Template problem

[Richard Hayden]

Hi,

I'm just learning about C++ templates and can't understand why the
following code is not working as expected:

/*************************************\

#include <iostream>

template<class C>C func(C c) {
return c;
}

int main(int argc, char** argv) {
std::cout << afunc(23); // OUTPUTS '5' INSTEAD OF '23'
}

/*************************************\

I'd be very grateful if someone could explain to me why this code is not
working as expected and outputting '5' instead of '23'.

Thanks,

This is not 'func' but 'afunc'.

}

Thanks,

In the part of your code that you did not post, there is a function called
afunc that outputs 5.

It's hard to say without seeing the definition of afunc. Or did you
mean to call func rather than afunc?
