C++23 is the current working version of the C++ standard. No major feature has been included so far, but a series of smaller ones as well as many defect reports have made it already to the standard. Many of these new features are small improvements or things you probably wouldn’t use on a regular basis. However, I want to point here to three C++23 features that, in my opinion, stand out among the others as more likely to be used more often.
In programming, a function is a block of code that performs a computational task. (In practice, people write functions that perform many tasks, which is not very good, but it’s a topic beyond the purpose of this article). Functions are a fundamental concept of programming languages and C++ makes no exception. In fact, in C++ there is a large variety of functions that has evolved over time. In this article, I will give a brief walkthrough of this evolution starting with C++11. Since there are many things to talk about, I will not get into too many details on these topics but will provide various links for you to follow if you want to learn more.
Starting with C++20, some very useful functions for searching have been added to some standard containers, such as std::map, std::set, and std::string. These have been required for a long time and it’s good to see that the committee finally agreed upon their value. I hope this is the beginning of some wonderful additions.
