Section 27:
[27.1] What are some good C++ coding standards?

Thank you for reading this answer rather than just trying to set your own coding standards.

But beware that some people on comp.lang.c++ are very sensitive on this issue. Nearly every software engineer has, at some point, been exploited by someone who used coding standards as a "power play." Dogmatism over minutia is the purvue of the intellectually weak. Don't be like them. These are those who can't contribute in any meaningful way, who can't actually improve the value of the software product, so instead of exposing their incompetence through silence, they blather with zeal about nits. They can't add value in the substance of the software, so they argue over form. Just because "they" do that doesn't mean coding standards are bad, however.

Another emotional reaction against coding standards is caused by coding standards set by individuals with obsolete skills. For example, someone might set today's standards based on what programming was like N decades ago when the standards setter was writing code. Such impositions generate an attitude of mistrust for coding standards. As above, if you have been forced to endure an unfortunate experience like this, don't let it sour you to the whole point and value of coding standards. It doesn't take a very large organization to find there is value in having consistency, since different programmers can edit the same code without constantly reorganizing each others' code in a tug-of-war over the "best" coding standard.

Obviously anyone who asks this question wants to be trained so they don't run off on their own ignorance, but nonetheless posting a question such as this one to comp.lang.c++ tends to generate more heat than light.

For an excellent book on the subject, get Sutter and Alexandrescu, C++ Coding Standards, 220 pgs, Addison-Wesley, 2005, ISBN 0-321-11358-6. It provides 101 rules, guidelines and best practices. The authors and editors produced some solid material, then did an unusually good job of energizing the peer-review team. All of this improved the book. Buy it.
