C++ changes some C standard library functions to add additional overloaded functions with const type qualifiers, e.g. strchr returns char* in C, while C++ acts as if there were two overloaded functions const char *strchr(const char *) and a char *strchr(char *). In C23 generic selection is used to make C's behaviour more similar to C++'s. [11]
Visual Studio 2015 is the first version to support Windows 10 and the last version to support Windows 8, Windows Server 2008 R2 SP1 and Windows Server 2012; it's also the last version to support targeting Windows XP SP3, Windows Server 2003 SP2, Windows Vista SP2 and Windows Server 2008 SP2 for C++ applications.
windows.h is a source code header file that Microsoft provides for the development of programs that access the Windows API (WinAPI) via C language syntax. It declares the WinAPI functions, associated data types and common macros. Access to WinAPI can be enabled for a C or C++ program by including it into a source file: #include <windows.h>
Microsoft Visual C++ Cross-Development Edition for the Macintosh was an add-on for Visual C++ that introduced the Windows Portability Library, originally known as Windows Library for Macintosh [16]: 17 or Windows Layer for the Macintosh (WLM), [17]: 16 allowing developers to write applications against the Win32 and MFC APIs that could be ...
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 ...
If the expression e refers to a variable in local or namespace scope, a static member variable or a function parameter, then the result is that variable's or parameter's declared type Otherwise, if e is an lvalue , decltype(e) is T& , where T is the type of e; if e is an xvalue , the result is T&& ; otherwise, e is a prvalue and the result is T .
ICU 70 added e.g. support for emoji properties of strings and can now be built and used with C++20 compilers (and "ICU operator==() and operator!=() functions now return bool instead of UBool, as an adjustment for incompatible changes in C++20"), [11] and as of that version the minimum Windows version is Windows 7.
