If you know C++, please write code for some of the tasks not implemented in C++.
C++ is named after the 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.
The ++ in C++ is some what of an inside joke, in that C++ is C with a Post Increment operator attached, thus C++ is C + 1; however, this interpretation has the flaw that post-increment increments the value after returning the value, so the post-increment expression still evaluates to the value before the increment.
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++.
Versions[edit]
- C++98 is the version of C++ standardized by ISO in 1998. It is the most commonly used and supported version of the language. The term "C++" usually refers to C++98.
- 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] and GCC [4].
- C++17 (still currently called C++1z) is a minor improvement to C++14 that has reached Draft International Standard [5] in March 2017, meaning publication is due very soon. Most of its features are already available in Clang [6] and GCC [7].
- C++2a (C++20 unofficially) is a major upcoming improvement to C++17 first drafted in July 2017. What proposed features it will have is currently partially implemented by Clang [8] and GCC [9]
