C++23 likes to move it!
C++14 extended this support so that even converting constructors accepting an rvalue type can be called to invoke an implicit move. As you can see, the two examples follow the same logic, in a sense they are quite symmetric. C++20 introduced some changes in copy elision and overload resolution. As a consequence two() would work even if w was taken as an rvalue (Widget&&). But because of a wording
Adventures In Game Engine Programming
You can find a live demonstration of the library here: https://droplet.fwsnet.net Here is a multi-threaded test… I was thinking a lot about how it would fare against Lua 5.3, which was the scripting language I was using in my game engine. I had experiences where it was really slow, and it made me curious if I could imitate Luas excellent APIs and measure differences in a meaningful way. Eventually
Six Handy Operations for String Processing in C++20/23
In this article, we’ll explore six practical string processing operations introduced in C++20 and C++23. These features represent an evolution in this crucial area, covering a spectrum of operations from searching and appending to creation and stream handling. Let’s start with a simple yet long-awaited feature… 1. contains(), C++23 Finally, after decades of standardization, we have a super easy wa
C++23: Syntactic Sugar with Deducing This – MC++ BLOG
CRTP is typically used to implement static polymorphism. Unlike dynamic polymorphism, static polymorphism happens at compile time and does not require an expensive run-time pointer indirection. C++98 The following program crtp.cpp shows an idiomatic C++98-based implementation of CRTP. // crtp.cpp #include <iostream> template <typename Derived> struct Base{ void interface(){ // (2) static_cast<Deri
C++23: Deducing This – MC++ BLOG
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 to make the implicit this poi
Finite State Machine with std::variant - Vending Machine
In my last article, we discussed Finite State Machines based on std::variant and some cool C++17 techniques. Today I want to go further and show you an example of a Vending Machine implementation. Here’s the previous article Finite State Machine with std::variant - C++ Stories States & Events Here’s a basic diagram that illustrates how the machine is going to work: Following the model from the las
C++23: The Next C++ Standard – MC++ BLOG
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 C++ is more than 40 years old. What happened in the last years? Here is a simpli
