Hybrid Inheritance in c++

Hybrid inheritance is combination of two or more inheritances such as single,multiple,multilevel or Hierarchical inheritances.
In the below program class B inherits property(member function) of class A which is base class and class D inherits property from class B and class C.

#include<iostream.h>

#include<conio.h>

 

class A     //Base class

{

public:

int l;

void len()

{

cout<<"\n\nLenght :::\t";  

cin>>l;                  //Lenght is enter by user      

}

};

class B :public A   //Inherits property of class A

{

public:

int b,c;

void l_into_b()  

{

len();

cout<<"\n\nBreadth :::\t";

cin>>b;                      //Breadth is enter by user

c=b*l;                       //c stores value of lenght * Breadth i.e. (l*b) .  

}

};

 

class C

{

public:

int h;

void height()

{

cout<<"\n\nHeight :::\t";

cin>>h;                  //Height is enter by user

}

};

 

//Hybrid Inheritance Level

class D:public B,public C

{

public:

int res;

void result()

{

l_into_b();

height();

res=h*c;                          //res stores value of c*h  where c=l*b and h is height which is enter by user

cout<<"\n\nResult (l*b*h) :::\t"<<res;

}

};

 

int main()

{

clrscr();

D d1;

d1.result();

getch();

}
