<P>There may be times when you want to modify the way a file is opened or used
in a program. For example, in some cases it is desirable that writes append to
the end of a file rather than overwriting the existing values. The file stream
constructor takes a second argument, the <I>open mode</I>, that allows such
variations to be specified. Here is an example that creates a file stream
object <SAMP>Str</SAMP>, connects it to the external file named
<SAMP>"inout.txt"</SAMP>, and opens it for reading and for writing at the end
of the file:</P>
<UL><PRE>
-std::fstream Str("inout.txt",
- std::ios_base::in | std::ios_base::out |
- std::ios_base::app);
+std::fstream Str("inout.txt", std::ios_base::in | std::ios_base::out |
std::ios_base::app);
</PRE></UL>
+<P>
+Note that if the <SAMP>"inout.txt"</SAMP> file doesn't exist it will be
+created.

<P>The open mode argument is of type <SAMP>std::ios_base::openmode</SAMP>,
which is a bitmask type like the format flags and the stream state. <A
