A member (either data member or member function) declared in a protecte

Answer 1

You are not accessing protected function in your derived class, you are trying to overload it and promote from protected to public. This is a forbidden action, you only can hide functions in derived class, e.g. overload protected function as a private.

Accessing protected function means call it from some member of a class:

class Y : public X
{
public:
    void call() {
      fun();
    }
}

or like you call it by objX.fun(); is also correct.
