Modernes C++

This page is the starting point for my blog Modernes C++. A simple overview of my existing and upcoming posts.

This overview serves two purposes. At first, the structure gives you in one view an overview, which posts are already written and how you can find them. At second, I give you an outline of all posts, which will be written. I will successively refine the outline to make the future of this post transparent. This purpose is a more challenging task for me.

The C++ Standard Library		Concurrency With Modern C++		Get Both as one Bundle
With C++11, C++14, and C++17 we got a lot of new C++ libraries. In addition, the existing ones are greatly improved. The key idea of my book is to give you the necessary information to the current C++ libraries in about 200 pages.		C++11 is the first C++ standard that deals with concurrency. The story goes on with C++17 and will continue with C++20. I'll give you a detailed insight in the current and the upcoming concurrency in C++. This insight includes the theory and a lot of practice with more the 100 source files.		Get my books "The C++ Standard Library" (including C++17) and "Concurrency with Modern C++" in a bundle. In sum, you get more than 600 pages full of modern C++ and more than 100 source files presenting concurrency in practice.
