# Print Month

Simple utility to print out days of the month with the days of a month. Demontstrates date iteration (date_time::date_itr).

      /* This example prints all the dates in a month. It demonstrates
       * the use of iterators as well as functions of the gregorian_calendar
       *
       * Output:
       * Enter Year: 2002
       * Enter Month(1..12): 2
       * 2002-Feb-01 [Fri]
       * 2002-Feb-02 [Sat]
       * 2002-Feb-03 [Sun]
       * 2002-Feb-04 [Mon]
       * 2002-Feb-05 [Tue]
       * 2002-Feb-06 [Wed]
       * 2002-Feb-07 [Thu]
