They are not part of standard C++. You are looking for std::cout,
    and std::string, std::endl.

Now I wish gcc 3.x would say something akin to: 'cout' not
    defined. (Perhaps you need a using directive such as 'using std::cout'
    or explicit qualification?). Of course that kind of warning would
    require each unrecognized name to be looked up a second time ...
