Introductory programming books for C++ exist aplenty. But many—probably the great majority—are “introductory” only in the sense that they don’t assume knowledge of C++ specifically. They usually assume that you’ve programmed in another language before, preferably in several.
This book does not make that assumption. All that’s required is that you’re comfortable with a computer and that you’ve run applications such as a word processor or e-mail reader. Once you narrow the available C++ texts down to those that require no programming experience at all, there’s a much smaller group of books from which to choose.
