In computing, a quine is a program (a form of metaprogram) that produces its complete source code as its only output. For amusement, programmers sometimes attempt to develop the shortest possible quine in any given programming language.
Quelle char*f="char*f=%c%s%c;main(){printf(f,34,f,34,10);}%c";
main(){printf(f,34,f,34,10);}
