У меня проблема. Я пишу программу, которая читает и записывает матрицы, векторы и скаляры, но у меня проблема. Это мой код zaliczenie_ c. c

При компиляции вот так

Все ок.
Вдобавок . Моя программа показывает результаты на экране очень хорошо, но моя программа не записывает в файл (fprintf), и я не знаю, почему
