You should track this when you create the array.
Again, the array size is *not* dynamic. If you create a size 15 array
of ints, it will always, always, always contain 15 ints. Just becasue 4
of them aren't used values doesn't mean they don't exist. Basically, an
array is just a contiguous chunk of memory space big enough to hold your
data plus some metadata (specifically the datatype) to help it with
pointer math. You could do the same thing with malloc() and a couple of
variables.
In CF, arrays act a whole lot like linked lists, which confused the crap
out of me at first. If you need this kind of functionality, you can
either write your own LL or use the generic template in the STL.
If I'm going over your head, let me know and I'll explain anything you
don't get. If you want to know more, just ask.
If you want to take this offline, that's fine, too.
