Date constructor

when i initialize zot with this date: 10,9,2002...it only picks up the month...10...but gets junk for the rest ....why do u think that is the case??

Thanks!

=======================

Date::Date(int mon, int day, int year):julianDate(0)
{
      bool result;
      result = isValidDate(mon,day,year);
      if (result == 1)
      {
            month = mon;
            day = day;
            year = year;
      };
}

=====================

bool
Date::
isValidDate(int month, int day, int year)
{
      if (day < 1 || day > 31 || month < 1 || month > 12)
            return false;
      if (month == 2 && year%4 == 0 && day > 29)
            return false;
      if (month = 2 && year%4 != 0 && day > 28)
            return false;
      if (month == 4 || month == 6 || month == 9 || month == 11 && day > 30)
            return false;
      if (month == 1 || month == 3 || month == 5 || month == 7 || month == 8 || month == 10 || month == 12 && day > 31)
            return false;
      if (month = 0 && day == 0 && year == 0)
            return true;
      
      return true;
}

=====================

      cout << "\ninitialization constructor  Date zot(10,9,2002)";
      Date zot(10,9,2002);      // conversion constructor
      cout << endl
             << zot
             << " zot "
             << endl;
