The issue is I have All_A & All_B - how do I differentiate them? Am I supposed to do All_B.Term() just to differentiate them?

When you call Term() inside CAll::Display(), it is the same as this->Term(). It is called as a member function of the same object. So All_A.Display() will end up calling Term() upon All_A, and ALL_B.Display() will end up calling Term() upon All_B. As soon as you have three objects you had better start thinking about std::vector<CAll>.

Am I right to assume that inside the member function, I call ALL_B.Display() & All_A.Display() since there 2 objs ( and it would be redundant if there are only one object ).

Am I right to assume that inside the member function, I call ALL_B.Display() & All_A.Display() since there 2 objs I don't know; what are you trying to accomplish? I certainly don't see any reason to call both of them from within some other member function, but you might have a reason. Quote: ( and it would be redundant if there are only one object ). No, with only one object you certainly cannot call functions of two objects. Post a small but complete compilable sample of the code you are trying to use.
