Compile this:
-
i don't compile things unless i know exactly what they do, i like my system as it is and i don't want to do anything that would hurt it. besides, if its in my power, i only compile code that has good explaination for what it is doing.
-
Heh heh.. well you don't have to worry about this one. You won't believe what it does when you compile and run it. Besides, can't you read the source? (http://smile.gif) This is actually an example of an entry in the obfuscated code contest. I ran across it many years ago and it's still my favorite. It has to do with Christmas... Besides, if you compile and run it as a normal user in Linux what can it do? Again, I only mess with Windows users, not Linux users so this one is safe.

how do i compile it?
$gcc filename.extension?
-
Just copy/paste the quoted code into a file with a *.c extension. Then "gcc filename.c" which will create a program called "a.out". To run it type "./a.out", actually you might want to pipe it through "more" like this:
./a.out | more

Then you must not have copy/pasted it properly. I copy/pasted it into a file (and removed the leading white space before each line that somehow appeared in "vi" where I pasted it to). It compiled without a single error or warning message. In case you were wondering what the output of the code is, it's:
-
im stupid, i used emacs on FreeBSD and entered and it compiled, one question HOW, and WHY, i know is an obfustaction/*i can't spell*/ contest, but could you imagine maintaing that kinda code????
-
I think you would be in the looney house after a few months .... lol
-
after i though about it, it wouldn't be to significgane of a c++ prog either, written in NORMAL c++

Well, this code was the 1988 ioccc winner (phillipps.c) which you can find here:
http://www0.us.ioccc.org/years.html (http://www0.us.ioccc.org/years.html)
An interesting article and disection of the code can be found here:
http://www.go2net.com/internet/deep/1997/01/08/body.html (http://www.go2net.com/internet/deep/1997/01/08/body.html)
About 8 years ago I remember seeing a much better disection of the code where it was properly indented out and translated into more appropriate C code. Still it was very difficult to understand but it was a good article. I can't seem to find it now though.
All I have to say is the guys who wrote it were genious, along with the other winners of the contest.
