Just a quick question out of curiosity

[Daleth]

Has anyone ever attempted writing a complex program on a single line to see if he or she could do it?

Not really complex but meh, it's single line

int size (char *p)
{
    return (*p ? (1 + size(++p)) : 0);
}

@Smac
That's an error if p is null http://ideone.com/cMnCRj
test the pointer instead http://ideone.com/1UG2qr

Aha, nice nice, thanks for that

E: Another

bool isp_2(int num)
{
    return (((num-1) & 1) & (!((num - 1) & num)));
}
