A member (either data member or member function) declared in a protected section of a class can only be accessed by member functions and friends of that class, and by member functions and friends of derived classes.

A protected member is used to remove that mwember from the public interface of the class. Classes with protected members are "incomplete " and rely on derioved classes to complete the implementation. Classes like these are called component, or "mix-in" classes.
