    The worst code you will ever see hopefully

    Reading any further will probably give you a headache...

    While searching for some code I stumbled across these codes:

    If anyone wants to confirm that this WILL compile and work go ahead...

    Code:
    int max(int a,int b)
    {
        a-=b;
        if(!a)
        goto d;
        if(a<(a-a))
        goto e;
        b+=a;
        goto f;
    d:  if(a!=b)
        goto e;
    f:  a=~b;
        goto d;
    e:  return b;
    }
    This one nearly killed me from looking at it.
    Code:
    int mymax (int(*a)(int(*)(int(*)()),int(*)(int(*)(int**))), int(*b)(int(*)
    (int(*)()),int*,int(*)(int(*)()))){return (int)((((int(*)(int(*)(int(*)()),int(
    *)(int(*)())))a)> ((int(*)(int(*)(int(*)()),int(*)(int(*)())))b))?((int(*)(
    int(*)(int(*)()),int(*)(int(*)())))a):((int(*)(int(*)(int(*)()),int(*)(int(*)(
    ))))b));??>
    The function call:
    Code:
    mymax((int(*)(int(*)(int(*)()),int(*)(int(*)(int**))))3,(int(*)(int(*)(int(*)
    ()),int*,int(*)(int(*)())))52);
    equivalent code
    Code:
    (a<b)?a:b)

    Now remember when getting mad at some newbie programmer it could be much much worse than bad syntax or lack of comments.

    Ah yes, but these examples were DELIBERATELY written to be hard to read.

    If you want more examples, look for the site that hosts submissions to the obfuscated C programming contests. The obfuscated C contests are done as a challenge. And as a tongue-in-cheek swipe at bad programming techniques.

    Code:
    ??>
    Is actually a }. I've never seen it useed before.
    And this
    Code:
    (int(*)(int(*)(int(*)())
    Is useless. It does nothing.

    This wasn't meant to be hard to read . . . at least, I don't think so.

    Not really. What gave me a headache was having to maintain code that was worse than those examples. And people ask my why I'm a clarity nazi.
    My best code is written with the delete key.

    people ask YOUR why you're a clarity nazi?

    Sometimes I forgo correct grammar for clarity. Now shoo.
