I was starting to get annoyed by the whole AUC thing instead of real years, and I was too lazy to constantly do the math to convert. So I made a little program in C++ to convert the years for me. It works, and its helping me learn C++. Win-win. I thought I'd upload it here in case anyone else wanted it.
Here's the code too.
UPDATED! Now does the opposite as well, from Gregorian to AUC.
Here's the new code.
SECOND UPDATE!
I have fixed a few stupid mistakes in my code from the second version. I suppose I should call this version 2.1. Be sure if you want this to download this one. It was giving the wrong date whenever you tried to convert a date in AD. Really should've debugged a bit...
