C++23: The Small Pearls in the Core Language
The C++23 core language has more to offer than deducing this. Today, I will write about the small pearls. Literal Suffixes C++23 provides new integral literal suffixes for (signed) std::size_t: Literal Suffix Type Example z or Z signed std::size_t auto signed = -2023z; z/Z and u/U std::size_t auto unsigned = 2023uz, std::size_t (C++17) is an […]
C++23: Syntactic Sugar with Deducing This
The Curiously Recurring Template Pattern (CRTP) is a heavily used idiom in C++. It is similarly resistant to understanding as the classic design pattern visitor I presented in my last post: “C++23: Deducing This“. Thanks to deducing this, we can remove the C and R from the abbreviation. CRTP The acronym CRTP stands for the […]
C++23: Deducing This
Anyone who thinks a small C++ standard follows a significant C++ standard is wrong. C++23 provides powerful extensions to C++20. These extensions include the core language, particularly the standard library. Today, I present a small but very impactful feature of the core language: deducing this. Deducing this, sometimes also called explicit object parameter, allows it […]
C++23: The Next C++ Standard
C++23 will be the next C++ standard after C++20. This new standard significantly improves C++ but is less game-changing than C++98, C++11, or C++20. C++23 is more in the tradition of C++17. To understand this next step in the evolution of C++, let me put the C++ standards into the historical context. The C++ Standards […]
Thread-Safe Queue – Two Serious Errors
In my last post “Monitor Object” I implemented a thread-safe queue. I made two serious errors. Sorry. Today, I will fix these issues. First, I want to show you again the erroneous implementation from my last post to understand the context. // monitorObject.cpp #include <condition_variable> #include <functional> #include <queue> #include <iostream> #include <mutex> #include <random> […]
