[Tutor] More Function Questions (Joseph Q.)

[Lee Cullens]

I think your looking at it too literally Joseph.  Rather than any one 
example, think of a function as a block of code that is used in more 
than one place in your program.  The x + y block of code is just a 
simplistic representation, intended to illustrate without the 
distracting complications of a more involved algorithm.

Functions are also useful (even necessary) in various approaches to 
problem solving.  If you need an example one might be the recursive 
matrix solution approach I posted a link to in another post to this 
list.
