In the last weeks; I learned something new about modules in C++20: private modules fragments and header units. Consequently, I make a short detour in this post and present these new features.

I'm happy to announce the first big update of my C++20 book. The update was mainly due to the improved C++ compiler support of C++20. The update includes concepts, the ranges library, modules, the three-way comparison operator, the format library, and the chrono library.

Now, it's time to choose the next pdf bundle? Get all the material to your chosen topic.

There is a lot of power in the strange-looking three dots that are heavily used in the Standard Template Library. Today, I visualize the expansion of the three dots and show a few use cases.

A variadic template is a template that can have an arbitrary number of template parameters. This feature may seem magical to you if you see it the first time. So, let me demystify variadic templates.

Template instantiation is the creation of a concrete function or a concrete class out of a function template or class template. The creation of template instantiation can be implicit (compiler-generated) or explicit (user-provided).

I'm happy to present the five winners in this post including their answers.

I presented in my last post "Parallel Algorithms of the STL with the GCC Compiler" the necessary theory about the C++17 algorithm. Today, I make a performance test using the Microsoft compiler and the GCC compiler to answer the simple question: Does the execution policy pay off?

GCC supports my favorite C++17 feature: the parallel algorithms of the Standard Template Library (STL). I recognized this a few days ago, and I'm happy to write a post about it and share my enthusiasm.

I give away five vouchers for Stephan Roth's book "Clean C++20", sponsored by the book's publisher Apress.
