Simple question about heritances

[SkripT]

Hi all, I have a class with functions A and B. Function A calls to B. Well, I need to subclass this class because I need to reimplement the function B (the function A remains the same). The question is: in the new class, when A calls to B wich "version" of B is called: the "new" or the "old" one. If the answer is the version from the parent class (as I think) what's the best solution to make that the function A calls to the new B in the subcalassed class? Defining B as virtual in the parent class and reimplement it in every subclass, maybe?

Thanks.

Defining B as virtual in the parent class and reimplement it in every subclass, maybe?

Yes, but you don't have to reimplement it everywhere.

Yes, but you don't have to reimplement it everywhere.

Do you mean jacek that If I define B in the main class as virtual but I also implement it, it will work as I need?

[fullmetalcoder]

in both classes declares B as virtual and reimplement it then everything will work fine : that's the point of dynamic function linking.

Thanks both!
