title: Derived Classes and Protecting Member Data of Base Class
body: <p>I'm wondering if there is some way to declare a variable that is member data of a base class so that it is not inherited by a class derived from it.  I have some member data in my base class that should not be part of objects of the derived class, so I'd like to separate what should be inherited from what should not.  Is there some way to do this?</p>
