How do you order your #includes at the top of a cpp file? You probably don't care, because it mostly doesn't matter. But, for whatever reason, I care. First the precompiled header header, of course. Then a linefeed. Then I like putting the matching .h file first, because if that .h file needs any other .h files, we'll immediately find out and can include them within that .h file.
Then another linefeed. Then the "" headers. Our headers. In alphabetical order. How anal is that? I guess I like structure. But it does have one little advantage, that you won't accidentally include the same file twice. Not that that matters, either, but it does look a little bad if someone sees it. Then the standard lib <> includes.
Just thought I'd share. This isn't something I ask coders on my projects to do, but when I'm working with their files, I sometimes go in and rearrange their headers to suit my whims.
