    cout <<endl;

    display(anil);

    return 0;
}

void display(student s){
    cout << s.rollno <<endl;
    cout << s.sex <<endl;
    cout << s.age <<endl;
    s.rollno = 0000;
}

void show(student *s){
    cout << s->rollno <<endl;
    cout << s->sex <<endl;
    cout << s->age <<endl;
    s->rollno = 0000;
