Hybrid Inheritance in C++.

Hybrid Inheritance in C++.

• Hybrid inheritance is the process of combining of more than one type of inheritance.
• Following syntax will make you understand hybrid inheritance.

class A

{

     .........

};

class B : public A

{

     ..........

} ;

class C

{

     ...........

};

 class D : public B, public C

{

     ...........

};

// Hybrid inheritance implementation.

#include <iostream.h>

#include <conio.h>

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;

}               

Expected Output:-

Sum= 14

// Hybrid inheritance implementation.

#include <iostream.h>

#include <conio.h>

class A  

{  

    protected:  

    int a;  

    public:  

    void get_a()  

    {  

       std::cout << "Enter the value of 'a' : " << std::endl;  

       cin>>a;  

    }  

};  

  

class B : public A   

{  

    protected:  

    int b;  

    public:  

    void get_b()  

    {  

        std::cout << "Enter the value of 'b' : " << std::endl;  

       cin>>b;  

    }  

};  

class C   

{  

    protected:  

    int c;  

    public:  

    void get_c()  

    {  

        std::cout << "Enter the value of c is : " << std::endl;  

        cin>>c;  

    }  

};  

  

class D : public B, public C  

{  

    protected:  

    int d;  

    public:  

    void mul()  

    {  

         get_a();  

         get_b();  

         get_c();  

         std::cout << "Multiplication of a,b,c is : " <<a*b*c<< std::endl;  

    }  

};  

int main()  

{  

    D d;  

    d.mul();  

    return 0;  

}  

Expected Output:-

Enter the value of 'a' :

10              

Enter the value of 'b' :    

20      

Enter the value of c is :   

30  

Multiplication of a,b,c is : 6000
