I would have to disagree with chris as to what should be assigned by:
	char *in, *out, buf[];
	in = buf;
	out = &(*in++);
since he forgot the parentheses.  Given the parentheses, out SHOULD
be set buf+1; that is, 'in' is incremented BEFORE the & operator is
applied.

(The original article did not include the second line of my example,
and asked whether out should be set to 'in', or 'in+1'.  The answer
is of course 'in'.  The question is not meaningful as stated.  The
question should be: does it point to the ORIGINAL value of 'in', or
the incremented value of 'in'.)

Yes, but the & operator is not being applied to `in', but to `*in', with
the increment happening AFTER the dereference. Therefore, you should get
buf, not buf+1.
