Compiler design and implementation: token parsing

[Unregistered]

So how should I start a program....

Is it

void main,

or void main(void)??

This has some parsing information I needed once.

int main(int argc,char *argv[])
{return 0;
}

int main(void)
{return 0;
}

void main(int argc,char *argv[])
{
}

void main(void)
{
}

as you please! depending of what u wanna do:

[Prelude]

It's void main() btw. And in anticipation of the next question, here's how you do it:

main(void){int(c)=6,_c=1,c_=32;o:c>0?printf("%*c%0*c\n",c--,c_,_c,'0'):exit(0),_c+=2;goto o;}

-Prelude

And what, pray tell, does that exactly do, fairest Prelude?

Nice triange man! neat code too. Figure that one out later....! When my brain is awake more

....at least somebody understood. Go on, did you realise before or after you looked at it???

>did you realise before or after
Before since it used my exact wording from the GD board.

>Nice triange man! neat code too. Figure that one out later....!
You should see the code I use to answer that question on IRC. Obfuscation like that can cause your brain to explode.

sh(int it){if (it>1 && printf("%s",it-70?it&1?"*":" ":(it=0,"\n"))) sh(it>>1);}
main(int it){char *b="b~bb~~ ~b~~~FbbvvBb<HbHBBF~~jj~~ H~H~~FbbbbBJ<HbHBBFbbbb~R Hb~~B";
	while(it=*b++) sh(it);
}

I stake no claim to coding this one... only adapting it, and even that burnt a good few brain cells ;-)

[Prelude]

Not bad. Recursion is fun.

x=6,_x=7,x_=7;main_(x,_x)
{return(x>0?x_--,main_(x-
printf("%c",_x),_x):x_);}
main(){x>0?main_(main_(x,
32),42),x_+=_x+=1,printf
("%c",'\n'),--x,main():0;}

HELP!! I CANNOT BELIEVE WHAT I AM SEEING

#include <myheaderfile.h>
#define IF_I_NEED_CONSTANTS    1

int main(int argc, char* argv[]) // GOOD!! no void here please
{
  //CODE HERE
 return 0;  //return with no errors, or set it to return 1; to return with errors
}

NO void main.
void main is ANSI Incorrect
and ANSI is currently in charge of ANSI C

One of the ones I liked best from the Obfucated C contests was a maze genrator who's source code was itself a maze.

Quzah.

Had some code here, decided that it was just a waste of time.

Anyway there was some code for this code on pi
REALLY REALLY UGLY LOOKING!
Obfuscate C all the way!

Do you write any of these yourself? If so, please stop it; my head hurts
