Proven techniques to improve the efficiency of your programs using the Standard Template Library (STL) Key Features Become familiar with the latest features of C++20 and write better code using the STL Reduce the development time for your applications and enable faster deployment Get up and running with the new and leaner STL capabilities introduced in the latest release Book Description Fast, efficient, and flexible, the C++ programming language has come a long way and is used in every area of the industry to solve many problems. The latest version C++20 will see programmers change the way they code as it brings a whole array of features enabling the quick deployment of applications. This book will get you up and running with using the STL in the best way possible. Beginning with new language features in C++20, this book will help you understand the language's mechanics and library features and offer insights into how they work. Unlike other books, the C++20 STL Cookbook takes an implementation-specific, problem-solution approach that will help you overcome hurdles quickly. You'll learn core STL concepts, such as containers, algorithms, utility classes, lambda expressions, iterators, and more, while working on real-world recipes. This book is a reference guide for using the C++ STL with its latest capabilities and exploring the cutting-edge features in functional programming and lambda expressions. By the end of the book C++20 book, you'll be able to leverage the latest C++ features and save time and effort while solving tasks elegantly using the STL. What you will learn Understand the new language features and the problems they can solve Implement generic features of the STL with practical examples Understand standard support classes for concurrency and synchronization Perform efficient memory management using the STL Implement seamless formatting using std::format Work with strings the STL way instead of handcrafting C-style code Who this book is for This book is for intermediate to advanced C++ programmers who want to get the most out of the Standard Template Library of C++20, the newest version of C++. Basic knowledge of coding and C++ concepts is necessary to get started with this book. Keine Bibliotheksbeschreibungen gefunden. |

However, perhaps half of the book isn't about the latest (i.e., C++20) features at all, but features that any intermediate programmer would already know from earlier versions of the standard.
As to the actual content:
I found there to be far too many errors, typographical and otherwise.
Examples contain a lot of irrelevant code that has nothing to do with the feature being explicated.
On at least one occasion, after creating a tortuous example of ranges; the author presents a pre-C++20 solution that is far simpler. Indeed, at no point does the author provide any kind of argument as to why one would want to use ranges/views in preference to the traditional methods of processing containers.
The only time that efficiency is discussed is in the chapter on concurrency and parallelism. So one reaches the end of the book without any idea as to whether a particular feature is more efficient than older mechanisms for obtaining the same result (this is, of course, a particularly important omission in the case of ranges/views).
On the few occasions that the author does time code, he guesses as to the reason for differences in execution time, instead of examining the assembly code via Compiler Explorer or some such tool.
Oddly, the example use of parameter packs I thought extremely advanced, given the lightweight nature of the rest of the book -- and has very little to help the reader understand the code. I freely admit that I certainly didn't understand it, and I've been using C++ since the days of cfront.
Nico Josuttis's book on C++20 isn't out yet, but when it is -- and that should happen soon -- I expect it to be vastly superior to this one (although likely with some quirky English and its own share of typographical errors, if his other books are any guide). (
