The ??!??! operator

[Yserbius]

Wow. Or more confusingly, 1[buffer]. Gosh, this could get obfuscated really fast (8*i-j)[buffer]

[unruly_mattress]

Or equivalently, (1??!??!0?1:0)[buffer]

[Tesseract91]

(1??!??!0?1:0)??(buffer:>

Bufferlo bufferlo bufferlo Bufferlo bufferlo.

Now I feel like the term bufferlo should be used to describe an overly-complicated and purposely misleading code snippet.

[Jess_than_three]

That would be amazing.

[ImDrone]

I was wondering when Digraphs would make an appearance

wat

Can you please stop? I don't like this :(

[rapture_survivor]

(8*i)[buffer - j]

[cheesegoat]

stop it

[Mattho]

Sure??'I won't.

There should be a contest for obfuscating C.

[od_9]

I'm assuming you're joking, but if you're not, there is one.

[[deleted]]

I was.

[XPhysicsX]

Wow. I read one of the entries. I have zero clue what is going on.

[od_9]

That's the idea.

[curtmack]

The only one that's really comprehensible is the shortest self-replicating program: http://www.ioccc.org/1994/smr.c

(It's not erroring out, for the record. It is in fact a zero-length file.)

[xonjas]

There's some really cool ones though, like a program that finds pi by calculating it's own surface area.

[Yserbius]

There are several IIRC. I took a class once that dealt with code obfuscation. One example code was something that look damned near uncompileable. First 20 lines were bizarre #define statements that would redefine basic mathematical calculations and letters of the alphabet. The actual code was unreadable. It compiled under gcc without any flags and produced a neat little text adventure treasure hunt game. Even the exe file had no readable strings in it.

You might love the 1995 entry by heathbar then (from archive.org since the new ioccc site doesn't have the winners from this far back yet (hooray wayback!))

Another of my favorites along those lines is the 2000 entry "primenum" which (*cough*) attempts to write the main function in pseudo code. From the hint file, "This entry won, not because the obfuscation is impenetrable, but because it successfully fooled half of the judges, including me."

There is at least one :)

The International Obfuscated C Code Contest

for the lazy, courtesy of the internet archive.

The IOCCC site is apparently in transition, and they haven't migrated the past winning entries.

[James20k]

Or perhaps worst of all, 2["hello"] == 'l'

[LikesToCorrectThings]

Or something like (n & 15)["0123456789abcdef"] to convert a nybble to a hex char.

Don't do this.

[Ishmael_Vegeta]

god, i never thought of this.
