programming challenge (silly)

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

May  I ask: main(n,m){
This looks a bit odd - no declarations for n and m. Doesn't that
make them "ints"? That is fine for n, BUT isn't the second argument
to main a char * something[]?  I would suspect that this example would
crash in Technicolor flames as often as not.

To which I would like to add: 100% legal ANSI C (with no trigraphs :-) ).
