Calendar Program

Nic Bonzani (3)
Hi,
So for my C++ class I am required to create a program that will "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.)" (problem statement) and I am completely stuck. Can anyone help me? I've posted what I have so far below:

This doesn't use all the nice code you have written but maybe you will get some ideas from it.
