To verify your results, ./mmf0verify

Remember to only use stdout to print the days of the week [EX: fprintf(stdout, “Monday\n”)]. If stdout is used for anything other than the days of the week, the mmf0verify will say you have a mismatch for every year, even if you get the correct day when you run your compiled code. If you want to print something other than the days of the week, use stderr.
