C++ programmer′s guide to undefined behavior: part 6 of 11
Broken syntax and standard library: ellipsis and functions with arbitrary number of arguments Surely all C++ (and even more so C) programmers are familiar with the printf function family. Among the amazing features of these functions is the capability to take an arbitrary number of arguments. You can also create full-fledged programs using just printf! There are even articles dedicated to research
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
