دانلود کتاب راهنمای C++ Lambda

This book shows the story of lambda expressions in C++. You’ll learn how to use this powerful feature in a step-by-step manner, slowly digesting the new capabilities and enhancements that come with each revision of the C++ Standard. We’ll start with C++98/03, and then we’ll move on to the latest C++ Standards. • C++98/03 – how to code without lambda support. What was the motivation for the new modern C++ feature? • C++11 – early days. You’ll learn about all the elements of a lambda expression and even some tricks. This is the longest chapter as we need to cover a lot. • C++14 – updates. Once lambdas were adopted, we saw some options to improve them. • C++17 – more improvements, especially by handling this pointer and allowing constexpr. • C++20 – in this section we’ll have a look at the latest and very fresh C++20 Standard. Additionally, you’ll find techniques and handy patterns throughout the chapters for using lambda in your code. Walking through the evolution of this powerful C++ feature allows us not only to learn lambdas but also to see how C++ has changed over recent years. In one section you’ll see a technique and then it will be “iterated” and updated in further chapters when new C++ elements are available. When possible, the book cross-links to other related sections of the book.
