Examples of programs that provide a Graphical User Interface.

a) The C++ programs linked from this page are written so that the #include command

#include <iostream.h>

is in use. Because using include commands such as this one is a somewhat old-fashioned way to write C++ programs, many C++ compilers print warning messages when you compile these programs. To get rid of the warnings, the above #include command must be replaced with the program lines

#include <iostream>
using namespace std ;

Nowadays there are new versions of these C++ programs, and in the new versions the above modifications have been made. Although the book still contains the original versions of these programs, it is still a valid book to study the basics of programming with C++.
