This compiler is fast, free, and has the best compliance to the new (1998) ANSI C++ of any compiler out there. Presumably you want to learn and use C++.
Why would you want to use this C++ compiler? I assume you are capable of downloading and installing a file by yourself, and are using some variant of Microsoft Windows. The aim of this tutorial is to get beginners up and programming in C++, easily and cheaply, using a nice friendly replacement for Borland's own expensive GUIs. These are the core of the retail Borland programming tools, like Borland C++ Builder - all the power that runs these expensive products, but without the fancy, user friendly graphical interface - you have to pay for that. They are giving away are the command-line compiler tools and libraries. In mid-February 2000 the people responsible for Borland's C++ products made the core of their product line available as a free download.
