Answer to Question #211836 in C++ for Hemambar

Question

definition of inheritance, types of inheritance with different access specifiers. All the concepts should be illustrated with appropriate diagrams and example programs.

Answer 1

Inheritance in child class can be described as inheriting the features and behaviour/properties from the parent class. Here, the class that contains these members is called the ​base class​ and the class that inherits these members from the base class is called the ​derived class ​of that base class​.

Access Modifiers

Following modifiers should be used at the time of creation of a derived class from a base class:

●    Public

●    Private

●    Protected

The ​public​ data members can be accessed by any of its child class as well as the class objects.

Private ​data members are inaccessible outside the class.

Protected ​data members can only be accessed by the derived classes but are inaccessible using the class objects.

 

Inheritance: Syntax

Inherited class can be defined as follows:

class derived_class_name :access_modifierbase_class_name {

       ----

       ----

};

 

Inheritance: Types

There are six types of inheritance:

●    Single Inheritance: ​Here, a child class is created from a single parent class.

●    Multi-level Inheritance: ​Here, there is a series of derived classes, which means a derived class is created from another derived class.

●    Multiple Inheritance: ​Here, a child class is created from more than one parent/base class.

●    Multipath Inheritance: ​In this type of inheritance, a derived class is createdfrom other derived classes and the same base class of other derived classes.

●    Hierarchical Inheritance: ​Here, ​more than one derived classes are createdfrom a single base class, and further, child classes act as parent classes formore than one child class.
