He meant overloading. Of course your variant is better, but he does not
seem to understand what a template ist.

int cube (int x)
{
 return x*x*x;
}
float cube (float x)
{
 return x*x*x;
}
double cube (double x)
{
 return x*x*x;
}

But this is not very good because of one thing: try

long double x;
cube (x);

and the compiler will not know whether to use the float or double version.
