Concepts and Syntax Inheritance: creating a new class that absorbs (inherits) an existing class's capabilities, then customizes or enhances them. Base Class (also called parent class or superclass): the existing class Derived Class (also called the child class or subclass) : the new class is - a" relationship: phrase that indicates inheritance Private private members of a class are only accessible in the member functions of the class where they are defined. private members of a base class are inherited, but not directly accessible in a derived class. Public public members of a class are accessible in any function Class Hierarchy: a diagram showing the inheritance relationships among classes
