Objective

The objective of this assignment is to provide hands on experience of using

User defined manipulators

Static member

Copy Constructor

Follow C/C++ rules while writing variables names, function name

etc.

Use only Dev-C++ IDE for this assignment.

Assignment

Problem Statement:

You are required to write a program of class rectangle named CRectanglwhich should draw two rectangles by using iTop, iRight, iBot, and

iLeft. Then program should calculate the area of both. Number o

rectangles should be displayed to user by using static variabl

counter which would keep track of increment or decrement o

rectangles. Dynamically Create another rectangle by using copy

constructor and increment in counter should be displayed on screen

Decrement in static variable counter (after de-allocating memory which

was dynamically allocated) should be displayed again on screen.

Sample Output

Area of rectangle 1 is 6400

Area of rectangle 2 is 5600

The number of rectangles is 2

After using copy constructor, total number of rectangles is 3

The number of rectangles is 2

Detailed Description:

1. The class should have 4 members: iTop, iRight, iBot, and iLeft, all of

type int.

2. Area of both rectangles should be calculated by using iTop, iRight,

iBot, and iLeft.

3. It should have a default constructor and a copy constructor.

4. It should have a destructor.

5. It should contain all required getters and setters.

6. It should contain a static member, iRefCount, which keeps track of the

number of CRectangle objects. Increment it in the constructor, and

decrement it in the destructor.

Hint:

CRectangle would implement rectangles by using left, right, top and bottom

and calculate their areas to compare.

GOOD LUCK

Deadline:

Your Assignment solution must be submitted on or before Jan 31st, 2011.
