Help with recursive implementation

[toby]

Hi, I am trying to make a program that you input a integer such as 1000000. Then the program will return a string that has inserted commas where appropriate into the integer. So the program would print out the following: 1,000,000.
I am trying to do this recursively because I am having trouble understand recursive implementation.
Help would be much appreciated.
Thanks.

To understand recursion you must first understand recursion. --some other guy

That sounds like an odd way to try to learn recursion when there are easier ways to do that. Towers of Hanoi was the method used in school to teach recursion, there is plenty of online documentation for that so just google it and you'll come up with something.
