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.

What is the syntax of multilevel inheritance?

Class A

{

Statements of Class A

};

Class B: public class A

{

Statements of Class  b

};

Class C: public class B

{

Statements of Class  C

};

Basic Program of multi-level inheritance

#include<iostream>
using namespace std;
class sum
{
protected:
int n1;
};
class child1 : public sum
{
protected:
int n2;
};
class child2 : public child1
{
public:int sum()
{
cout<<"enter n1"<<endl;
cin>>n1;
cout<<"enter n2"<<endl;
cin>>n2;
cout<<"sum="<<n1+n2<<endl;
}
};
int main()
{
child2 myobject;
myobject.sum();
}

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++.
