The Formatting Library in C++20: The Format String (2)
In my last post, “The Formatting Library in C++20: The Format String“, I presented a few of the format specifications of the format string. Today, I finish my job. In today’s post, I will write about the width, precision, and type of the format specification. If you want to know more about the argument id, […]

As always, I’m pretty busy. I have given C++ classes, created a new mentoring program, and finished my ALS fundraising campaign. But this is not all. Classes and Mentoring Last week, I finished my previous C++20 class. What should I say? It was much fun. Additionally, I finished my fourth mentoring program, “Concurrency with Modern […]

Although Peter Gottschling wrote two great blog posts about the formatting library in C++20 (“std::format in C++20“, “C++20: Extend std::format for User-Defined Types“, I will write about the formatting library again. The reason is simple: […]
My ALS Journey: 4/n
In the last three weeks, a lot happened. I was in the ALS-Ambulanz in Ulm and started a money-raising campaign. Business as Usual After the Christmas break, business as usual is back. I am giving a 3-day Python class this week, teaching the basics and object orientation with Python. I have a long Python history […]
std::span in C++20: More Details
A std::span represents an object that refers to a contiguous sequence of objects. Today, I want to write about its not-so-obvious features. A std::span, sometimes also called a view, is never an owner. This contiguous memory can be a plain array, a pointer with a size, a std::array, a std::vector, or a std::string. A typical […]
