Q

What does the following code do and why would anyone write something like that?
void send (int *to, int * from, int count)
{
int n = (count + 7) / 8;
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 );
}
}
