"Concurrency with Modern C++" is a journey through the present and upcoming concurrency features in C++. - C++11 and C++14 have the basic building blocks for creating concurrent and parallel programs. - With C++17 we have the parallel algorithms from the Standard Template Library (STL). That means that most STL based algorithms can be executed sequentially, parallel, or vectorized. - The concurrency story in C++ goes on. With C++20 we can hope for extended futures, co-routines, transactions, and more. In addition to explaining the details of concurrency in modern C++, this course gives you many interactive code examples; therefore, you can combine theory with practice to get the most out of it. Apart from theory, this course contains a lot of real-world scenarios and use-cases along with pitfalls and how to overcome them using best practices.
