An interesting problem! :-) Given a telephone book sized list of model numbers, write an is_in_telephone_book(char const *s) function that is significantly smaller than the strings for the model numbers. If you don't want to simply use a (compressed) table of the entries, then you'd better start by writing test code to prove that there are no false positive or false negative matches. Bruce
