This is a wild one: can anyone write a code that converts a number into the corresponding word? e.g.:
4 -> 'four' 31 -> 'thirty-one'
and so on. Obviously, it is not enough to build an array in which you can store the numbers and the word associated with it and then just print instead of the number the stored word. What complicates matters more, are numbers like 11 ('eleven'). I intend to use it for numbering equations. So, anybody up to it?
