I think there is some trade off depending on how often you want to search.
For example, if I seldom search, but add a bunch of items all at once
sorting just takes up a bunch of time when each item is added. In that
case I'd likely use a map instead with a hash. I've also found I can
search through like 100K items in a CObArray in a second or so ... so an
occasional search is not really that objectionable. However, if the
program is constantly searching then a better mechanism is needed of
Hashes always seem like a pain to me in that it's not always easy to get a
good hash key, and data tends to use a lot of extra memory to have enough
slots for a good hash key (although this can be mitigated somewhat).
A good sorted array will perform a look up when inserting an item rather
than resorting the entire list and I've found that to be a good approach for
Of course, it's always a trade off depending on your particular
