  79. The class <code>basic_fstream</code> provides support for both input and output operations on file based streams. It directly inherits <a href="../basic_iostream/start" class="wikilink1" title="io:basic_iostream:start">basic_iostream</a> class and therefore indirectly inherits members of <a href="../ios_base/start" class="wikilink1" title="io:ios_base:start">ios_base</a>, <a href="../basic_ios/start" class="wikilink1" title="io:basic_ios:start">basic_ios</a>, <a href="../basic_istream/start" class="wikilink1" title="io:basic_istream:start">basic_istream</a> and <a href="../basic_ostream/start" class="wikilink1" title="io:basic_ostream:start">basic_ostream</a> classes.
