The C++ programming language is undergoing continuous development and improvement. This effort to keep C++ on the cutting edge of language features is driven by the fact that C++ still finds an important role to play in high-performance, portable applications. Few other languages can be used on as many platforms as C++ without having a runtime environment dependency. This is partly thanks to the nature of C++ as a compiled programming language. C++ programs are built into application binaries through a combination of processes that include compiling and linking.

Compiler choice is particularly important in todays C++ landscape, thanks to the rate at which the language is changing. Development of the C++ programming language was started by Bjarne Stroustrup in 1979, when it was called C with Classes. The language didnt see formal standardization until 1998; an updated standard was published in 2003. There was another gap of eight years until the standard was updated again with the introduction of C++11 in 2011. This version brought a considerable number of updates to the C++ programming language and is distinguished from older C++ with the modern C++ moniker. C++ 17 and C++ 20 deprecated old features and brought many significant changes to the language.

This book introduces you to code written for the C++14 through C++20 ISO standard using both the Clang compiler , Microsoft Visual Studio (VS) 2019, and Xcode. Clang is an open source compiler that started life as a closed source Apple project. Apple released the code to the open source community in 2007, and the compiler has been adding strengths ever since. This book explains how to install and use Clang on a computer running OS X, Windows, or Linux (Ubuntu). The examples that accompany each chapter have been compiled and tested using Clang 3.5 and/or Visual Studio 2019. All of the listed applications are free, so choose which works best for your needs, or use them all to learn more!
