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

In embedded systems, pointers are used to represent addresses or locations. There may not be an array defined. (Although one could say that all of memory is one huge array.)

For example, a stack (holding variables and addresses) is manipulated by adding or subtracting values from the stack pointer. (In this case, the stack could be said to be an array based stack.)
