Well, AFAIK, the output stream flushes itself upon destruction (if there were multiple lines with "cout", then he would have to flush between them), and main() will return 0 invariably (Google always works, right? It doesn't need to return error codes.) Furthermore, this is a joke. Who would actually bother to pay attention to every detail, when this post will eventually sink into obscurity anyway?
