        cin >> birthday;
    }
    y = abs(birthyear - year);
    m = abs(birthmonth - month);
    d = abs(birthday - day);
    if ((birthmonth - month) == 0)
        if ((birthday - day) == 0 || birthday > day)
            m = m + 1;
            y = y + 1;
    cout <<"\n\n" << "---_You to '" << y <<"_---\n";
