C++ Essentials

Since its introduction less than a decade ago, C++ has experienced growing acceptance as a practical object-oriented programming language suitable for teaching, research, and commercial software development. The language has also rapidly evolved during this period and acquired a number of new features (e.g.,templates and exception handling) which have added to its richness.This app serves as an introduction to the C++ language. It teaches how to program in C++ and how to properly use its features. It does not attempt to teach object-oriented design to any depth, which I believe is best covered in a book in its own right.

In designing this book, I have strived to achieve three goals. First, to produce a concise introductory text, free from unnecessary verbosity, so that beginners can develop a good understanding of the language in a short period of time. Second, I have tried to combine a tutorial style (based on explanation of concepts through examples) with a reference style (based on a flat structure). As a result, each chapter consists of a list of relatively short sections (mostly one or two pages), with no further subdivision. This, I hope, further simplifies the reader’s task. Finally, I have consciously avoided trying to present an absolutely complete description of C++. While no important topic has been omitted, descriptions of some of the minor idiosyncrasies have been avoided for the sake of clarity and to avoid overwhelming beginners with too much information. Experience suggests that any small knowledge gaps left as a result, will be easily filled over time through self-discovery.

This app introduces C++ as an object-oriented programming language. No previous knowledge of C or any other programming language is assumed. Readers who have already been exposed to a high-level programming language (such as Cor Pascal) will be able to skip over some of the earlier material in this book.Although the book is primarily designed for use in undergraduate computer science courses, it will be equally useful to professional programmers and hobbyists who intend to learn the language on their own. The entire book can be easily covered in 10-15 lectures, making it suitable for a one-term or one-semester course. It can also be used as the basis of an intensive 4-5 day industrial training course.

The app is divided into 12 chapters. Each chapter has a flat structure, consisting of an unnumbered sequence of sections, most of which are limited to one or two pages. The aim is to present each new topic in a confined space so that it can be quickly grasped. Each chapter ends with a list of exercises. Answers to all of the exercises are provided in an appendix. Readers are encouraged to attempt as many of the exercises as feasible and to compare their solutions against the ones provided.

For the convenience of readers, the sample programs presented in this book(including the solutions to the exercises) and provided.
