Greg, Hm... Do you think it would be better to use a right-to-left approach?

The programming in the number to text problem IS really quite trivial. The difficulty, as with most programming tasks, lies in the ability to break the problem down into smaller solveable pieces. Ironically enough the pieces which do, indeed, make sense were stated in the problem description. For example... Decide how you would solve the problem of naming a number between 1 and 999. Once you have this solution the same algorithm can be used for each subsequent group of 10^3 digits (thousands, millions, billions, etc.). Note that this is exactly the reasoning that you go through when you decide how to read the number. For example, you know that for 123 numText = "one hunbred twnty three". When it happens to be that the "123" text is in thousands positions..123,XXX you simply append thousand to numText, etc. Break the problem down. Similar reasoning can be used to solve the hunreds digit as well.

I am trying to grasp these problems on my own AND I AM NOT GETTING GRADES FOR THIS. I am merely trying to understand what an approach can be taken toward these problems. I do not know how to do them myself and they, I am told are in fact for more advanced programmers while I am just a beginner level programmer. So on that basis, can I ask if you could kindly help with these ? ----- Original Message ----- From: "Joseph Ottinger" <[EMAIL PROTECTED]> To: "JDJList" <[EMAIL PROTECTED]> Sent: Wednesday, September 25, 2002 8:42 PM Subject: [jdjlist] Re: two exercises I am trying to solve at the moment.... > >From: "Tim Nicholson" <[EMAIL PROTECTED]> > >Subject: [jdjlist] Re: two exercises I am trying to solve at the moment.... > > > >Are you saying that you actually got programming questions when you were in > >grade 9 ? > > Yeah.
