Copy constructor of template class

Question

I read that template copy-con is never default copy onstructor, and template assignment-op is never a copy assignment operator.

I couldn\'t understand why this res

Answer 1

I can't comment on why this is how it is, but here's how you write a copy constructor and assignment operator for a class template:

    template 
    class A
    {
      public:
        A(const A &){}
        A & operator=(const A& a){return *this;}
    };

and that's it.
The trick here is that even though A is a template, when you refer to it inside the class as A (such as in the function signatures) it is treated as the full type A.
