Hi Tom,

Just a point need to clarify for above example:

You might want to move the default: break;  part to join up with cases
1, 2 and 3...  Note that in that example, if the program execution
reachs that point, no output is actually processed, BUT the function
will return (len) anyway.

Or you might want to write your own implementation at all.
