Display a monthly calendar

Good Morning:
I need to write a function that displays the days of a specified month. I have been looking for sample code but haven't had much luck. Here are the guidelines for the function:

Write a void function named displayCalendarDays. This function is passed two input parameters. The first parameter is an int that represents the start day. Start days are numbered from 0 to 6 with 0 representing Sunday and 6 representing Saturday. The second parameter is an int that represents the number of days in the month. If the start day is not in the range 0 to 6 or if the number of days is not in the range 1 to 31, the program should display a helpful error message instead of displaying a calendar. If the parameters are OK, the program should display a calendar similar to the following:

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
After the last day of the calendar is displayed, the function should advance the cursor to the next line.
Note that for the display above, the start day is 3 and the numbers of days is 31.

Can someone please help me with this? The posting format is off the month should start on wensday.
