After reading this page about operator<< for ostreams, I noticed that there aren't any overloads for const references. So how then does an ostream handle code like this?:


writer << "some text\n";
writer << 1234;

Notice how 1234 is a const int, so how does that work? Just curious is all [wink]

Simple. The page you linked to is wrong. The insertion operator for an ostream takes an int argument not an int reference.

Of course I did suspect that the page was wrong, except I thought that it would probably use const references instead.

That makes much more sense, thanks
