Calling C++ class methods via a function pointer

Question

How do I obtain a function pointer for a class member function, and later call that member function with a specific object? I’d like to write:

class Dog : A         


        

Answer 1

typedef void (Dog::*memfun)();
memfun doSomething = &Dog::bark;
....
(pDog->*doSomething)(); // if pDog is a pointer
// (pDog.*doSomething)(); // if pDog is a reference
