Here we go again, warm up the flame guns...

Ok, suppose I have an array like
    char strings[NUMBER][SIZE];
How do I add more strings to this array, i.e. make it larger, portably and
easily.  I can't realloc it, since it's not a pointer!  Argh!  Is there some
sneaky way to declare it so that I can do what I want, or should I just use
    char *strings;
and a lot of pointer arithmetic?  How about
    char **strings;
    strings = (char **) calloc (NUMBER, sizeof (char *));
    strings[0] = (char *) malloc (SIZE);
    strings[1] = (char *) malloc (SIZE);
    ...
(I don't care if the 2d array is contiguous or not...)
Then strings is a pointer and I can realloc it, allowing me to add more
strings!  And can I even access them as
    (strings [string_num]) [string_pos] = 'x';
which becomes
    *(*(strings + string_num) + string_pos) = 'x';
or does it?  I'm not sure....
