Если заявление ведет себя странно. По какой-то причине, если в операторе IF if ( choosePositionX ) переходит к другому, который сообщает пользователю, что другой игрок уже сделал ход, он переходит к следующему, если if ( choosePositionO ), и распечатывает остальное в этом. Как я могу сделать это так, как только он переходит к другому в любом случае, если утверждение, что оно просто вспыхивает и продолжается вниз. кажется, что break; не работает.
По сути, else в первом, как только он используется, переходит к секундам else во втором операторе if. Почему?
