Does pointer arithmetic have uses outside of arrays?

Question

I think I understand the semantics of pointer arithmetic fairly well, but I only ever see examples when dealing with arrays. Does it have any other uses that can\'t be achie

Answer 1

From the top of my head I know it's used in XOR linked-lists (very nifty) and I've seen it used in very hacky recursions.

On the other hand, it's very hard to find uses since according to the standard pointer arithmic is only defined if within the bounds of an array.
