* [Google C++ Style Guide](http://google-styleguide.googlecode.com/svn/trunk/cppguide.html).
Too timid and reflects its 1990s origins.
[A critique from 2014](https://www.linkedin.com/pulse/20140503193653-3046051-why-google-style-guide-for-c-is-a-deal-breaker).
Google are busy updating their code base and we don't know how accurately the posted guideline reflects their actual code.
This set of recommendations is evolving.
Geared toward C++03 and (also) older code bases. Google experts are now actively collaborating here on helping to improve these Guidelines, and hopefully to merge efforts so these can be a modern common set they could also recommend.
