If your tutor asks you to convert numbers to words (i.e. 565 to a string "Five hundred and sixty-five") then you are not alone! Here is the simplest, most foolproof way to do it.
If your tutor asks you to convert numbers to words (i.e. 565 to a string "Five hundred and sixty-five") then you are not alone! This question gets asked here very frequently, so here is the simple, foolproof way to solve your problem. It shows the outline of how to do it, and it is then up to you to fill in the detail, comments etc. - otherwise every-bodies would look the same, and you might get caught for copying!
```        public static string ConvertToWords(int number)
{
switch (number)
{
case 0:
return "Zero";
case 1:
return "One";
...
case 568:
return "Five hundred and sixty-eight";
case 569:
return "Five hundred and sixty-nine";
}
throw new ArgumentOutOfRangeException("Number greater than infinity!");
}
```

I cannot remember who originally posted this coding gem, and I can't find it with a quick search, but if you know who did post it let me know and I will provide full credit.

The original version of this software was written by Smithers-Jones[^] in C++ and is available here[^] My thanks for the inspiration and the excellent work!

I am indebted to Luc Pattyn for pointing out the error in versions before V3.0 regarding the placement of a hyphen between the tens and unit digits. He correctly pointed out here[^] that numbers should not be written as "twenty one" but as "twenty-one".

V2.0: Credit for original version added - OriginalGriff[/edit]
V3.0: Corrected the hyphenation between the tens digit and the units digit - OriginalGriff[/edit]
V4.0: Link to the message of Luc Pattyn corrected - ProgramFOX[/edit]

Born at an early age, he grew older. At the same time, his hair grew longer, and was tied up behind his head.
Has problems spelling the word "the".
Invented the portable cat-flap.
Currently, has not died yet. Or has he?

 Reason for my vote of 5 Yep, that solution efficiently gets rid of any special case handling as any number now is a special case. Also this is extremely portable, e.g. to french (99 = quatre-vingt-dix-neuf)
 is this some kind of joke??? danny333 9-Oct-11 5:47
