Why does the standard C ++ library use all lowercase letters?


Just curious why the C++ standard library uses all lower case and underscores instead of camelCase or PascalCase naming convention.

Personally, I find the latter much easier to deal with when typing out code, but is there some kind of legitimate reason to use the former?

Main reason : To keep compatibility with the existing code, since they have done it with C also.
