Polymorphic Allocators in C++17September 25, 2023 - 7:43 am
This post starts a miniseries about an almost unknown feature in C++17: polymorphic allocators. I often promised that I would write about polymorphic allocators. Today, I fulfill my promise. Since C++98, you can fine-tune memory allocation in general but also for user-defined types or containers of the standard library. For example, the containers of the […]
C++23: Ranges Improvements and std::generatorSeptember 18, 2023 - 9:28 am
C++20 does not provide concrete coroutines, but C++20 provides a framework for implementing coroutines. This changes with C++23. std::generator is the first concrete coroutine. std::generator is part of the extension of the ranges library in C++23. So, let me start this post with the ranges library in C++20 and its extension in C++23. I will […]
The Final Version of my C++20 BookSeptember 13, 2023 - 7:10 pm
I have given many C++20 classes in the last two years and improved my C++20 knowledge. Consequentially, I updated my C++20 book. This update includes restructured chapters, more detailed information, and additional examples. The book now has almost 700 pages and more than 200 examples. This issue is the final one. I’m done and will […]
C++23: A Multidimensional ViewSeptember 11, 2023 - 6:26 pm
A std::mdspan is a non-owning multidimensional view of a contiguous sequence of objects. The contiguous sequence of objects can be a plain C-array, a pointer with a size, a std::array, a std::vector, or a std::string. Often, this multidimensional view is called a multidimensional array. The number of dimensions and the size of each dimension determine […]
C++23: Four new Associative ContainersSeptember 4, 2023 - 6:51 am
The four associative containers std::flat_map, std::flat_multimap, std::flat_set, and std::flat_multiset in C++23 are a drop-in replacement for the ordered associative containers std::map, std::multimap, std::set, and std::multiset. We have them for two reasons in C++23: memory consumption and performance. With C++23, we have 12 associative Containers. Twelve? Right! Now, I need a systematic and start with the […]
C++23: A New Way of Error Handling with std::expectedAugust 28, 2023 - 6:49 am
C++23 extends the interface of std::optional and gets the new data type std::expected for error handling. Before I dive into the extended monadic interface of std::optional in C++23, I want to introduce this C++17 type. std::optional std::optional is quite comfortable for calculations such as database queries that may have a result. This vocabulary type requires […]
