If you try and read source code provided on here by people who haven't used the good old code tags, you might like to give this a go.

From the site:
GC GreatCode is a powerful C/C++ source code beautifier designed for senior programmers.
It works under windows 95, windows 98, windows NT, windows 2000.
I'm not affiliated with it, btw! But I have used it, and find it excellent.

Anyone have or know of any other utilities like this?
