# print_month.cpp

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]
