Displaying the address of an arbitrary pointer in C++ 20 fails but succeeds with C++26. C++20 Only void, const void, and std::nullptr_t pointer types are valid. If you want to display the address of an arbitrary pointer, you must cast it to (const) void*. // formatPointer20.cpp #include <format> #include <iostream> #include <string> int main() { […]
C++26 offers many small improvements around strings and string_views. First of all: What is a string_view? std::string_view A std::string_view is a non-owning reference to a string. It represents a view of a sequence of characters. This sequence of characters can be a C++ string or a C-string. In a typical way, C++17 offers four type […]

This wheelchair should also support standing and sleeping. With this wheelchair, I can move inside and outside my flat and visit friends, things I could […]
My next mentoring program, “Embedded Programming with Modern C++,” starts on January 31st. Registration is open. Here are more details. Embedded Programming with Modern C++ The mentoring program consists of 16 stations. You have to invest at least 3 hours per week for each one. This means the program takes four months, and you can […]
Make the Difference Let’s do something great together: From December 1st to 24th, when you book one of my mentoring programs, I will donate half of the money to ALS research. I will publish an update each week so we can see what we have achieved so far. Here’s more information about me, the structure […]
std::execution offers three types of senders: factories, adapters, and consumers. I’ll take a closer look at these today. Most of the following content is from proposal P2300R10. I will try to represent it more concisely. Sender Factory A sender factory is an algorithm that takes no senders as parameters and returns a sender. I already […]
