**C++** is named after the compatible with::C language, from which it is derived. C++ extends C into an object-oriented language. However, unlike other object-oriented languages, it doesn't try to force you into object-oriented programming, but is a multi-paradigm language. Besides conventional procedural programming and object-oriented programming, it also supports generic programming.

If you can't find an implementation for your task in the C++ category below, please look in the C category, as many of the tasks can be implemented identically in C and C++.

## VersionsEdit

**C++98**is the version of C++ standardized by ISO in 1998.**C++03**is a minor improvement to C++98, standardized by ISO in 2003.**TR1**(Technical Report 1) is a proposal for extensions to the C++ standard library. It was published in 2007. Many of its proposals made it into C++11. Many compilers support it, but put its headers in a different directory.**C++11**(formerly called**C++0x**and sometimes**C++1x**) is a significant improvement, adding many new language features and libraries. It was standardized by ISO in 2011. Most of its features are available in GCC [1] and Clang [2].**C++14**(formerly called**C++1y**) is a minor improvement to C++11, standardized by ISO in 2014. Most of its features are available in Clang [3], GCC [4], and Visual C++[5].**C++17**(formerly called**C++1z**) is a minor improvement to C++14, standardized by ISO in 2017. Most of its features are available in Clang [6], GCC [7], and Visual C++[8].**C++20**(formerly called**C++2a**) is a major improvement to C++17, standardized by ISO in 2020. Most of its features are implemented by Clang [9], GCC [10], and Visual C++[11]**C++23**(alternatively**C++2b**) is a minor improvement to C++20, expected to be standardized by ISO in 2023. Experimental support exists in GCC[12] and Clang[13]
