incrementing

Here's something few people know about C: pointer arithmetic scales integers by the size of the type being pointed to. For example, if ptr is a pointer to an int, then ptr++ will add 2 (or whatever the native size of an int is for a particular target). If parr is a pointer to a structure of twelve bytes, parr = parr + 3 will add 36.

But don't abuse this fact. Pointer arithmetic is not necessarily something useful for programming PIC processors to control FRC robots.
