They show fstream inheriting from iostream which in turn inherits from istream and ostream.
ifstream and ofstream inherit from istream and ostream individually.

Yes, that's also the way it's shown in Bjarne Stroustrup's book.
But when I look at the header files in VC++ 2008 they do this:

<ostream> includes <ios>
<istream> includes <ostream>
<fstream> includes <istream>
<iostream> includes <istream>

I wonder why they do it that way?

Because it is microsoft?

I should note that what I mentioned before is about the class and not the headers. What headers are included doesn't always indicated what the inheritance of the classes is.

True, but since VC++'s <fstream> doesn't include <iostream> it definitely can't derive from std::basic_iostream
