I gave in my last post "C++20: Coroutines with cppcoro", a basic introduction to the coroutines library from Lewis Baker. This introduction covered the elementary coroutines task and generator. Today, I add threads to tasks and get powerful abstractions. 

The cppcoro library from Lewis Baker gives you what C++20 doesn't give you: a library of C++ coroutine abstractions based on the coroutines TS.

It's a typical requirement for thread management to synchronize them. One thread prepares, in this case, a work-package another thread is waiting for. 

educative.io gave me four vouchers for which they will give a learner 3-month access to all Educative courses.

My story to coroutines in C++20 goes on. Today I dive deep into the coroutines framework to create an infinite data stream. Consequentially, you have to read the two previous posts "C++20: Coroutines - A First Overview", and "C++20: More Details to Coroutines" to be prepared. 

After I gave you in my last post (C++20: Coroutines - A First Overview) the first impression of coroutines, I want to provide today more details. Once more, we get in C++20 not coroutines but a framework for building coroutines. 

I'm looking for proofreaders for my new book "C++ Core Guidelines". The crucial idea of the book is to put the precious ideas of the C++ Core Guidelines into a readable book for the big audience. This book includes more than a hundred examples to study the theory in praxis.

C++20 provides four features that change the way we think about and write modern C++: concepts, the ranges library, coroutines, and modules. I already wrote a few posts to concepts and the ranges library. Let's have a closer look at coroutines.

I want to say a few personal words due to exceptional circumstances.

Today, I finish my experiment writing beloved Python functions in C++. So far, I implemented the Python functions filter, range, and xrange. Today, I have a closer look at the map function and combine the functions map and filter into one function.
