Do not get volume 2 of this book.  It is way too complicated for beginning.

Standard C++ include format

As C++ evolved, different compiler vendors chose different extensions for
file names. In addition, various operating systems have different
restrictions on file names, in particular on name length. These issues
caused source code portability problems. To smooth over these rough edges,
the standard uses a format that allows file names longer than the notorious
eight characters and eliminates the extension. For example, instead of the
old style of including iostream.h, which looks like this:


#include <iostream.h>
you can now write:


#include <iostream>
The translator can implement the include statements in a way that suits the
needs of that particular compiler and operating system, if necessary
truncating the name and adding an extension. Of course, you can also copy
the headers given you by your compiler vendor to ones without extensions if
you want to use this style before a vendor has provided support for it.


The libraries that have been inherited from C are still available with the
traditional ‘.h’ extension. However, you can also use them with the more
modern C++ include style by prepending a “c” before the name. Thus:


#include <stdio.h>
#include <stdlib.h>
become:


#include <cstdio>
#include <cstdlib>
And so on, for all the Standard C headers. This provides a nice distinction
to the reader indicating when you’re using C versus C++ libraries.


The effect of the new include format is not identical to the old: using the
.h gives you the older, non-template version, and omitting the .h gives you
the new templatized version. You’ll usually have problems if you try to
intermix the two forms in a single program.
