An Overview Of C++26: The Library – MathSeptember 9, 2024 - 10:18 am
The most interesting feature of the new C++26 standard library is its improved math support. std::submdspan std::submdspan is s a subspan of an existing span std::mdspan (C++23). The subspan didn’t make it into C++23 and was added with C++26. Before I continue with C++26, I must make a short detour to C++23. hi std::mdspan A […]
An Overview of C++26: The LibrarySeptember 2, 2024 - 10:58 am
In my last post, I overviewed C++26’s core language. Today, I continue with the library. To make it short. The library does not offer such powerful features as the core language. Let me name them and give you a short example directly from the proposal. std::string and std::string_view Processing The functions around std::string and std::string_view […]
An Overview of C++26: Core LanguageAugust 26, 2024 - 8:09 am
C++26 has a lot to offer. Let me directly jump in and give you an overview. This image gives you the first idea of what’s inside or outside C++26. Writing a blog post about the future is always challenging because the design freeze of C++26 is in the first quarter of 2025. Fishing in Murky […]
C++26: The Next C++ StandardAugust 19, 2024 - 9:23 am
C++26 will be the next C++ standard after C++23. This new standard significantly improves C++ and is probably similar game-changing like C++98, C++11, or C++20. Let me put the C++ standards into historical context to help you understand this next step in the evolution of C++. The C++ Standards C++ is more than 40 years […]
C++23: This and ThatAugust 12, 2024 - 8:16 am
I have already written 10 posts about C++23. Today, I want to discuss the features I forgot in the first round. As a short reminder, here are the main C++23 features. Main C++23 Features C++23 offers with deducing this a small but very impactful feature of the core language. Deducing this allows you, similar to […]
Feature Testing MacrosAugust 5, 2024 - 9:02 am
The feature testing macros is a relatively unknown feature in C + + 20. They give you the definitive answer to which C++ feature your compiler supports. When you try out the latest C++ features, you often get errors. Now the question is: who is to blame? Option 3 occurs rarely, so you have only […]
