wtf is a quine???

:quine: /kwi:n/ /n./ [from the name of the logician Willard van Orman Quine, via Douglas Hofstadter] A program that generates a copy of its own source text as its complete output. Devising the shortest possible quine in some given programming language is a common hackish amusement.

last fun coding trivia of the night, but LOOK at some of this code... it's f'in awesome.

One day, several years ago, I came across an article in an old Byte on "self-reproducing programs".

Self-reproducing programs? Kinda sounds like a worm to me...

Self-reproducing programs (aka: quines) are programs that, when run, output their source code. Nothing at all like viruses or worms.

Wow.. that is sweet. Now if only I could understand how to do it.

WORD. Breakout and Pac-Man were my favorites. I had a scaled down version of Street Fighter II with only Ken, and Ryu as characters, AND you could play with 2 people using that link cable thingy.

Code:

#!/usr/bin/perl

open A, "<$0";

while (&lt;A&gt;) { print; }

Is it cheating to use an interpreted language, pick up your own script file and print it? That's a pretty short quine! And it's embeddable! Stick it in ANY Perl script to turn that script into a quine.

I've just invented the Universal Quine! There's a PhD somewhere with my name on it!

ratbastid, I'm fairly sure that the PhD with your name on it stands for "Piled high and Deep" :D

ratbastid, I thought you'd come out with a Perl quine... but that has to be cheating... ;)

Here's a quine in C:

Quote:

char*f="char*f=%c%s%c;main()
{printf(f,34,f,34,10);}%c";
main(){printf(f,34,f,34,10);}

Here's a polygot quine in C and TCL(works in both)

Quote:

#define set char*f=
#define F
#define proc main(){
set F "#define set char*f=
#define F
#define proc main(){
set F %c%s%c;
proc /* {} {}
puts -nonewline %cformat %cF 34 %cF 34 91 36 36]
set a {*/printf(f,34,f,34,91,36,36);}
";
proc /* {} {}
puts -nonewline [format $F 34 $F 34 91 36 36]
set a {*/printf(f,34,f,34,91,36,36);}

There's a way to make a quine in any language that supports strings, search google if you want.
