Please also tell your students that including <iostream> is not enough to use std::cout, it is only guaranteed to be declared. If you want to output something, you also need <ostream>. Most standardlibraries indirectly include <ostream> into <iostream> though, so it works most of the time. > If I remove that line, then the swap function becomes > unrecognized. So for some reason, iostream is prototyping swap either > directly or indirectly. Right, but just as with above iostream/ostream, this is not something you should rely on. Only by including <algorithm> you are guaranteed to get std::swap().
