default argument for template parameter for class enclosing

Question

code:

template  >
class stack
{
    public:
        stack() {}
        temp         


        

Answer 1

That default parameter is, by syntax, a default parameter to the class, and it only makes sense at the class declaration.

If you would call that function ...

stack().empty();

you only have the template parameters on the site of the class name, for which you already provided default parameters at the point of the template class declaration.

You can solve the issue by simply removing the default parameter from the function definition:

template
bool stack::empty(){
    return container.empty();
}
