   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;



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

   Marks m3 = m1 + m2;

    return 0;
