Go back to my original question:

How to create a variable which hold a particular function pointer of a class, and
can be invoked on different objects of that class:

fp = &(A.f);
A a1, a2;
a1.fp();   // how to make this invocation work?

And I have one more requirement that even if A.f() and A.g() have same signature,

fp = &(A.g);   // expect compiler report error here.

How to declare the type of such fp?
