C doesn't redefine the integers; it defines addition and subtraction
on pointers.  That is: if p is a pointer to element n of an array
and i is an integer, then p+i is a pointer to element n+i of that
same array.  If p is a pointer to element n of an array and q is a
pointer to element k of the same array, then p-q is an integer and
has the same value as n-k.  What is so confusing about that???
