relatively new to C++... a little template help?

#include<iostream.h>
#include<conio.h>

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

void main()
{
char letter = 'A';
int integer= 5;
double money= 2.25;
cout<<"The square of "<<letter<<" is "<<square(letter)<<endl;
cout<<"The square of "<<integer<<" is "<<square(integer)<<endl;
cout<<"The square of "<<money<<" is "<<square(money)<<endl;
getch();
}

I receive the error:

error C2679: binary '<<' : no operator defined which takes a right-hand operand of type 'void' (or there is no acceptable conversion)

on each of my cout statements.

Thanks in advance!

you have to include the pre processor command
include <math.h>
in order to peform the math functions for squaring.

your square function is of type void.
while at the same time, the function
is trying to return a value (i'm assuming)
of type T. just change void to T.
that should do the trick.

This is a Visual Basic forum, not a C++ forum.

Yes I agree with facecheekwall, your template function has a void type and you set your function to return a value it should not be void it should be I think in this case T. I agree with that, it should do it for you
