Programming assignment

Write a program that takes as input two numerals representing a month (January is represented by 1) and a year, and then prints a calendar for the month in the year specified.

• If 1 <= month <=12 and year >= 1 then the calendar is displayed with the name of the month and year on one line, the days of the week below, and finally the layout of the days of the month. For example if the input were 2 2006, then we expect output similar to the output of cal on a Unix system:

 
 February 2006
 S  M Tu  W Th  F  S
          1  2  3  4
 5  6  7  8  9 10 11
12 13 14 15 16 17 18
19 20 21 22 23 24 25
26 27 28

• If month <1, month > 12, or year <= 0 then output the following:

 INVALID INPUT 
 X X X X X X X
 ? ? ? ? ? ? ?
 ? ? ? ? ? ? ?
 ? ? ? ? ? ? ?
 ? ? ? ? ? ? ?
 ? ? ? ? ? ? ?

• Note that the formula on page 415 should be dayOfWeek =int(JDN +1.5) %7 according to the information at http://mathforum.org/library/drmath/view/54374.html. Alternatively you can change the constant in the formula on page 416 to 1720994.5. It has the same effect.
• I'm expecting to see the program contain at least five functions:
• A function that returns the name of a month given the month number
• A function that returns a numeral indicating the day of a week on which a date occurred/occurs given the month, day, and year as input.
• A function that returns True if a year is a leap year and False if not.
• A function that returns True if the input is valid and False if not.
• A function that prints a calendar for a month and year. The program verifies the month and year are valid, before the function is called.
• Input comes stdin. Output goes to stdout. No prompting for input, and no output other than what is specified above.

Assignment is Due Wednesday, March 15, 2006. Deliverables:

• A completed project analysis: It’s always best to put thought into the design of the project BEFORE you begin typing. For this assignment you re required to complete a project analysis before the assignment is due. The project analysis is due March 1, 2006, with 5 points deducted from your total score for the project for each day it is late. To complete the project analysis sheet, copy the file: ~ernie/220/prj2.txt. Read through the questions and write appropriate answers for your program.
• A link to the source file
• A link to a script file showing the compilation and execution of the program
• A link to a file containing the results of running your program with the following inputs.
