Function overloading

It refers to using the same function  name to perform the varity of different function

The difference in the Function call is made on the Basis of the following methods:

(1) Number of arguement

(2) Type of arguement

(3) Sequence of arguement

consider the following program:

 #include <iostream.h>

#include <conio.h>

void area( int side)

{

cout<<"Area of Square "<<side*side;

}

void area ( int length,int width)

{

cout<<length*width;

}

void area ( double radius)

{

cout <<3.14*radius*radius;

}

void main()

{

area(5,6);

area(8);

area (5.6);

getch();

}
