This one I made up myself without ripping anyone off.
The following C program is 43 characters long and prints a particular string.
main(){printf("-1--2--3--4--5--6--7--8-");}
Can you write a program in 42 characters or less which does the same thing?
Assume you can use printf without any includes and ignore all warnings.

That is a good answer but it doesn't do exactly the same thing as the original program.

You should be more like the dick judge on American Idol, i.e.:
Your code is sloppy and lacks resonance Down Rodeo, I find myself wondering why I'm reading it at all. Although I was intrigued by it's apparently sassy attitude, it turned out to flat and pretentious. Oh and by the way, IT'S BLATANTLY WRONG AND DOES NOT DO THE EXACT SAME THING YOU PANDY FACKLER. Don't worry though, I'm sure you will find a programming job someday... say 1971..ish.

Yes, helpfully puts() appends a newline. I forgot that :(
main(){int i=1;l:i<9?printf("-%d",i++);goto l;:}
doesn't work I think and is too long anyway.
main(){int i=1;while(i<9)printf("-%d-",i++);}
is shorter, probably works, still too long.
main(){int i=1;for(i;i<9;)printf("-%d-",i++);}
is quite smart I think, ought to work still, the thing with all these is I am hoping since all the bits are on one line the curlies are not needed which is true. Do I get any credit for trying?

Down Rodeo said: main(){int i=1;while(i<9)printf("-%d-",i++);}
is shorter, probably works, still too long. That is 45 characters, but it does the right thing...
Down Rodeo said: main(){int i=1;for(i;i<9;)printf("-%d-",i++);}

Sure! You get virtual kudos.

stanlo said: code main(int a){for(;a-9;printf("-%d-",a++));} ? Looks good. You get a cookie!
(It is dependent on argc being exactly 1, though. Not a huge problem but still avoidable.)
