There are many style guides around the web talking about the coding best practices. Some guidelines are very interesting, some others are not suitable even they are recommended by known organisations.
CoderGears just launched the C/C++ Coding Best Practices Repository http://www.codergears.com/QACenter to centralize the most known best practices.
The goal of the repository is to vote and comment the C/C++ coding best practices rules to have the most interesting ones and every C/C++ developer will focus more on the most voted rules.
