Explanation / Answer
Dear,
STL does not use inheritance to any great extent. Instead itrelies heavily on composition of its generic components to providefor specialization. Thus stack does not inherit from list, deque orvector. It is instead a generic composition from any containerproviding the required functionality. We will create multipleinheritance (i.e. class A: public B, public C {}) unless creatinginterface instead of implementation. Otherwise, you'll run into allsorts of problems with conflicting members, especially if someoneelse owns a base class. The best time to use multiple inheritanceis when a subclass multiply inherits from abstract base classeswith only pure virtual functions.
