If you think about it for more than ten seconds you realize that an iterative function using a for loop does the job just as easily. The overhead of the recursive calls seems to be nothing but a waste. Second, it gives no hint as to the power of the concept of recursion; instead it trivializes the concept.

After studying this example you might come away thinking that recursion has about as much power as looping; that a recursive function just seems to be another way of implementing a loop. Instead of giving you a glimpse into the power of this programming concept, it leaves you with the impression of a trivial variation of something you already know. Finally, there are other, better examples of recursive functions out there that are not much more complicated than factorial.

If you are serious about teaching recursion, you can do better than the factorial program. You are commenting using your WordPress. You are commenting using your Google account.
