Member function pointer assignment

[acppdummy]

I have a class with member functions and a pointer like this:

class MyClass{
private:
    typedef void(MyClass::*memFnPtr_t) (); 
public:
    memFnPtr_t fnptr;
    void fn1();
    void fn2();
};

Now in a regular function I create an instance of the class and try to assign the pointer:

MyClass mc;
mc.fnptr = &mc.fn1;

The compiler does not like it and suggests this instead:

mc.fnptr = &MyClass::fn1;

This seems to work but what if I have two instances of the class:

MyClass mc1, mc2;

How does the compiler know to distinguish between

mc1.fn1

and

mc2.fn1

when the assignment now looks identical:

mc1.fnptr = &MyClass::fn1;
mc2.fnptr = &MyClass::fn1;

?



Thanks in advance!
