Mentions and further readings
Throughout the book, we are referring multiple times to the C++ standard. This document is copy-righted by the International Organization for Standardization. The official C++ standard document can be purchased from here: https://www.iso.org/standard/79358.html. However, multiple drafts of the C++ standard as well as the sources used to generate them are freely available on GitHub at https://github.com/cplusplus/draft. You cand find additional information about the C++ standard at https://isocpp.org/std/the-standard.
A great online resource for C++ developers is the C++ Reference website, available at https://en.cppreference.com/. This provides exhaustive documentation of the C++ language directly derived from the C++ standard. Content from the C++ Reference is quoted several times in the book. The C++ Reference content is licensed under CC-BY-SA license, https://en.cppreference.com/w/Cppreference:Copyright/CC-BY-SA.
At the end of each chapter, you will find a section called Further reading. This section contains a list of readings used as a bibliography and recommended for deepening your knowledge of the presented topics.
