Я полностью застрял. Это моя неполная программа. Программа застревает в файле.at или определяет, является ли гласная линия. Мне нужен совет, чтобы исправить мою программу. Что программа должна делать взять текстовый файл, содержащий следующие строки:C++ fstream чтение и запись в файл
C++ Programming is fun Winter is here, will it ever end? The style requirements document is so useful Functions really make programming easier Spring must be coming soon... I wish this #$##$$!!## program was done What comes after C++, D--?
Я должен сделать некоторые расчеты и экспорт в файл, чтобы он выглядит в этой ссылке: http://tinypic.com/r/24fhbfb/5
Вот мой код до сих пор. Любые указатели на то, что я делаю неправильно, будут высоко оценены. Я должен выполнять все функции.
