Practical : 8

Subject : Object Oriented Programming with C++

Aim :  C++ program calculate the area of circle, rectangle and square using function overloading

Source Code :

#include<iostream.h>

#include<conio.h>

class pratik

{

public:

area(int a)

{

int x=a*a;

cout<<"\n length is : "<<a;

cout<<"\n area of squre is : "<<x<<endl;

}

area(int b,int c)

{

int y=b*c;

cout<<"\n length is : "<<b<<"\n width is : "<<c;

cout<<"\n area of rectangle is : "<<y<<endl;

}

area(double r)

{

double z=3.14*r*r;

cout<<"\n redious is : "<<r;

cout<<"\n area of circle is : "<<z<<endl;

}

};

void main()

{

clrscr();

pratik a,b;

a.area(20,4);

a.area(5);

a.area(5.55);

getch();

}

Output :
