Not to mention that when you use them, you give up most of the
advantages of iostream: no type safety, no extensibility.

A long time ago, g++ had a fairly complex library, with more
functionality than anyone else.  Much of this library is now caduc, and
I think that g++ has put all further development on it on hold.  Just a
suspicion, but it wouldn't surprise me if these two functions fell into
the same category.  (Anyone who actually works on g++ care to confirm or
deny?)

Since this newsgroup concerns the C++ standard, we should
note that neither of these functions is part of standard C++.
You cannot depend on finding them in other implementations.

There are quite a few good C++ textbooks, where "good" depends
on your criteria. A suitable reference for a beginning programmer
is not a good one for an experienced programmer learning C++.
The requirements of someone implementing C++ or validating an
implementation are different still.

If you want the exact language specification, the only source is
the C++ Standard itself. Anything else is commentary. If you
want detailed explanations or a tutorial, the standard is not helpful.
It has a different purpose.

You can find an extensive collection of reviews of C++ books at

Not in MSVC or C++Builder

but in egcs or gcc

there is a method that wors with formatting character.

 ostream& ostream::form(const char *format, ...);
 istream& istream::scan(const char *format, ...);

p.s. Isn't there any good reference manual for C++ ?
     in case of C, Turbo C help or UNIX manpages
     provides exellent reference. it even gives if the
     function is ANSI or POSIX or OS dependent.
     Any good reference rather than the spec itself ?
     Do I have to bye a spec from ANSI to check it out ? Uh :-(
