Re: strange C code

Default will never be executed.
If the input is anything other than one, the output will be 2.

This could possibly be an attempt to use the run-through effects of a case
to start or resume a set of statements by omitting the break statement.

The default definition would be better off at the bottom.

Toby was right, this program should return a value...returning void is bad
practice.
