class student {
protected:
    int rno, m1, m2;
public:
    void get() {
        cout << "Enter the Roll no :";
        cin>>rno;
        cout << "Enter the two marks   :";
        cin >> m1>>m2;

class sports {
protected:
    int sm; // sm = Sports mark
public:
    void getsm() {
        cout << "\nEnter the sports mark :";
        cin>>sm;
    }
};
class statement : public student, public sports {
    int tot, avg;
public:
    void display() {
        tot = (m1 + m2 + sm);
        avg = tot / 3;
        cout << "\n\n\tRoll No    : " << rno << "\n\tTotal      : " << tot;
        cout << "\n\tAverage    : " << avg;
    }
};
void main() {
    clrscr();
    statement obj;
