Using overloaded operators on pointers

Question

I overloaded the << operator of a class. How do I have to overload the operator if I want to use it on pointers, like the following?

class A {
    std::str         


        

Answer 1

You cannot do that. Operator functions are only considered for operands that have enumeration or class types among them.

You after all shift a pointer, but not a class. You need to explicitly say that you want to shift into a class object by dereferencing the pointer first.
