It is possible in C++ to use the save function name for the
no of lines for different intention. Defining multiple
function with same name is know as function overloading or
function polymorphism.

Polymorphism means one function having many forms.
The overloading function must be different in its argument
list and with different data types.

Example:
#include<iostream.h>
#include<conio.h>
int square (int);
float square (float);
void main()
{
int a = 5;
float b = 2.5;
clrscr();
cout<<"square = "<<square(a);
cout<<"\n square = "<<square(b);
getch();
}
int square(int s)
{
return (s*s);
}
float square (float j)
{
return (j*j);
}

Overloading;
