<A NAME="sec4"><H3>Description</H3></A>
<P>The class <B><I>basic_iostream</I></B> inherits a number of functions from classes <B><I><A HREF="basic-ostream.html">basic_ostream</A></I></B> and <B><I><A HREF="basic-istream.html">basic_istream</A></I></B>. They assist in formatting and interpreting sequences of characters controlled by a stream buffer. Two groups of functions share common properties, the formatted functions and the unformatted functions. </P>
