LABORATORY CULTURE

Every student is assigned a Lab Work of three hours per week and is advised to be in the Lab within

five minutes after the commencement of the period. Attendance is a compulsory factor which carries

certain marks of discipline; therefore students are expected to be regular and attentive in the lab. The

students are also expected to maintain the discipline and decorum of the lab. At the same time a record

has to be maintained by the students regarding their practical work, which they have to submit on the

time of their respective Turns for evaluation. Any violation to these acts will be considered as a mater

of indiscipline. Every student will be allocated a PC and student will work on the same PC throughout

the year. Students have to maintain the laboratory records in which they will write or put the printout

of the programs and their outputs.

4. Work on allocated computer.

5. Seek the permission of the instructor before entering the lab.

6. All written work to be done in lab and gel is counted on the same day.

GUIDELINES FOR THE IMPLEMENTATION OF THE PROGRAMMING IN C++LAB FOR

STUDENTS

1. The faculty should provide the complete plan of the lab which will be followed

throughout the complete semester.2. The guidelines must be followed strictly.

3. Each student should be evaluated as per his/ her performance in the lab without considering his/

her

previous performance.

4. The programs which are to be coded in C / C++ must be coded in either VC++ or Eclipse in Linux

OS.

No other IDE or editor will be allowed at any cost. If any other tool is being used then the whole.

responsibility of the act will the lab faculty and will be answerable to HOD.

5. It should be noted down that no student may copy the source code of another student for any

program i.e. plagiarism should not take place.

6. If at any stage, it is found that plagiarism is being done, then both the students (one who will copy

and the one who will let him/ her to do so) will be awarded 0 (zero) marks for that assignment

as well as the marks given in previous assignment will be reduced to half of the given marks.

7. For each program, the student will write the source code, get it checked from the faculty and

should take a printout of the code and get signed from the faculty. Then that print out will be

attached to the lab record and will submit the record to the respective faculty.

8. It should be noted that the lab records will not be given to students in any case. Those will

remain with the faculty member in the lab only. And no student will take the lab record with

him/ her; it should be taken and submitted after the completion of each assignment.

INTRODUCTION OF OBJECT ORIENTED PROGRAMMING

Programming language which serves as the intelligent of any computer systems has evolved

tremendously since it was first developed. Currently, in most electronic Devices ranging from

mobile handset to washing machine even to cars have computer Embedded system and thus

requires some form of programming language to govern the Operation of those devices.

Object-oriented programming (OOP) is a programming paradigm that uses abstraction to Create

models based on the real world. It utilizes several techniques from previously Established

paradigms, including modularity, polymorphism and encapsulation.Even though it originated in

1960s, OOP was not commonly used in mainstream software application development until the

1990s. Today, many popular programming languages such as Java, JavaScript, C# , C++, Python

support OOP.

OOP may be seen as a collection of cooperating objects, as opposed to a traditional view in which

a program may be seen as a collection of functions, or simple as a list of instructions to the

computer. In OOP, each object is capable of receiving messages, processing data, and sending

messages to other objects. Each object can be viewed as an independent little machine with a

distinct role or responsibility.

OOP is intended to promote greater flexibility and maintainability in programming, and is

widely popular in large-scale software engineering. By virtue of its strong emphasis on

modularity, object oriented code is intended to be simpler to develop and easier to understand

later on, lending itself to more direct analysis, coding, and understanding of complex situations and

procedures than less modular programming methods.
