Derived classes and singleton

Question

If I have two classes "A" and "B", is it OK to derive B from A and then make B a Singleton?.

Thanks for your help.

Answer 1

Um, sure. Nobody is going to stop you.

If it's okay to make "some class" a singleton ^* , just imagine B being a new "some class". (It just happens to be derived from A.)

^* Though, do you really need a singleton ? (No.)
