В принципе можно только вряд ли памяти не хватает... Дело в том, что до того как я стал выделять память в основной программе для Макс и Мин (до этого память выделялась в функции) все работало... но вот понадобились эти значения дальше по ходу программы и я решил получать их так же как до этого получал значения массива d в функц. ReadTXT (выделяю память - отдаю указатель в функцию - там получаю значения)...
Прилагаю код основного файла и файла с функциями. Вообщем проблема в обработке кнопки "Обучение" | C++ | 1
| if (LOWORD(wParam)==1) //Обучение |
