Since char arrays are in Chapter 1 of K&R, I assume we can use them. Can we assume that identifiers won't be longer than 31 characters, thus allowing the use of char arrays (they have a maximum length since we can't use pointers) or can identifiers be of any length, thus requiring a different solution?
