Well, the code I ran the code through wc and it came out to be 92 chars.
Still, it is a nice piece of code.  However, the following modifications make
the same code only 89 chars.



main(n,m){for(scanf("%d",&m);m>1&m<10;n*=m--);
printf(m-1?"error\n":"answer is %d\n",n);}

Of course, you need to delete the newline after the first line.  The code 
could further be optimized by getting rid of the extra "\n" after error and 
answer which would make it 85.
