INHERITANCE EXAMPLE1

Description:

Here some examples of "Inheritance" (important concept of c++) are presented.

CODE:

#include<iostream>

#include<conio.h>

using namespace std;

class B

{

public:

            int m,a;

            int product1()

            {

             return a*m;

            }

};

class D:public B

{

public:

            int n;

            int product2()

            {

             return n*product1();

            }

};

int main()

{

 D d1;

 d1.m=5;

 d1.a=4;

 d1.n=3;

 cout<<"product1 = "<<d1.product1()<<endl;

 cout<<"product2 = "<<d1.product2()<<endl;

 getche();

 return 0;

}

OUTPUT:

product1 = 20

product2 = 60
