Write a "Hello world" program, without using a semicolon, in:

1. C (puzzle taken from here) -- takes a while if you've switched your mentality from C to Java (is that a hint or what?)
2. Java (a bit more thought and knowledge of language is necessary)

public static final int ZERO = 0x0;
private static int enum = ZERO;
public static final int FIRST = ++enum;
public static final int SECOND = ++enum;

This trick is due to catamount, an excellent programmer with whom I have an honor of currently working .

Ok, so you can have abstract as a method modifier in a Java interface, though it's redundant, as they're implicitly abstract. But I just accidentally discovered that an interface itself can be defined explicitly abstract. Why, Mr.Anderson?

WIBNI (wouldn't it be nice if) one could:

• ...switch, at will, between MS Windows style way (highlight, then perform copy action, saving the result to clipboard, then pasting) and X way (highlight copies, some other action -- like mouse middle button -- pastes, with no action required to save -- "copy" -- the highlighted portion, and thus the next highlighting replaces the previous contents of the clipboard).
