Function template in non-template class

Question

I\'m sure that it is possible but I just can\'t do it, which is: How can I define function template inside non-template class? I tryied something like this:

clas         


        

Answer 1

Don't put the <T> after the function name. This should work:

template<class T>
void Stack_T::put(const T& obj)
{
}

This still won't work if the function definition is not in the header file. To solve this, use one of:

• Put the function definition in the header file, inside the class.
• Put the function definition in the header file after the class (like in your example code).
• Use explicit template instanciation in the header file. This has serious limitations though (you have to know all possible values of T in advance).
