Перенос исходного кода из Assembler на C++
25.10.2017, 15:49. Показов 1474. Ответов 4
Доброго времени суток форумчане!
Столкнулся с проблемой переноса кода на C++. По заданию, имеется исходный код на языке Assembler. Необходимо
перенести исходный код на C++. В результате, должна получить программа использующая WinAPI, отрисовывающая
окно, и несколько линий.
В принципе код я перенес, компиляция происходит без ошибок, однако окно не появляется. Подозревал что не правильно
отрабатывает функция создания и показа окна, но видимо это не так
