C++ Cookbook (Cookbooks (O'Reilly)) by D. Ryan Stephens

Despite its highly adaptable and flexible nature, C++ is also one of the more complex programming languages to learn. Once mastered, however, it can help you organize and process information with amazing efficiency and quickness.
The C++ Cookbook will make your path to mastery much shorter. This practical, problem-solving guide is ideal if you're an engineer, programmer, or researcher writing an application for one of the legions of platforms on which C++ runs. The algorithms provided in C++ Cookbook will jump-start your development by giving you some basic building blocks that you don't have to develop on your own.

Less a tutorial than a problem-solver, the book addresses many of the most common problems you're likely encounter–whether you've been programming in C++ for years or you're relatively new to the language. Here are just some of the time-consuming tasks this book contains practical solutions for:
— Reading the contents of a directory — Creating a singleton class — Date and time parsing/arithmetic — String and text manipulation — Working with files — Parsing XML — Using the standard containers

Typical of O'Reilly's "Cookbook" series, C++ Cookbook is written in a straightforward format, featuring recipes that contain problem statements and code solutions, and apply not to hypothetical situations, but those that you're likely to encounter. A detailed explanation then follows each recipe in order to show you how and why the solution works. This question-solution-discussion format is a proven teaching method, as any fan of the "Cookbook" series can attest to. This book will move quickly to the top of your list of essential C++ references.
