I’m looking for proofreaders for my new book “C++20”. The book serves two purposes. It provides you the details of the new C++20 standard and shows you how to use it. This book includes more than one hundred fifty examples to study the theory in praxis.
This post concludes my presentation of library features in C++20. Today I am writing about the class std::source_location and a few functions for bit manipulation.
When your program’s compilation broke with a brand-new C++20 feature, you often end with a few questions: Did I do something wrong? Did I find a compiler bug? Does my compiler not yet support this feature? Thanks to the feature testing in C++20, the last question is easy to answer.
When you compare signed and unsigned integers, you may not get the result you expect. Thanks to the six std::cmp_* functions, there is a cure in C++20.
A new type of the chrono extension in C++20 is a calendar date. C++20 offers various ways to create a calendar date and interact with them.
With C++20, the chrono library from C++11 receives essential additions. The most prominent ones are calendar and time-zones support. But this is by far not all. C++20 gets new clocks, powerful formatting functionality for time durations, and a time-of-day type.
This post concludes my introduction to the chrono extension in C++20. Today I present the time-zones functionality.
Today, I present a few utilities for calculating the midpoint of two values, checking if a std::string starts or ends with a substring, and creating callables with std::bind_front. These little utilities may not seem so minor when you need them.
In my last post, “Calendar and Time Zone in C++20: Calendar Dates”, I presented the new calendar-related data types. Today, I go one step further and interact with them.
Peter Gottschling presented in his last post “std::format in C++20” the basics of the new formatting library in C++20. In today’s post, Peter writes about the formatting of user-defined types.
