One further note: int[][] is not valid C in parameter types. Only the first
[] can be without length, and is equivalent to a pointer. So char*argv[] is
the same as char**argv. Valid parameter type examples: int a[][3], int
b[][2][3]. These are like int(*a)[3] and int(*b)[2][3] if I am not mistaken.
