Hierarchical Inheritance in C++

 C++ Hierarchical Inheritance When several classes are derived from common base class it is called hierarchical inheritance . In C++ hierarchical inheritance , the feature of the base class is inherited onto more than one sub-class. For example, a car is a common class from which Audi, Ferrari, Maruti etc can be derived. Following block diagram highlights its concept. Hierarchical Inheritance Block Diagram As shown in above block diagram, in C++ hierarchical inheritance all the derived classes have common base class. The base class includes all the features that are common to derived classes. As in other inheritance, based on the visibility mode used or access specifier used while deriving, the properties of the base class are derived. Access specifier can be private, protected or public.

A Derived class is defined as the class derived from the base class. The Syntax of Derived class: class  derived_class_name :: visibility-mode base_class_name   {        // body of the derived class.    }       Where, derived_class_name : It is the name of the derived class. visibility mode : The visibility mode specifies whether the features of the base class are publicly inherited or privately inherited. It can be public or private. base_class_name : It is the name of the base class. When the base class is privately inherited by the derived class, public members of the base class becomes the private members of the derived class. Therefore, the public members of the base class are not accessible by the objects of the derived class only by the member functions of the derived class. When the base class is publicly inherited by the derived class, public members of the base class also become the public members of the derived class. Therefore, the public
