this code work before, i work in school copied it to hotmail.com and send it to myself. But when i get back home and copy and paste and run, it give me an error call "Mac file format detected: pelase convert the soiurce file to either DOS or UNIX format. that shouldn't be becuase the school computer are all windows and we use the exact same visual c++ 2008
