Re: strange C code

What's so wierd about it?
the void main(void) is technically illegal -- you should always define main
as int main and return a value.

the switch(1) will only ever execute case 1, but that's not particularly
odd. Are you sure you didn't mean to ask what would happen if the switch()
was a switch(3) or something?
(ie. what happens if the default: case falls thru?)
