus20minusdev l i b a u d i o f i l e minusdev l ibe sd0minusdev l i b d i r e c t f b minusdevl i b d i r e c t f b minusext ra l i b f r e e t yp e 6minusdev l ibxextminusdev x11protominusxextminusdev l i b f r e e t y p e 6l i baa1 l ibaa1minusdev l i b s l ang2minusdev l ibasound2 l ibasound2minusdev

4 Working with CodeBlock on Ubuntu
In this section we discuss writing and building three projects First project (hello worldc) is simpleprogram which displays hello world on output The other project (linec) uses graphicsh header file anddisplays a line graphicsh is not supported by gcc which is the default CC++ compiler on UbuntuThe third project (3polycpp) uses simplecpp package and draws three polygons on output We have toinstall some packages include few libgraph libraries during building the project with graphich headerfile
41 Installation of CodeBlocks
Pre-requisite for installing CodeBlock is lsquolibwxgtkrsquo which is available in ubuntu software center Thispackage will be already installed in your system3 It is also advised to install lsquobuild-essentialrsquo packageand update repository list In case the libwxgtk is not installed it can be installed from command lineusing command given in listing 1 [3] CodeBlock is available in Ubuntursquos repository It can be installedusing Ubuntu Software Center or it can also be installed using command line as given in listing 2

4 Working with CodeBlock on Ubuntu
In this section we discuss writing and building three projects First project (hello worldc) is simpleprogram which displays hello world on output The other project (linec) uses graphicsh header file anddisplays a line graphicsh is not supported by gcc which is the default CC++ compiler on UbuntuThe third project (3polycpp) uses simplecpp package and draws three polygons on output We have toinstall some packages include few libgraph libraries during building the project with graphich headerfile
41 Installation of CodeBlocks
Pre-requisite for installing CodeBlock is lsquolibwxgtkrsquo which is available in ubuntu software center Thispackage will be already installed in your system3 It is also advised to install lsquobuild-essentialrsquo packageand update repository list In case the libwxgtk is not installed it can be installed from command lineusing command given in listing 1 [3] CodeBlock is available in Ubuntursquos repository It can be installedusing Ubuntu Software Center or it can also be installed using command line as given in listing 2
1 $ sudo aptminusget i n s t a l l l ibwxgtk2 8minus02 $ sudo aptminusget i n s t a l l bui ldminuse s s e n t i a l3 $ sudo aptminusget update

4 Working with CodeBlock on Ubuntu
In this section we discuss writing and building three projects First project (hello worldc) is simpleprogram which displays hello world on output The other project (linec) uses graphicsh header file anddisplays a line graphicsh is not supported by gcc which is the default CC++ compiler on UbuntuThe third project (3polycpp) uses simplecpp package and draws three polygons on output We have toinstall some packages include few libgraph libraries during building the project with graphich headerfile
41 Installation of CodeBlocks
Pre-requisite for installing CodeBlock is lsquolibwxgtkrsquo which is available in ubuntu software center Thispackage will be already installed in your system3 It is also advised to install lsquobuild-essentialrsquo packageand update repository list In case the libwxgtk is not installed it can be installed from command lineusing command given in listing 1 [3] CodeBlock is available in Ubuntursquos repository It can be installedusing Ubuntu Software Center or it can also be installed using command line as given in listing 2

4 Working with CodeBlock on Ubuntu
In this section we discuss writing and building three projects First project (hello worldc) is simpleprogram which displays hello world on output The other project (linec) uses graphicsh header file anddisplays a line graphicsh is not supported by gcc which is the default CC++ compiler on UbuntuThe third project (3polycpp) uses simplecpp package and draws three polygons on output We have toinstall some packages include few libgraph libraries during building the project with graphich headerfile
41 Installation of CodeBlocks
Pre-requisite for installing CodeBlock is lsquolibwxgtkrsquo which is available in ubuntu software center Thispackage will be already installed in your system3 It is also advised to install lsquobuild-essentialrsquo packageand update repository list In case the libwxgtk is not installed it can be installed from command lineusing command given in listing 1 [3] CodeBlock is available in Ubuntursquos repository It can be installedusing Ubuntu Software Center or it can also be installed using command line as given in listing 2

