C++20 is a version of the ISO/IEC 14882 standard for the C++ programming language. C++20 replaced the prior version of the C++ standard, called C++17 , and was later replaced by C++23 . [ 1 ] The standard was technically finalized [ 2 ] by WG21 at the meeting in Prague in February 2020, [ 3 ] had its final draft version announced in March 2020 ...
std::string_view, a read-only non-owning reference to a character sequence or string-slice [31] std::optional, for representing optional objects, a data type that may not always be returned by a given algorithm with support for non-return; std::any, for holding single values of any type
C++ programmers expect the latter on every major implementation of C++; it includes aggregate types (vectors, lists, maps, sets, queues, stacks, arrays, tuples), algorithms (find, for_each, binary_search, random_shuffle, etc.), input/output facilities (iostream, for reading from and writing to the console and files), filesystem library ...
C++11 is a version of a joint technical standard, ISO/IEC 14882, by the International Organization for Standardization (ISO) and International Electrotechnical Commission (IEC), for the C++ programming language. C++11 replaced the prior version of the C++ standard, named C++03, [1] and was later replaced by C++14.
The last-used version of Linux libc used the internal name libc.so.5. Following on from this, glibc 2.x on Linux uses the soname libc.so.6 [ 23 ] [ better source needed ] In 2009, Debian and a number of derivatives switched from glibc to the variant [ 25 ] eglibc. [ 26 ]
A tracking reference in C++/CLI is a handle of a passed-by-reference variable. It is similar in concept to using *& (reference to a pointer) in standard C++, and (in function declarations) corresponds to the ref keyword applied to types in C#, or ByRef in Visual Basic .NET. C++/CLI uses a ^% syntax to indicate a tracking reference to a handle.
Clang/LLVM can compile a working modified Linux kernel. [41] January 2011: Preliminary work completed to support the draft C++0x standard, with a few of the draft's new features supported in Clang development version. [42] [14] 10 February 2011: Clang can compile a working HotSpot Java virtual machine. [27] 19 January 2012
The C++ Standard Library provides several generic containers, functions to use and manipulate these containers, function objects, generic strings and streams (including interactive and file I/O), support for some language features, and functions for common tasks such as finding the square root of a number.
