Ошибки:

ошибка C2664: ‘errno_t strcpy_s (char *, rsize_t, const char *)’: невозможно
преобразовать параметр 2 из «char [512]» в «rsize_t»

ошибка C2664: ‘errno_t strcpy_s (char *, rsize_t, const char *)’: невозможно
преобразовать параметр 2 из «char [512]» в «rsize_t»

IntelliSense: ни один экземпляр перегруженной функции «strcpy_s» не соответствует
список аргументов
Типы аргументов: (char [512], char [512], int)

Я пытался решить эту проблему. Пожалуйста помоги.
