CPP Program to implement function overloading.

 Code :

#include<iostream>

using namespace std;

int volume(int);

double volume(double,int);

long volume(long,int,int);

int main()

{

cout<< volume(10)<<endl;

cout<< volume(2.5,8)<<endl;

cout<< volume(100,75,15)<<endl;

return 0;

}

int volume(int s)

{

return(s*s*s);

}

double volume(double r,int h)

{

return(3.14519*r*r*h);

}

long volume(long l,int b,int h)

{

return(l*b*h);

}

Output :
