blackjack на с++ ОШИБКА

[yugik]

Всем привет. Пишу консольную игрушку "очко" или "BlackJack" на С++, программа компилится без ошибок, вроде бы все нормально и связанно, но при запуске прога вылетает, происходит ошибка на уровне отладки. Помогите найти где нужно исправить ошибку.

Ошибка:

Необработанное исключение в "0x00241809" в "blackjack.exe": 0xC0000005: Нарушение прав доступа при чтении "0x336b2ab0".
Первый этап обработки исключения в "0x00241809" в "blackjack.exe": 0xC0000005: Нарушение прав доступа при чтении "0x336b2ab0".

Написать прогу мне нужно до завтра, огромная просьба помогите кто сталкивался с подобніми проблемами.
Заранее спасибо!

Код зараза не влазит....в одно сообщение попробую впихнуть в два


Первая часть кода:

поставте галочку в Debug -> Exceptions -> Win32 Exceptions
там в списке код этой ошибки, галочку напротив C0000005 Access Violation
Тогда дебагер остановиться на строке в которой происходит эта ошибка. Она значит, что вы обращаетесь по адрессу, которого не существует. Чаще из за переполнения буфера выскакивает, или при общанию к указателям для которых не выделена память.
