On the drop-down panel to the page there is a subtitle that says "Unformatted input". That is incorrect as it should be "Unformatted output".

Searching this site for "cout" gives this page as the top result, and no results pointing to or even mentioning the iostream header, where it is defined.
I came to this page when trying to come up with a good method for a new C++ user to figure out what header is needed when using anything in the standard library. I was hoping that they'd be able to come to cppreference.com, search here for the name they're trying to use, then look for the "defined in" text to see what header to use.
