    Introduction
    Obfuscated code is source code that is very hard to read and understand. Some languages are more prone to obfuscation than others. C, C++ and Perl are most often cited as easily obfuscatable languages. Macro preprocessors are often used to create hard to read code by masking the standard language syntax and grammar from the main body of code.

    Obfuscated code has its advantages and disadvantages. For instance it minimizes code size though, however, is extremely difficult to debug.

    Details
    Create a Hello World program using obfuscated code. Your code will be judged not based upon code size, but rather your creativity.
    Bonus [5 points]: Explain your obfuscated code in detail. For instance, what block of your obfuscated code executes which part your program.


    Contest Rules
    Below are the current contest rules and regulations.

    I. Official Rules
    I.I You may only submit one entry per contest, and it must have been submitted between the contest start and end dates.

    I.II Entries submitted should be:
    • Substantially the developer's original design
    • Substantially the developer's original programming
    II. Code Judging
    II.I Submitted code will be judged based on the following:

    Compiliation (0 - 5)
    How easy it is to compile. And if it compiles on multi-platform.

    Ingenuity (0 - 10)
    This will be graded depending upon if you have created this code yourself, or have used other sources to compile your code.

    Efficiency (0 - 5)
    Code efficiency, how can it be used in a program. Is it usable or just fancy. (Are processes closed when finished, do you use arrays when initializing multiple variables under one instance, and do you free memory after allocation?)

    Best Code Score: 20

    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.

    IMO obfuscated code contests are better if all the program entries have the same end result. IE the 12 days of christmas contest from 2003

    I agree,

    In this case, I have changed the contest slightly. Everyone is now to write a Hello World program using obfuscated code. The obfuscated code can be short or long. Remember, the code is judged by creativity none-the-less.

    What do you mean by hello world just a simple hello world to the console or just like a rudimentry app? eg. add two numbers, fahrenheit to celcuis etc..

    Hello,

    prog-bman: By "Hello World!" I mean actually coding it as obfuscated as possible. Enough that you wouldn't even realize it produces and prints Hello World! until executed.

    Edit: I'll keep this contest a bit simple for now. I might make a Part 2 later with more advanced techniques. Besides, I want to see how obfuscated something as simple as Hello World can be.

    CornedBee: Let the games begin!

    How might I go about writing obfuscated code? I don't exactly understand how to make it hard to read.

    Can we assume that all OS's you will try the code on use ASCII system??

    Does it have to print the literal string "Hello, World!" or does something that can be read as it (ASCII art) suffice?

    cool contest.. i'm in


    I think the fun part would be seeing everyone's ideas when the contest is over.

    Hello,

    To answer your questions:

    Obfuscated code, for instance, looks like this in general. To best describe Obfuscated code, I would say it is a "concealment of evidence" and harder to "reverse engineer".

    Well, as of the moment, I believe the answer is yes. Just use standard C functions and calls and it should compile without a problem on any C compiler.

    It can be done either way. ASCII art is cool, and I would definetly have to give extra bonus points for that.

    Sounds like a good idea. This way we can all see multiple ways to making a Hello World program.
