How to display in columns

[Jody]

Help! I've written the following program but am having problems with the display I'm trying to get. I want the user to be able to enter 5 dates. AFter entering 5 dates, I want the program to display 5 columns showing the following:
Col 1 (date entered), Col2 (Euro date), Col3 (Julian date), Col4 Military Date), and Col5 (Business date). I'm struggling trying to figure out how to get this accomplished. I am a BEGINNER and don't know much!
