Ok, I've been having what I thought would be a simple problem but no one
seems to quite figure out. I Have an array of strings, both the key and
the string being pointers. Putting information onto the array is like a
stack.  My problem comes in the removal of information from it. Popping
from a stack only pulls the lastelement out of the array, I want to pull
any element out. Destroying the data isn't the hard part because I just
blow up the pointers...the problem is that the indexing for the array
gets kind of screwy. If I have an array organized by integers with
elements 1 2 3 4 5 6 7 8, if I decided to kill element #4 I'm going to
have an array of 1 2 3 5 6 7 8, and as time goes on its going to get more
screwy. Is there an easy way to delete an element while preserving some
semblance of sequence in the array indexing? In Perl I'd use the splice()
command...is there anything similar in C/C++?

I get the feeling I'm looking at this from a completely wrong
perspective, so don't flame me if I am...

Thanks.
