Add To My Wish List. Book Sorry, this book is no longer in print. Not for Sale. For this special hardcover edition, two new appendixes on locales and standard library exception safety also available at www. Types and Declarations. Pointers, Arrays, and Structures.

Expressions and Statements. Namespaces and Exceptions. Source Files and Programs. B Compatibility C Technicalities Preface Programming is understanding. Ordinary practical programmers have achieved significant improvements in productivity, maintainability, flexibility, and quality in projects of just about any kind and scale.

New language features such as namespaces, exceptions, templates, and run-time type identification allow many techniques to be applied more directly than was possible before, and the standard library allows the programmer to start from a much higher level than the bare language. About a third of the information in the second edition of this book came from the first.

This third edition is the result of a rewrite of even larger magnitude. However, it is much easier to use a well-designed library than it is to understand the details of its implementation.

Therefore, the standard library can be used to provide realistic and interesting examples well before a reader can be assumed to understand its inner workings. The standard library itself is also a fertile source of programming examples and design techniques.

It is organized around language and library facilities. However, features are presented in the context of their use. That is, the focus is on the language as the tool for design and programming rather than on the language in itself. Except where illustrating technicalities, examples are taken from the domain of systems software. The aim is to take the reader far beyond the point where he or she gets code running primarily by copying examples and emulating programming styles from other languages.

Only a good understanding of the ideas behind the language facilities leads to mastery. Supplemented by implementation documentation, the information provided is sufficient for completing significant real-world projects. The hope is that this book will help the reader gain new insights and become a better programmer and designer.

Without their help and suggestions, this book would have been harder to understand, contained more errors, been slightly less complete, and probably been a little bit shorter. Preface to the Second Edition The road goes ever on and on.

This evolution has been guided by the experience of users of widely varying backgrounds working in a great range of application areas. Some of these experiences are reflected here. In this context, safe means that a class provides a specific type-safe interface between the users of the library and its providers; efficient means that use of the class does not impose significant overheads in run-time or space on the user compared with handwritten C code.

Naturally, the features added and resolutions made since the original edition are integral parts of the presentation. They include refined overloading resolution, memory management facilities, and access control mechanisms, type-safe linkage, ccoonnsstt and ssttaattiicc member functions, abstract classes, multiple inheritance, templates, and exception handling.

Most of the useful classes presented here, such as linked lists, arrays, character strings, matrices, graphics classes, associative arrays, etc. This edition provides a greater emphasis on tutorial aspects than did the first edition of this book. However, the presentation is still aimed squarely at experienced programmers and endeavors not to insult their intelligence or experience. The discussion of design issues has been greatly expanded to reflect the demand for information beyond the description of language features and their immediate use.

Technical detail and precision have also been increased. The reference manual, in particular, represents many years of work in this direction. The intent has been to provide a book with a depth sufficient to make more than one reading rewarding to most programmers.

Preface to the First Edition Language shapes the way we think, and determines what we can think about. A programmer can partition an application into manageable pieces by defining new types that closely match the concepts of the application. This technique for program construction is often called data abstraction. Objects of some user-defined types contain type information. Such objects can be used conveniently and safely in contexts in which their type cannot be determined at compile time.

Programs using objects of such types are often called object based. When used well, these techniques result in shorter, easier to understand, and easier to maintain programs. A class is a user-defined type. Classes provide data hiding, guaranteed initialization of data, implicit type conversion for user-defined types, dynamic typing, user-controlled memory management, and mechanisms for overloading operators.

It also contains improvements that are not directly related to classes, including symbolic constants, inline substitution of functions, default function arguments, overloaded function names, free store management operators, and a reference type. This allows the user-defined types to be implemented with a pleasing degree of efficiency. The current implementation will run on most systems that support C.

This book is primarily intended to help serious programmers learn the language and use it for nontrivial projects. It also provides an overview of this book and explains the approach taken to the description of the language facilities and their use.

Be many people. Give up the game of being always Marcus Cocoza. You have worried too much about Marcus Cocoza, so that you have been really his slave and prisoner. You were always much afraid that Marcus might do a stupid thing, or be bored. What would it really have mattered?

All over the world people are doing stupid things I should like you to be easy, your little heart to be light again. You must from now, be more than one, many people, as many as you can think of Part IV: Chapters 23 through 25 discuss design and software development issues. Appendices: Appendices A through E provide language-technical details. You are encouraged to skim through it, read what appears interesting, and return to it after reading other parts of the book.

Published by Addison Wesley, Inc. The discussion focuses on the language features supporting data abstraction, object-oriented programming, and generic programming. Chapter 3 introduces the basic principles and major facilities of the standard library. This allows me to use standard library facilities in the following chapters. It also allows you to use library facilities in exercises rather than relying directly on lower-level, built-in features.

The introductory chapters provide an example of a general technique that is applied throughout this book: to enable a more direct and realistic discussion of some technique or feature, I occasionally present a concept briefly at first and then discuss it in depth later. This approach allows me to present concrete examples before a more general treatment of a topic.

Thus, the organization of this book reflects the observation that we usually learn best by progressing from the concrete to the abstract — even where the abstract seems simple and obvious in retrospect. Modularity — as supported by namespaces, source files, and exception handling — is also discussed. I assume that you are familiar with the fundamental programming concepts used in Part I. Concrete and abstract classes interfaces are presented here Chapter 10, Chapter 12 , together with operator overloading Chapter 11 , polymorphism, and the use of class hierarchies Chapter 12, Chapter It demonstrates the basic techniques used to provide containers, such as lists, and to support generic programming.

Chapter 14 presents exception handling, discusses techniques for error handling, and presents strategies for fault tolerance. Part IV goes further in this direction. The aim is to provide an understanding of how to use the library, to demonstrate general design and programming techniques, and to show how to extend the library.

Chapter 23 concentrates on design and management issues. Chapter 25 presents some ways of using classes in design. Appendix C presents some language-technical examples. Appendix E discusses the exception-safety guarantees and requirements of the standard library. Section 1. Consequently, I avoid clever or harder-to-understand algorithms. A trivial algorithm is typically better suited to illustrate an aspect of the language definition or a point about program structure.

For example, I use a Shell sort where, in real code, a quicksort would be better. Often, reimplementation with a more suitable algorithm is an exercise. In real code, a call of a library function is typically more appropriate than the code used here for illustration of language features. Textbook examples necessarily give a warped view of software development. By clarifying and simplifying the examples, the complexities that arise from scale disappear. I see no substitute for writing realistically-sized programs for getting an impression of what programming and a programming language are really like.
