I love this bit of code. It saved my butt in '99 when I had to implement searches for potential "Y2K" coding issues. Some where, collecting dust in CVS repository, probably saved on tape is some storage bunker, is a modified version of this that searched millions of lines of code for various potential "double digit year" issues. And this also taught me an elegant way to implement recursion in C, that I shamelessly used in interviews to look way smarter than I actually am.
