Multi level inheritance in C++ with Syntax and Examples

Multilevel inheritance in C++ OOP – Example program

In this tutorial we will learn about the followings;

  1. Multilevel inheritance in C++ OOP
  2.  Example of multi-level inheritance in C++ OOP
  3. The syntax of multi-level inheritance in C++ OOP
  4. The basic program of multi-level inheritance  in C++ OOP

What is Multi-level inheritance?

A derived class can be derived from another derived class. A child class can be the parent of another class.

Give an example of multilevel inheritance?

Class C is a child of class B and class B is child class of class A.

multivel child parent relationship of classes
Figure: multi-level inheritance.

What is the syntax of multilevel inheritance?

Basic Program of multi-level inheritance

Here in this example there is multi level inheritance because

  • Declaration of variable n1 is inherited from sum to child1 
  • Declaration of Variable n2 is inherited from chil1 to child2 
  • Child2 now uses one variable of its first parent and one variable of its grandfather.

So, this is a better example of multilevel inheritance.

Difference between multi level and multiple Inheritance in C++

Here, i am showing you a comparison of multiple and multi level inheritance in C++.

Multilevel Inheritance Multiple Inheritance
In Multilevel Inheritance parent shares inherits with child and then child becomes parent of other class and share the resources of parent to its child.In Multiple Inheritance a class inherits from more than one parent classes.

Class Levels

Multilevel Inheritance has three class levels namely, base class, intermediate class and derived class.Multiple Inheritance has two class levels namely, base class and derived class.

 Usage

Multilevel Inheritance is widely used as compared to multiple inheritance.Multiple Inheritance is complex as compared to multi level inheritance and not widely used.