4 Working with CodeBlock on Ubuntu
In this section we discuss writing and building three projects First project (hello worldc) is simpleprogram which displays hello world on output The other project (linec) uses graphicsh header file anddisplays a line graphicsh is not supported by gcc which is the default CC++ compiler on UbuntuThe third project (3polycpp) uses simplecpp package and draws three polygons on output We have toinstall some packages include few libgraph libraries during building the project with graphich headerfile
41 Installation of CodeBlocks
Pre-requisite for installing CodeBlock is lsquolibwxgtkrsquo which is available in ubuntu software center Thispackage will be already installed in your system3 It is also advised to install lsquobuild-essentialrsquo packageand update repository list In case the libwxgtk is not installed it can be installed from command lineusing command given in listing 1 [3] CodeBlock is available in Ubuntursquos repository It can be installedusing Ubuntu Software Center or it can also be installed using command line as given in listing 2

4 Working with CodeBlock on Ubuntu
In this section we discuss writing and building three projects First project (hello worldc) is simpleprogram which displays hello world on output The other project (linec) uses graphicsh header file anddisplays a line graphicsh is not supported by gcc which is the default CC++ compiler on UbuntuThe third project (3polycpp) uses simplecpp package and draws three polygons on output We have toinstall some packages include few libgraph libraries during building the project with graphich headerfile
41 Installation of CodeBlocks
Pre-requisite for installing CodeBlock is lsquolibwxgtkrsquo which is available in ubuntu software center Thispackage will be already installed in your system3 It is also advised to install lsquobuild-essentialrsquo packageand update repository list In case the libwxgtk is not installed it can be installed from command lineusing command given in listing 1 [3] CodeBlock is available in Ubuntursquos repository It can be installedusing Ubuntu Software Center or it can also be installed using command line as given in listing 2
1 $ sudo aptminusget i n s t a l l l ibwxgtk2 8minus02 $ sudo aptminusget i n s t a l l bui ldminuse s s e n t i a l3 $ sudo aptminusget update

When command line prompts for [Yn] enter lsquoyrsquo and press enter When CodeBlock is run for first timeIt asks for default compiler Select the appropriate compiler to proceed further We have used lsquoGNUGCC Compilerrsquo
42 Installation of packages for graphicsh header file
GCC compiler does not support graphicsh conioh windowsh and few other header files that workson Turbo C or Borland C graphicsh header files enables programmer to write simple cc++ graphicsprograms In Ubuntu gcc is default cc++ compiler thus we have to make some settings for gcc tosupport graphics[4] We will start with installing some packages from command line as given in listing 3

4 Working with CodeBlock on Ubuntu
In this section we discuss writing and building three projects First project (hello worldc) is simpleprogram which displays hello world on output The other project (linec) uses graphicsh header file anddisplays a line graphicsh is not supported by gcc which is the default CC++ compiler on UbuntuThe third project (3polycpp) uses simplecpp package and draws three polygons on output We have toinstall some packages include few libgraph libraries during building the project with graphich headerfile
41 Installation of CodeBlocks
Pre-requisite for installing CodeBlock is lsquolibwxgtkrsquo which is available in ubuntu software center Thispackage will be already installed in your system3 It is also advised to install lsquobuild-essentialrsquo packageand update repository list In case the libwxgtk is not installed it can be installed from command lineusing command given in listing 1 [3] CodeBlock is available in Ubuntursquos repository It can be installedusing Ubuntu Software Center or it can also be installed using command line as given in listing 2
1 $ sudo aptminusget i n s t a l l l ibwxgtk2 8minus02 $ sudo aptminusget i n s t a l l bui ldminuse s s e n t i a l3 $ sudo aptminusget update

Figure 71 shows CodeBlock along with itrsquos logo in Ubuntu Software Center while figure 72 showsinstallation of CodeBlock using command line In figure 72 four underlined lines are
line 1 Command to install the CodeBlock
line 2 Packages installed along with CodeBlock
line 3 Packages suggested along with CodeBlock installation libwxgtk284 package as mentioned aboveis already installed in your system libwxgtk28-dev package is not required
line 4 Final list of packages that will be installed in your system
When command line prompts for [Yn] enter lsquoyrsquo and press enter When CodeBlock is run for first timeIt asks for default compiler Select the appropriate compiler to proceed further We have used lsquoGNUGCC Compilerrsquo
42 Installation of packages for graphicsh header file
GCC compiler does not support graphicsh conioh windowsh and few other header files that workson Turbo C or Borland C graphicsh header files enables programmer to write simple cc++ graphicsprograms In Ubuntu gcc is default cc++ compiler thus we have to make some settings for gcc tosupport graphics[4] We will start with installing some packages from command line as given in listing 3
