C++ Standards refer to the official specifications that define the C++ programming language. These standards ensure consistency and compatibility across different compilers and platforms. The most notable versions include C++98, C++03, C++11, C++14, C++17, and C++20, each introducing new features and improvements to enhance programming efficiency and performance. The development of C++ Standards is overseen by the International Organization for Standardization (ISO) through a committee known as WG21. This committee gathers input from the C++ community, including developers and researchers, to evolve the language and address modern programming needs.
