Fun C/C++ Hacks

[nikki]

They might produce less readable code, but hacks are fun. Just today, I was a little bored and was thinking of a way to embed statements (should be expressions, of course) directly into a 'while' condition. I came up with 'while (condition && (expression || true))'. It might not be faster, but it's cooler.

Here's an example:-

Code: Select all

//Absolutely fails for non-numbers.
int stringToInt(char *c)
{
    int ret = *c - '0';
    while (*++c && ((ret = (ret * 10) + (*c - '0')) || true));
    return ret;
}

Tell us about other fun hacks!

Nice one!

I could post some stuff, but all of my code is just one continuous hack

Google for 'obfuscated c'.. and one example is this: (although a little too extreme):-

http://www.ioccc.org/2004/anonymous.c

or this:

http://www.ioccc.org/2004/burley.c

The latter link do a one statement C expression separated by comma.

Of course. I actually downloaded 'em all, and built them and modified a few. Fun stuff there. Did you see the flight simulator?
