You know what my pet peeve is? People trying to force camelCase/PascalCase in C/C++. Fuck. It's like they thought it would be a good idea to bring their shitty naming style over from Java or C# and fuck things up for real programmings. Ultimately, I blame Microsoft for Hungarian, which is the true root of this scourge.
It's fucking C or C++ people! Everything is lower case and underscores, with some exceptions for preprocessor macros or template parameters. When in Rome, you should walk like the Romans. Not like some fucking jungle monkeys from Africa.
