Introduction

Welcome to Beginning C++. This is a revised and updated version of my previous book, Beginning ANSI C++. The C++ language has been extended and improved considerably since the previous book, so much so that it was no longer possible to squeeze detailed explanations of all of C++ in a single book. This tutorial will teach enough of the essential C++ language and Standard Library features to enable you to write your own C++ applications. With the knowledge from this book you should have no difficulty in extending the depth and scope of your C++ expertise. C++ is much more accessible than many people assume. I have assumed no prior programming knowledge. If you are keen to learn and have an aptitude for thinking logically, getting ...
