C++20

C++20 represents a significant evolution of the C++ language, introducing key features aimed at improving code clarity, efficiency, and concurrency. Highlights include Concepts, which enforce constraints on template parameters for better error messages; Ranges, a new way to work with sequences of values enhancing standard library algorithms; Coroutines, for writing asynchronous code with improved readability; and enhancements to compile-time evaluation with constexpr and consteval. These additions, along with other library improvements, empower developers to create more expressive, robust, and high-performance applications.
