C++ Pocket Reference

Introduction

The book "C++ Pocket Reference" by Kyle Loudon was published in 2003 and remains a popular compact guide for programmers working with the C++ language. Despite more than twenty years having passed since its publication, the C++03 standard (on which the book is based) laid a foundation that is still relevant for understanding later versions of the language. With a total of only 144 pages, this reference is ideal for quickly looking up information — it truly fits in a pocket.

What the book is about

"C++ Pocket Reference" is not a textbook, but rather a reference guide. It covers the key elements of the C++ language in a concise, structured form. The book consists of the following sections:

• Data Types and Variables — description of built-in types, modifiers, initialization rules.
• Operators and Expressions — a complete list of operators with precedence and associativity.
• Control Structures — if, switch, for, while, do-while, break, continue, goto.
• Functions — declaration, definition, overloading, inline functions, default arguments.
• Classes and Objects — constructors, destructors, inheritance, virtual functions, abstract classes.
• Templates — function templates, class templates, specialization.
• Standard Library (STL) — containers (vector, list, map, set), iterators, algorithms, strings, input/output streams.
• Preprocessor — #define, #include directives, conditional compilation.
• Keywords and Tables — a complete list of C++ keywords with brief descriptions.

Each section is built on the principle of "minimum theory — maximum code examples." The author provides syntactic constructs with explanations, allowing for quick knowledge refreshment.

Who this book is for

The book is aimed at programmers already familiar with the basics of C++. It will be useful for:

• Students of technical specialties studying C++ at university.
• Developers transitioning from C to C++ who need a compact reference on new features.
• Experienced programmers who want quick access to syntax and the standard library at their fingertips.
• Instructors teaching C++ courses — for preparing materials and quickly checking syntax.

For beginners just starting to learn C++, the book may seem too condensed — it is better to start with a full-fledged textbook (e.g., "C++ Primer" or "The C++ Programming Language" by Bjarne Stroustrup), and use this reference as a supplement.

What the reader will learn

After reading (or using it as a reference), the reader will be able to:

• Quickly find the syntax for any C++ construct.
• Understand the differences between C and C++ in terms of classes, overloading, and templates.
• Effectively use STL containers and algorithms.
• Correctly apply templates and specialization.
• Work with input/output streams (iostream, fstream, stringstream).
• Avoid common errors related to memory management and inheritance.

Strengths of the book

• Compactness — 144 pages that can be carried around. Ideal for quick reference.
• Structuredness — information is divided into logical blocks, with an index.
• Code examples — each section is accompanied by short but illustrative examples.
• Tables — operator precedence, character codes, escape sequences — all in convenient tables.
• Focus on STL — the book dedicates sufficient space to the standard library, which is rare in such thin references.
• Accessibility
