Chapter 6, Exercise 6

[CloudDweller]

Okay this one took me ages and I mean ages.  My first attempt can be found here http://classroomm.com/objective-c/index.php?topic=6714.0

and as you'll see it took me a while to get my head around it.  All I can say is that if you stick at it, you'll get there in the end and if not, re-reading chapters really helps to cement stuff and if you're still stuck there's plenty of help available in these forums.

Thanks again Steve 

Code: (Objective-C)

        for (; counter > 0; counter /= 10) {                        // while counter is greater than 0 execute the loop and then divide counter by 10
