Introduction

C++17 is a significant update for the language, and it brings a lot of features in the Standard Library.

So far, this book has covered the most important aspects, but there are many more things to describe!

This part of the course briefly summarises other changes in the Standard Library:

• What’s std::byte?
• What are the new functionalities of maps and sets
• New algorithms: sampling
• Special Mathematical Functions
• Shared Pointers and Arrays
• Non-member size(), data() and empty()
• constexpr additions to the Standard Library
• How to lock multiple mutexes with scoped_lock?
• What’s a polymorphic allocator? How can it help with memory management?

Let’s get started with std::byte.
