Multiple Header Files

    9 August 2007, terribly early in the morning

When programming, related functionality should be grouped and declared in their own header files, with definitions of functions in their own source files. Dividing your source code neatly in this fashion allows code that requires this functionality to (ideally) #include just the definitions it needs, and no more. You should be able to look at the #include directives in source file and header files and understand the dependencies of the code contained within; you should be able to see the relationships between the functions in your program. If you are lazy about the file structure of your source this becomes difficult. Don’t be lazy.

Don't be shy, you can comment too!

Some things to keep in mind: You can style comments using Textile. In particular, *text* will get turned into text and _text_ will get turned into text. You can post a link using the command "linktext":link, so something like "google": will get turned in to google. I may erase off-topic comments, or edit poorly formatted comments; I do this very rarely.
