Здравствуйте! Программа должна работать с файлом *.pcx . Однако при линковке возникает ошибка, которая находится в пустой строке, следующей за последней сторокой кода. Используемая версия Студии 6.0. На более новых версиях всё отлично компилится и работает. Код прилагается. Посоветуйте пожалуйста как избавиться от такой досадной ошибки! | Код |
