Well, I personally like ++argv best, but the argument above is just NOT TRUE!
Referring to K&R page 94:

    int *pa

    . . .

    The definition of "adding 1 to a pointer", and by extension, all pointer
    arithmetic, is that the increment is scaled by the size in storage of the
    object that is pointed to.  Thus in pa+i, i is multiplied by the size of
    the objects that pa points to before being added to pa.
