WebMar 29, 2024 · My inital solution was: for (i = 0; i < ROWS; i++) { fwrite (&arr [i], 1, sizeof (unsigned short int), source); } The code above works when writing unsigned short ints to the file. Also, source is a pointer to the file which is being written to in binary format. However, I need to swap the bytes, and am having trouble doing so.
