--------------------
It is dangerous to increment pointer yourself (e.g. p = p + 4).
By doing so, you are restricting your programs to a specific machine type
since wordsize varies among diffenent machines. (a act against portability)

I don't have my K&R handy, but I thought that adding an int to a pointer
was defined to scale the int appropriately.  There is nothing special
about auto-increment in this regard.
