C++11 been a long time coming out, and there's been a lot of good summary articles on the Internet about the new features of C++11 so this article is about taking you through some of the new features of C++11

C++ a language that has a large user base and is also used in multiple areas. From the emergence of C++98 to the official finalization of C++11 has gone through more than a decade of accumulation.

It's the second major version of C++11 (the first one is C?98, the latter is C?17, and C?14 is a small improvement on C?11),and is the most important update from C++ C++98 It introduces a number of changes, standardizes established practices, and improves the abstractions available to C++ programmers.

As an important complement and optimization of C++11 C++20 brings the language to the door of modernization, and the expanded features of all these new standards breathe new life into C++ language. C++14/17

 Take you through the modern C-plus and see the common features of C-111

C++11 an extension and fix to the current C++11 C++ and it not only includes new skills in the core language, but also extends the standard library (STL) of C++ incorporating most of C++ Technical Report 1 (TR1) libraries (except for special functions of mathematics).

Key new features of C?11:
