Hello, I saw in one of the forums quite smart riddle: You should write a program which writes itself. This question and answer raised in very interesting article. If you want the article just ask but first- try to answer it by yourself.

Programs that write themselves out are called quines, and there have been several of them out there for almost any language.

Quines are pretty straightforward in most languages. Write a program that prints a string twice, make the string the same as the code, and tweak it a little.

More information on quines is available from Wikipedia. It has two sample quines written in both C and BASIC.
