Если кто не знал, можно вставлять урлы прямо в текст программы:

int main()
{

    switch(count%8){
    case 0: do{    *to = *from++;
    case 7:        *to = *from++;
    case 6:        *to = *from++;
    case 5:        *to = *from++;
    case 4:        *to = *from++;
    case 3:        *to = *from++;
    case 2:        *to = *from++;
    case 1:        *to = *from++;
            }while(--n>0);
    }
}

С наступающим!
