     You seem to have a basic understanding of what they are.  Yeah, they 
just point to a certan spot in the memory, but they have a lot of 
advantages.  For one, they can point to an array or something, so they don't 
have to be just one object (kind of).  Also, they can just have a block of 
memory allocated (via malloc(...) or new).  This greatly improves the 
flexibility of C++.  This doesn't explain it too well, but I hope it helps a 
little.
