CS 131        ASSIGNMENT 9      

Write a program that will accept as user input data a year and the day of 
the week on which January 1 falls and will print a calendar for the year.  

You must use EXACTLY the following functions:

void print_month(ofstream& fout, int month, int& day)
// Write the calendar for a month.  
// The first parameter is the number of the month (1 to 12). 
// The second  parameter is the day of the week on which the month starts (0 to 6).
// It is updated to return the day on which the next month starts
  
int days_in(int month)
//return the number of days in month (int is an integer between 1 and 12)


Step 1: Write a top-level program which prints the year, and calls a 
stub for print_month.  

Step 2 (10 points):  Fill in the body of print_month so that it prints the  month 
and day headings, but no days:

                                2007

                              JANUARY
                        S  M  T  W  T  F  S

                              FEBRUARY
                        S  M  T  W  T  F  S

                                 MARCH
                        S  M  T  W  T  F  S
                                ...
                                   

***************DO NOT THINK ABOUT STEP 3 UNTIL STEP 2 WORKS*****************
Step 3 (13 points):  Write the complete calendar. 


* (2 points) Modify your program so that it takes into account whether 
or not the year is a leap year. A year is a leap year if it is divisible
by 400 or a year that is divisible by 4 and not divisible by 100. For 
example, 1900 is not a leap year, but 2000 is.
