The book in your hands is an introduction to the C++ programming language. It begins with the basics: the reader is not required to have any knowledge of programming. Unlike other books on C++ programming, in this book the question of "why" is considered no less important than the question of "how." And therefore, before outlining the specific features of the C++ language, the reader is explained how they operate in general. After all, each structural feature of the language is a separate touch of a single picture. After reading the book, you can write an intelligible program in C++ and, no less important, you will understand why and how it works. The book is designed for users with different levels of training.
