Well it was only pseudo-code, not really meant for use, just as
an example of what to do.

If you put it here, the players will only see the map when they change
rooms. Try act.informative.c look_at_room()

As I already said, the code was not complete, just an example....

You only need 4 not 5

if the "&n" is at the end of all of them, why put it there?
why not just initalize all the values of the map array to "&n"?
  char *sect_sym[] = { "&R*" };
  for (i = 0; i < MAP_ROOMS; i++) {
     map_rnum[i] = 0;
     sprintf(map_chars[i], "&n");
  sprintf(map_char[whatever_room], sect_sym[ROOM_SECTOR]);

This way, no matter what, every room will have a color code preceding
it's symbol, and no symbol will have the wrong color.

  Like i said, this really should be put into a separate function that has
this inside of a for() loop(check for doors, etc). Then this function calls
that function from another for() loop(go through all exits of a room). Then
this function should be called from another function that calls this one in
a specific order from a for() loop( ie: run this function first on the
room, then the room to the north of the center, then the room to the east,
the room south, then west, the the rooms to the north, east, and west of
the room to the north.)

Easy enough, it can be put anywhere, just make sure you declare
the main function before you call it.

Use a buffer and a few sprintf's.

Oh, on a side note, if your mapping a city, you may want to work
with more detailed maps, like 3 chars by 3 chars on the map per
room, that way you can designate open/closed doors, and the map
doesn't look so clutered.
