#include<iostream>
using namespace std;
class student {
protected:
    int rno, subject1, subject2,subject3,subject4,subject5,subject6;
public:
    void get() {
        cout << "Enter the Roll no :";
        cin>>rno;
        cout << "Enter the six marks   :";
        cin >>subject1>>subject2>>subject3>>subject4>>subject5>>subject6;
    }
};
class exam {
protected:
    int subject1;
	int subject2;
	int subject3;
	int subject4;
	int subject5;
	int subject6; // sm = Sports mark
public:
    void getsm() {
        cout << "\nEnter the First subject mark :";
        cin>>subject1;
        cout << "\nEnter the second subject mark :";
        cin>>subject2;
        cout << "\nEnter the third subject mark :";

        cin>>subject6;
    }
};
class result : public student, public exam {
    int tot, avg;
public:
    void display() {
        tot = subject1+subject2+subject3+subject4+subject5+subject6;
        avg = tot / 3;
        cout << "\n\n\tRoll No    : " << rno << "\n\tTotal      : " << tot;
