Help with generating a calendar

jak1098 (6)
Problem:
Write a program to generate a calendar for a year. The program should accept the year and the day of the week for January 1 of that year (0 = Sunday, 1 = Monday, etc.). The calendar should be printed in the following form:

January
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 29

30 31

February
1 2 3 4 5

I have wrote code that has three functions, one to print the month, one to print the days in month, and one to find if it is a leap year or not. I have gotten up to the point where I can print the 12 months with a for loop, but I have no idea how to print out the days in the format above. Can anyone help?

This is my code(sorry for any confusion I just started a couple months ago).

You'll also need to know the day of the week that the first falls on for each month.

http://www.faqs.org/faqs/calendars/faq/part1/index.html
See 2.6 for the algorithm.

By the way, the days in a month follow a pretty simple pattern:

if month is February: days is (28 + is it a leap year?)
else if month < August: days is 30 + is month odd?
else: days is 31 - is month odd?

Good luck!
