    }
   Marks( int im,int em){
    intmark =im;
    extmark = em;
    }
    void display(){
    cout << intmark<<endl<<extmark<<endl;
    }

    Marks operator+(Marks m){
        Marks temp;
        temp.intmark = intmark + m.intmark;
        temp.extmark = extmark + m.extmark;
        return temp;

    }


};

   Marks m1(10,20),m2(30,40);

   Marks m3 = m1 + m2;
