Question

Design a class named Rectangle to represent a rectangle. The class contains:

we have to make 3 files header file , one .cpp file for function and one more main cpp file

Design a class named Rectangle to represent a rectangle. The class contains: Two double data fields named width and height that specify the width and height of the rectangle. A constructor that creates a rectangle with the specified width and height. The accessor and mutator functions for all data fields. They are: A function named setWidth that sets the value of the data field width. A function named setHeight that sets the value of the data field height. A function named getWidth that returns the value of the data field width. A function named getHeight that returns the value of the data field height. A function named getArea that returns the area of this rectangle. A function named getPerimeter that returns the perimeter of this rectangle. Write a header file containing the class definition and a C++ program containing the functions for the class. Write a test program testing the class. This test program will create a Rectangle object, assign width 4 and height 40 to the object, and display the properties of the object (its width, height, area, and perimeter).

Explanation / Answer

#include<iostream.h>

class rectangle

{

float width, height;

public:

rectangle()

{width=0;

breadth=0;

}

void setWidth(float a)

{width=a;

}

void setwHeight(float b)

{width=b;

}

float getWidth()

{return width;}

float getHeight()

{return height;}

float getArea()

{return width*height;}

float getPerimeter()

{return 2*(width+height);}

};

void main()

{rectangle a;

a.setWidth(4);

a.setHeight(40);

cout?
