function overloading

Function Overloading:

Create more than one function with the same name.
The area of square depends on the length of one side.
The area of retangular depends on width and length.
The area of circle depends on radius.
We can have the following three functions in the same function name.
int Area(int side)
int Area(int width, int length)
float Area(float radius)

#include <iostream.h>

int Area(int side);
int Area(int width, int length);
float Area(float radius);

void main()
{
int s, w, l;
float r;

cout<<"Enter the length of a side of a square. \n";
cin >> s;
cout<<"The area of the square is "<<Area(s) <<endl;
cout<<"Enter the length and width of a retangle. \n";
cin >> l >> w;
cout<<"The area of the retangle is "<<Area(w,l) <<endl;
cout<<"Enter the radius of circle. \n";
cin >> r;
cout<<"The area of the circle is "<<Area(r) <<endl;

}

int Area(int side)
{
return side * side;
}
int Area(int width, int length)
{
return width * length;
}
float Area(float radius)
{
return 3.14 * radius * radius;
}
