Segementation fault (core dump) error?

Toasthat (25)
I just need to see what is causing the segmentation fault (core dump) error and for some reason I can't get the constructor to output the error message when the date is out of range for the month.

...an integer from 1 to 31 for the month? Thats a strange question to be asked.

It's that final else statement. The one after December that doesn't have an if. Program execution dies right there.

It looks like you should have used switch case there, and instead of a final "else", had the default be there? If you can use switch case that is.

In addition, your print function is expecting you to return a string, but you are only printing.
Printing is not the same thing as returning a string.

If you don't want to return anything, change the return type to void.
