Because this program does not provide a feature to flag unprobed cells manually, we can do nothing if the number of unprobed cells are equal to the number of mines remaining; unwinnable.txt is an example for such a case. Thus, I implemented an additional rule to flag all unprobed cells in such a case into the final version (prog.c).
