Chapter 16. File Input/Output
I am the heir of all the ages, in the foremost files of time. �Tennyson
A file is a collection
of
related data. C++ treats a file as a series of bytes. Many files
reside on disk; however, devices such as printers, magnetic tapes,
and communication lines are also considered files.
This chapter discusses three different I/O packages. The first is the
C++ I/O stream classes. This is the most commonly used I/O system and
the one we've been using up to now. Next, we examine
the raw I/O routines that give us direct access to the low-level I/O.
Finally we look at the C I/O system. Although it is somewhat
outdated, C I/O calls still appear in old code. Also, in some cases,
the C-style I/O routines are superior to the ones provided with C++.
