C++20
C++20 is a major revision of the C++ programming language standard, officially released in December 2020. It introduces significant new features and improvements, including modules, concepts, coroutines, ranges, and new standard library components, aimed at enhancing code safety, performance, and developer productivity. This version continues the evolution of C++ towards more expressive, efficient, and maintainable code.
Developers should learn C++20 when working on high-performance applications, systems programming, game development, or embedded systems where modern C++ features can reduce boilerplate and improve correctness. It's particularly useful for projects requiring compile-time safety with concepts, modular codebases with modules, or asynchronous programming with coroutines, making it essential for staying current in C++ development.
