Yeah, so far I'm the best (after python guys)! who can beat me?

That was though!

I'm on 84 characters now!

80 let's see if you can beat this one!

79 and I don't want any more arguement.

I've cast the spell! :D 76 characters!

Seems I know better spells! Done in only 72

Wow! :D

Here is mine:

main(i, s){
    for(s=8;
        i=getchar(), s+i-18;
        s=i-10?s+i-48:printf("%d\n",s%9+1)+6
    );
}

I don't think anyone will ever be able to get smaller than this, so here is my code (with all it's revisions)!

a;
main(c)
{       
    for(;c=getchar()+a-10;a=c-a?c-38:printf("%d\n",a%9?a%9:9)*0);              /*fixed a bug happened at 021*/
//  for(;c=getchar()+a-48;a=c-a+38?c:printf("%d\n",a%9?a%9:9)*0);              /*72 char*/
//  for(;c=getchar(),c+a-64;a=c<11?printf("%d\n",a%9?a%9:9),0:a+c+6);          /*76 char*/
//  for(;scanf("%c",&c),c+a-64;a=c<11?printf("%d\n",a%9?a%9:9),0:a+c+6);       /*79 char*/
//  for(;scanf("%c",&c),c+a-10;a=c<11?printf("%d\n",a%9?a%9:9),0:a+c-48);      /*80 char*/
//  for(;scanf("%c",&c),c>10?a+=c-48,1:a;c<11?printf("%d\n",a%9?a%9:9),a=0:0); /*85 char*/
}

}

Here is the new revision of your code (70 characters):

for(;c=getchar()+a-10;a=c-a?c-38:printf("%d\n",--a%9+1)*0);
