Calling a member function using function pointers from another class's instance

Question

#include
#include
using namespace std;
class Base;
typedef void (Base::*function)();
class Base
{
public:
    function f;
    Base()
    {         


        

Answer 1

f doesn't appear to be in scope in Handler::CallFunction. I'm guessing you meant to call the b->f using b as this, as it (b->*(b->f))(). When I make this change, your code compiles and prints out something sane.
