class inheritance hybrid code example

Example: hybrid inheritance template

#include<iostream.h>#include<conio.h>int a,b,c,d,e; class A    {protected:public:void getab()    {cout<<"\n ENter a and b value:";cin>>a>>b;        }}; class B:public A    {protected:public:void getc()    {cout<<"Enter c value:";cin>>c;    }}; class C    {protected:public:void getd()    {cout<<"Enter d value:";cin>>d;    }}; class D:public B,public C    {protected:public:void result()    {getab();    getc();getd();    e=a+b+c+d;cout<<"\n Addition is :"<<e; }}; void main()    {clrscr();D d1;d1.result();getch();        }
