In today’s fast and competitive world, a program’s performance is just as important to customers as the features it provides. This practical guide teaches developers performance-tuning principles that enable optimization in C++. You’ll learn how to make code that already embodies best practices of C++ design run faster and consume fewer resources on any computer—whether it’s a watch, phone, workstation, supercomputer, or globe-spanning network of servers. Author Kurt Guntheroth provides several running examples that demonstrate how to apply these principles incrementally to improve existing code so it meets customer requirements for responsiveness and throughput. The advice in this book will prove itself the first time you hear a colleague exclaim, “Wow, that was fast. Who fixed something?” Locate performance hot spots using the profiler and software timers Learn to perform repeatable experiments to measure performance of code changes Optimize use of dynamically allocated variables Improve performance of hot loops and functions Speed up string handling functions Recognize efficient algorithms and optimization patterns Learn the strengths—and weaknesses—of C++ container classes View searching and sorting through an optimizer’s eye Make efficient use of C++ streaming I/O functions Use C++ thread-based concurrency features effectively

Far too many programmers and software designers consider efficient C++ to be an oxymoron. They regard C++ as inherently slow and inappropriate for performance-critical applications. Consequently, C++ has had little success penetrating domains such as networking, operating system kernels, device drivers, and others. "Efficient C++" explodes that myth. Written by two authors with first-hand experience wringing the last ounce of performance from commercial C++ applications, this book demonstrates the potential of C++ to produce highly efficient programs. The book reveals practical, everyday object-oriented design principles and C++ coding techniques that can yield large performance improvements. It points out common pitfalls in both design and code that generate hidden operating costs. This book focuses on combining C++'s power and flexibility with high performance and scalability, resulting in the best of both worlds. Specific topics include temporary objects, memory management, templates, inheritance, virtual functions, inlining, reference-counting, STL, and much more. With this book, you will have a valuable compendium of the best performance techniques at your fingertips. 0201379503B04062001

Describing how the Assembly language can be used to develop highly effective C++ applications, this guide covers the development of 32-bit applications for Windows. Areas of focus include optimizing high-level logical structures, creating effective mathematical algorithms, and working with strings and arrays. Code optimization is considered for the Intel platform, taking into account features of the latest models of Intel Pentium processors and how using Assembly code in C++ applications can improve application processing. The use of an assembler to optimize C++ applications is examined in two ways, by developing and compiling Assembly modules that can be linked with the main program written in C++ and using the built-in assembler. Microsoft Visual C++ .Net 2003 is explored as a programming tool, and both the MASM 6.14 and IA-32 assembler compilers, which are used to compile source modules, are

The programmer-friendly guide to maximizing C++ application performance! Getting a program to work is just the beginning: it must work efficiently, making the most of limited time, memory, and disk space. Now, legendary programmer Steve Heller --author of the best-seller "Who's Afraid of C++?"-- introduces a collection of power house algorithms that can supercharge virtually any C++ program. From streamlining random access to variable-length records to speeding large database sorts, you'll find it here-along with practical, "nothing-left-out" explanations. Coverage includes: Advanced dynamic hashing and caching algorithms. Bitmaps and other data compression techniques. Fast-sorting algorithms that use memory efficiently. Based on the new ANSI C++ standard, this "programmer-friendly" book includes extensive real-life examples and code samples - all personally typeset by the author to minimize the chance of error. If you want to squeeze every last drop of performance out of your C++ code, Optimizing C++ is the book you've been waiting for! The accompanying CD-ROM includes a complete collection of Steve Heller's Optimizing C++ algorithms, plus an industrial-strength C++ compiler.

Consistent, high-quality coding standards improve software quality, reduce time-to-market, promote teamwork, eliminate time wasted on inconsequential matters, and simplify maintenance. Now, two of the world's most respected C++ experts distill the rich collective experience of the global C++ community into a set of coding standards that every developer and development team can understand and use as a basis for their own coding standards. The authors cover virtually every facet of C++ programming: design and coding style, functions, operators, class design, inheritance, construction/destruction, copying, assignment, namespaces, modules, templates, genericity, exceptions, STL containers and algorithms, and more. Each standard is described concisely, with practical examples. From type definition to error handling, this book presents C++ best practices, including some that have only recently been identified and standardized-techniques you may not know even if you've used C++ for years. Along the way, you'll find answers to questions like What's worth standardizing--and what isn't? What are the best ways to code for scalability? What are the elements of a rational error handling policy? How (and why) do you avoid unnecessary initialization, cyclic, and definitional dependencies? When (and how) should you use static and dynamic polymorphism together? How do you practice "safe" overriding? When should you provide a no-fail swap? Why and how should you prevent exceptions from propagating across module boundaries? Why shouldn't you write namespace declarations or directives in a header file? Why should you use STL vector and string instead of arrays? How do you choose the right STL search or sort algorithm? What rules should you follow to ensure type-safe code? Whether you're working alone or with others, C++ Coding Standards will help you write cleaner code--and write it faster, with fewer hassles and less frustration.

"A guide to optimizing programs on the PC and Unix platforms, this book covers the expediency of optimization and the methods to increase the speed of programs via optimization. Discussed are typical mistakes made by programmers that lessen the performance of the system along with easily implemented solutions. Detailed descriptions of the devices and mechanism of interaction of the computer components, effective ways of programming, and a technique for optimizing programs, are provided. Programmers will also learn how to effectively implement programming methods in a high-level language that is usually done in assembler with particular attention given to the RAM subsystem. The working principles of the RAM and the way in which it is coupled with the processor as well as a description of programming methods that allows programmers to overclock the memory to reach maximum performance are included."
