Undefined behaviour; see the FAQ. (You write to the same location,
`a`, /three/ times in a single complete expression; that's
explicitly undefined behaviour. Even if it were not, what makes
you think that your idea of order-of-execution and the compiler's
have to be the same?)

Yes, but the front page, <http://www.c-faq.com/>, says:

[Note to web authors, catalogers, and bookmarkers: the URL
<http://www.c-faq.com/> is the right way to link to these
pages. All other URL's implementing this collection are subject to
change.]

When I cite the FAQ, I always provide the URL for the front page and
the question number rather than the URL of the specific question, both
for the reasons stated above and because it encourages readers to
browse the rest of the FAQ.
