My last post gave you the introduction to modules in C++20. This post shows, how to use existing modules.

Modules is one of the five prominent features of C++20. Modules will overcome the restrictions of header files. They promise a lot. For example, the separation of header and source files becomes as obsolete as the preprocessor. In the end, we will also have faster build times and an easier way to build packages.

Today, I complete the rules of the C++ core guidelines to source files. They are about header files and namespaces.

The organisation of source files is a topic which is quite seldom addressed in C++. With C++20 we will get modules, but until then we should distinguish between the implementation and the interface of our code.

I have prepared the pdf bundle. To get it is quite simple.

Honestly, many programmers in my classes have issues with the syntactic sugar of lambdas. Desugaring lambdas with C++ Insights helps quite often.

Variadic templates are a C++ feature which looks quite magic the first time you see it. Thanks to C++ Insights, most of the magic disappears. 

Today's post from Andreas is about template instantiation. C++ Insights helps you a lot to get a deeper insight into this automatic process.

Andreas Fertigs story with C++ Insights goes on. This weeks post is about type deduction with auto and decltype or as I often phrase it: "Use the smartness of the compiler."

Now, it's time to choose the next pdf bundle? You will get all posts, all source files, and a cmake file to the chosen topic.
