The BIG Picture base class contains data and operations common to all derived classes. Rather than ng these fields in each derived class, we let the derived classes inherit them class. A derived class can override inherited virtual methods and add from the base additional methods and data fields. nheritance supports the IS-A relationship in which a derived class object is also a type of base class object.
