Ok, I think I have an answer for question 1...

Let's say I just happened to have an include file that defined a macro
like this

#define say(what) printf(#what "\n");

Then I write the hello world program as

#include "say.h"
void main()
{ say(Hello World!) }

Kind of cheating since the macro has a semicolon in it but the program source
itself doesn't.

BTW, my first attempt wasn't quite geeky enough, this is actually better
(in terms of being even less readable :-)

int dispnum ( int num )
{
printf("%d\n", (num>0) ? num : -num);
return((num > 0) ?
    (num=(num < 100) ? dispnum(++num) : dispnum(-num)) :
    (num=(num < -1 ) ? dispnum (++num) : 0 ));
}

void main()
{
dispnum(1);
}

Well... it's a nice day here in Albuquerque so I'm going to go enjoy it now
that I can't remember why I logged on in the first place. It might have had
something to do with "work" I need to catch up on but this was more fun.
