This article is Copyright 1990-1999 by Steve Summit. Content from the
book _C Programming FAQs: Frequently Asked Questions_ is made available
here by permission of the author and the publisher as a service to the

Certain topics come up again and again on this newsgroup. They are good
questions, and the answers may not be immediately obvious, but each time
they recur, much net bandwidth and reader time is wasted on repetitive
responses, and on tedious corrections to the incorrect answers which are
inevitably posted.
This article, which is posted monthly, attempts to answer these common
questions definitively and succinctly, so that net discussion can move
on to more constructive topics without continual regression to first
principles.
No mere newsgroup article can substitute for thoughtful perusal of a
full-length tutorial or language reference manual. Anyone interested
enough in C to be following this newsgroup should also be interested
enough to read and study one or more such manuals, preferably several
times. Some C books and compiler manuals are unfortunately inadequate;
a few even perpetuate some of the myths which this article attempts to
refute. Several noteworthy books on C are listed in this articles
bibliography; see also questions 18.9 and 18.10. Many of the questions
and answers are cross-referenced to these books, for further study by
the interested and dedicated reader.
If you have a question about C which is not answered in this article,
first try to answer it by checking a few of the referenced books, or by
asking knowledgeable colleagues, before posing your question to the net
at large. There are many people on the net who are happy to answer
questions, but the volume of repetitive answers posted to one question,
as well as the growing number of questions as the net attracts more
readers, can become oppressive. If you have questions or comments
prompted by this article, please reply by mail rather than following up —
this article is meant to decrease net traffic, not increase it.
Besides listing frequently-asked questions, this article also summarizes
frequently-posted answers. Even if you know all the answers, its worth
skimming through this list once in a while, so that when you see one of
its questions unwittingly posted, you wont have to waste time
answering. (However, this is a large and heavy document, so dont
assume that everyone on the newsgroup has managed to read all of it in
detail, and please dont roll it up and thwack people over the head with
it just because they missed their answer in it.)
