However, C is not a subset of C++, [3] and nontrivial C programs will not compile as C++ code without modification. Likewise, C++ introduces many features that are not available in C and in practice almost all code written in C++ is not conforming C code. This article, however, focuses on differences that cause conforming C code to be ill ...

Although modules were first introduced in C++20, standard library modules were only standardised as part of the language in C++23. These named modules were added to include all items declared in both global and std namespaces provided by the importable standard headers. Macros are not allowed to be exportable, so users have to manually include ...
Visual C++ 2015 (also known as Visual C++ 14.0) was released on July 20, 2015. [45] It features improved C++11/14/17 support. [ 46 ] Without any announcement from Microsoft, Visual Studio 2015 Update 2 started generating telemetry calls in compiled binaries.
C++23, formally ISO/IEC 14882:2024, [1] is the current open standard for the C++ programming language that follows C++20.The final draft of this version is N4950. [2] [3]In February 2020, at the final meeting for C++20 in Prague, an overall plan for C++23 was adopted: [4] [5] planned features for C++23 were library support for coroutines, a modular standard library, executors, and networking.
Since C++20, C++ has offered modules as a modern alternative to precompiled headers, [10] however they differ from precompiled headers in that they do not require the preprocessor directive #include, but rather are accessed using the word import. A module must be declared using the word module to indicate that a file is a module.
CppDepend is a static analysis tool for C/C++ code. This tool supports a large number of code metrics, allows for visualization of dependencies using directed graphs and dependency matrix . The tools also performs code base snapshots comparison, and validation of architectural and quality rules.
