C++ FAQ Celebrating Twenty-One Years of the C++ FAQ!!!
(Click here for a personal note from Marshall Cline.)
Section 27:
27.1 What are some good C++ coding standards?
27.2 Are coding standards necessary? Are they sufficient?
27.3 Should our organization determine coding standards from our C experience?
27.4 What's the difference between <xxx> and <xxx.h> headers?
27.5 Should I use using namespace std in my code?
27.6 Is the ?: operator evil since it can be used to create unreadable code?
27.7 Should I declare locals in the middle of a function or at the top?
27.8 What source-file-name convention is best? foo.cpp? foo.C? foo.cc?
27.9 What header-file-name convention is best? foo.H? foo.hh? foo.hpp?
27.10 Are there any lint-like guidelines for C++?
27.11 Why do people worry so much about pointer casts and/or reference casts?
27.12 Which is better: identifier names that_look_like_this or identifier names thatLookLikeThis?
27.13 Are there any other sources of coding standards?
27.14 Should I use "unusual" syntax?
27.15 What's a good coding standard for using global variables? New!
[27.13] Are there any other sources of coding standards?

Yep, there are several.

In my opinion, the best source is Sutter and Alexandrescu, C++ Coding Standards, 220 pgs, Addison-Wesley, 2005, ISBN 0-321-11358-6. I had the privilege of serving as an advisor on that book, and the authors did a great job of energizing the pool of advisors. Everyone collaborated with an intensity and depth that I have not seen previously, and the book is better for it.

Here are a few other sources that you can use as starting points for developing your organization's coding standards (in random order) (some are out of date, some might even be bad; I'm not endorsing any; caveat emptor):

Notes:

  • The Ellemtel guide is dated, but is listed because of its seminal place: it was the first widely distributed and widely adopted set of coding guidelines for C++. It was also the first to castigate the use of protected data.
  • Industrial Strength C++ is also dated, but was the first widely published place to mention the use of protected non-virtual destructors in base classes.
