Cool,
This contest is getting interesting. I hope all goes well!
P.S. I can't Edit my posts after a while, so anyone that participates in the contest will be added to my signature. Once the contest is over, I will post all the contestants names and of course the winner.

Segmentation Fault: I am an error in which a running program attempts to access memory not allocated to it and core dumps with a segmentation violation error. This is often caused by improper usage of pointers, attempts to access a non-existent or read-only physical memory address, re-use of memory if freed within the same scope, de-referencing a null pointer, or (in C) inadvertently using a non-pointer variable as a pointer.
I would like to try and come up with something.
How might I go about obfuscating c++ code?? just stick in a bunch of dumb symbols or what?
Hello,
cerin: By obfuscating code, you literally take a normal piece of code and make it harder to understand. Literally by using #define to make code look less presentable with type shortcuts, etc... Maybe this link could help clear some things up.
Loctan: Sure. Everyone is welcome to join in!

I'll give it a shot. Sounds like fun.
Can you intermix languages as long as it can all be compiled by a standard C compiler?

i don't think most standard compilers support programmers with more than 4 red boxes - Misplaced
It is my sacred duity to stand in the path of the flood of ignorance and blatant stupidity... - quzah
Such pointless tricks ceased to be interesting or useful when we came down from the trees and started using higher level languages. - Salem
Hello,
andyhunter: Yes. As long as it works on any C/C++ compiler, i.e. gcc. If you include any special libraries, please state which ones. If you use any special gcc or other compiler flags, please state that also.
linuxdude: Cool!

Sorry but that doesn't help me much because I c++ and have no programming background. Heh heh, sorry for the trouble.
No problem,
Take for example the following code:If I asked you what it does, I would probably get a dumbfounded look. If I told you this program solves the n-queens problem with chessboard output, would you believe me? That is obfuscated code. There is no telling what it does, and it is difficult to reverse engineer such code. This code may be easy to reverse engineer, but in practical size source code I would have to think twice.Code:#include <stdio.h> int v,i,j,k,l,s,a[99];main(){for(scanf("%d",&s);*a-s;v=a[j*=v]-a[i],k=i< s,j+=(v=j<s&&(!k&&!!printf(2+"\n\n%c"-(!l<<!j)," #Q"[l^v?(l^j)&1:2])&&++ l||a[i]<s&&v&&v-i+j&&v+i-j))&&!(l%=s),v||(i==j?a[i+=k]=0:++a[i])>=s*k&& ++a[--i]);printf("\n\n");}

Count me in
Boy you stink, go take a shower before you continue to code. Better do your laundry and spray your chair too.
The one and only resource for finding information.
Next version of windows released!!!!
the past 28 years of my life have been obfuscated.. does that count for anything towards this contest..

If I did your homework for you, then you might pass your class without learning how to write a program like this. Then you might graduate and get your degree without learning how to write a program like this. You might become a professional programmer without knowing how to write a program like this. Someday you might work on a project with me without knowing how to write a program like this. Then I would have to do you serious bodily harm. - Jack Klein
I'm in too
If you understand what you're doing, you're not learning anything.
Awesome,
12 running contestants as of now. Keep 'em rolling!I've received a few submissions already. It's showing promise.
P.S. I will compile all submissions on Windows, .Net 2003 & Dev-C++ 4.9.9.0, and Linux, gcc / g++ 3.2.2, 3.3.2, and 3.4.2. Red Hat 9, Mandrake 10.0, and FreeBSD 5.3. Good luck!

I'm up for it too!
I've never done the obfuscated thing before, but I'll have a crack at it.
