class B : public A //B is derived from class base

{

   public:

 void product()

 {

     cout << "\nProduct= " << x * y;

 }

};

class C : public A //C is also derived from class base

{

   public:

 void sum()

 {

       cout << "\nSum= " << x + y;

 }

};

int main()

{

   B obj1;          //object of derived class B

   C obj2;          //object of derived class C

   obj1.product();

   obj2.getdata();

   obj2.sum();

   return 0;
