""This may well be the best C++ book I have ever read. I was surprised by the amount I learned." --Matthew Wilson, Development Consultant, Synesis Software "C++ Gotchas is the professional programmer's guide to avoiding and correcting ninety-nine of the most common, destructive, and interesting C++ design and programming errors. It also serves as an inside look at the more subtle C++ features and programming techniques. This book discusses basic errors present in almost all C++ code, as well as complex mistakes in syntax, preprocessing, conversions, initialization, memory and resource management, polymorphism, class design, and hierarchy design. Each error and its repercussions are explained in context, and the resolution of each problem is detailed and demonstrated. Author Stephen Dewhurst supplies readers with idioms and design patterns that can be used to generate customized solutions for common problems. Readers will also learn more about commonly misunderstood features of C++ used in advanced programming and design. A companion Web site, located at http: //www.semantics.org, includes detailed code samples from the book. Readers will discover: How to escape both common and complex traps associated with C++How to produce more reusable, maintainable codeAdvanced C++ programming techniquesNuances of the C++ language "C++ Gotchas shows how to navigate through the greatest dangers in C++ programming, and gives programmers the practical know-how they need to gain expert status.

Discover how to solve real-world system administration problems with this collection of end-to-end shell scripts This comprehensive book takes you step-by-step through the process of writing shell scripts to solve real-world Unix problems and tasks. Each chapter begins by presenting a typical Unix challenge that you’ ll most likely experience at your job. With each challenge, you’ ll learn how to identify a specific goal and start the shell script by defining the correct command syntax to solve the problem. You’ ll find out how to build the shell script around the commands, filter the commands output to strip out the unneeded data, and add options that give users more flexibility on the command line. The approach used will teach you how to attack problems logically. It will also empower you to take the basic command syntax and turn it into a shell scripting solution. Throughout the book, you’ ll find end-to-end shell scripts that you can use to automate repetitive tasks and solve real-world system administration problems. These tasks include: Communications such as automated event notification, monitoring processes locally and on remote systems, and automated FTP file transfersInformation gathering and monitoring for file systems, paging/swap space, system load, applications, processes, and capturing the system’ s configurationPrint queue management to keep the printers printingFloating point mathematics in shell scripts using the bc utility The companion Web site contains all of the shell scripts and most of the functions that are discussed in the book as well as bonus shell scripts for various tasks.
