Hybrid - Inheritance in C++

5.) Hybrid - Inheritance  


What is Hybrid ?

The inheritance in which the derivation of a class involves more than one form of any
inheritance is called hybrid inheritance. Basically C++ hybrid inheritance is   combination of two or more types of inheritance.

C++ Hybrid Inheritance Example

Here is a simple program to illustrate the concept of hybrid inheritance in C++.

// hybrid inheritance.cpp

#include <iostream>

using namespace std;

class A

{

  public:

  int x;

};

class B : public A

{

  public:

  B()      //constructor to initialize x in base class A

  {

     x = 10;

  }

};

class C

 {

  public:

  int y;

  C()   //constructor to initialize y

  {

      y = 4;

        }

};

class D : public B, public C   //D is derived from class B and class C

{

  public:

  void sum()

  {

      cout << "Sum= " << x + y;

  }

};

int main()

{

         D obj1;          //object of derived class D

  obj1.sum();

  return 0;

}                //end of program

Output

Sum= 14
