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 ...
Line length rule can be configured with option --linelength and file extensions can be configured with --extensions (by default: 'h', 'cpp', 'cc', 'cu' and 'cuh'). Some options can be stored in a configuration file CPPLINT.cfg. cpplint is implemented as a Python script. [3] It is distributed under the 3 clause BSD license.
In the C and C++ programming languages, unistd.h is the name of the header file that provides access to the POSIX operating system API. [1] It is defined by the POSIX.1 standard, the base of the Single Unix Specification, and should therefore be available in any POSIX-compliant operating system and compiler.

A client 'creates' a window by requesting that the server create a window. This is done via a call to an Xlib function that returns an identifier for the window, that is, a number. This identifier can then be used by the client for requesting other operations on the same window to the server. The identifiers are unique to the server.
The versioning scheme was changed to that of Ubuntu, with the major and minor number representing the year and month of the release. Version 20.03 is the latest stable release; however for the most up-to-date version the user can download the relatively stable nightly build or download the source code from SVN.
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.
This revision addressed 92 core language defect reports, [2] 125 library defect reports, [3] and included only one new language feature: value initialization. [ 4 ] Among the more noteworthy defect reports addressed by C++03 was the library defect report 69, [ 5 ] whose resolution added the requirement that elements in a vector are stored ...
