I'll do your homework this time, but not again.  Even once is probably a
disservice to you:

#include <iostream>
using namespace std;

template < class T > T cube(T x)
{
    return x * x * x;
}

int main(void)
{
    int ix = 3;
    float fx = 3.76f;
    double dx = 7.3;
    long double ldx = -24.31L;
    cout << "int example.  " << ix << " cubed is " << cube(ix) << endl;
    cout << "float example.  " << fx << " cubed is " << cube(fx) << endl;
    cout << "double example.  " << dx << " cubed is " << cube(dx) << endl;
    cout << "long double example.  " << ldx << " cubed is " << cube(ldx) <<
        endl;
    return 0;
}


int example.  3 cubed is 27
float example.  3.76 cubed is 53.1574
double example.  7.3 cubed is 389.017
long double example.  -24.31 cubed is -14366.6
