Types of Inheritance in C++

This article contains Types of Inheritance in C++.

To understand types of inheritance in c++, you must know about Inheritance in C++.

Types of Inheritance in C++

(1) Single Inheritance

(2) Multiple Inheritance

(3) Multilevel Inheritance 

(4) Hierarchical Inheritance

(5) Hybrid Inheritance

Single Inheritance

In single inheritance, a derived class inherits properties of only one base class or super class. This is most simple type of inheritance.

Example:

class A

{

        public:

            int a;

};

class B: public A

{

        public:

            int b;

};

Multiple Inheritance

In multiple inheritance, a derived class inherits from two or more than two base classes.

Example:

class A

{

       public:

           int a;

};

class B

{

       public:

           int b;

};

class C: public A, public B

{

       public:

           int c;

};

Multilevel Inheritance 

In multilevel inheritance, a derived class inherits from one base class and some other derived inherits from that derived class and so on.

Example:

class A

{

       public:

           int a;

};

class B: public A

{

       public:

           int b;

};

class C: public B

{

       public:

           int c;

};

Hierarchical Inheritance

In hierarchical inheritance, multiple derived class inherits from single base class.

Example:

class A

{

       public:

           int a;

};

class B: public A

{

       public:

           int b;

};

class C: public A

       public:

           int c;

};

Hybrid Inheritance 

Hybrid inheritance is a combination of two or more inheritance.

Example:

class A

{

       public:

           int a;

};

class B: public A

{

       public:

           int b;

};

class C: public A

       public:

           int c;

};

class D: public B, public C

{

      public:

          int d;

};
