C17 (C Standard Revision)
C17, formally ISO/IEC 9899:2018, is an open standard for the C (programming language), C programming language, prepared in 2017 and published on 2018-07-05. It replaced C11 (C standard revision), C11 (standard ISO/IEC 9899:2011), and is superseded by C23 (C standard revision), C23 (ISO/IEC 9899:2024) since October 2024. Since it was under development in 2017, and officially published in 2018, C17 is sometimes referred to as C18. Changes from C11 C17 fixes numerous minor defects in C11 (C standard revision), C11 without introducing new language features. The __STDC_VERSION__ macro is increased to the value 201710L. For a detailed list of changes from the previous standard, see ''Clarification Request Summary for C11''. Compiler support List of compilers supporting C17: * GNU Compiler Collection, GCC 8.1.0 * LLVM Clang 7.0.0 * IAR_Systems, IAR EWARM v8.40.1 * Microsoft Visual C++ VS 2019 (16.8) * LCC_(compiler)#Pelles_C, Pelles C 9.00 See also * C++23, C++20, C++17, C++ ...

Open Standard
An open standard is a standard that is openly accessible and usable by anyone. It is also a common prerequisite that open standards use an open license that provides for extensibility. Typically, anybody can participate in their development due to their inherently open nature. There is no single definition, and interpretations vary with usage. Examples of open standards include the GSM, 4G, and 5G standards that allow most modern mobile phones to work world-wide. Definitions The terms ''open'' and ''standard'' have a wide range of meanings associated with their usage. There are a number of definitions of open standards which emphasize different aspects of openness, including the openness of the resulting specification, the openness of the drafting process, and the ownership of rights in the standard. The term "standard" is sometimes restricted to technologies approved by formalized committees that are open to participation by all interested parties and operate on a consensus basis ...

International Organization For Standardization
The International Organization for Standardization (ISO ; ; ) is an independent, non-governmental, international standard development organization composed of representatives from the national standards organizations of member countries. Membership requirements are given in Article 3 of the ISO Statutes. ISO was founded on 23 February 1947, and () it has published over 25,000 international standards covering almost all aspects of technology and manufacturing. It has over 800 technical committees (TCs) and subcommittees (SCs) to take care of standards development. The organization develops and publishes international standards in technical and nontechnical fields, including everything from manufactured products and technology to food safety, transport, IT, agriculture, and healthcare. More specialized topics like electrical and electronic engineering are instead handled by the International Electrotechnical Commission.Editors of Encyclopedia Britannica. 3 June 2021.Inte ...

C23 (C Standard Revision)
C23, formally ISO/IEC 9899:2024, is the current open standard for the C programming language, which supersedes C17 (standard ISO/IEC 9899:2018). It was started in 2016 informally as C2x, and was published on October 31, 2024. The freely available draft most similar to the one published is document N3220 (see Available texts, below). The first WG14 meeting for the C2x draft was held in October 2019, virtual remote meetings were held in 2020 due to the COVID-19 pandemic, then various teleconference meetings continued to occur through 2024. In C23, the value of __STDC_VERSION__ changes from 201710L to 202311L. The common names "C17" and "C23" reflect these values, which are frozen prior to final adoption, rather than the years in the ISO standards identifiers (9899:2018 and 9899:2024). Features Changes integrated into the latest working draft of C23 are listed below. Standard Library New functions * Add memset_explicit() function in to erase sensitive data, where memory stor ...

Compatibility Of C And C++
The C and C++ programming languages are closely related but have many significant differences. C++ began as a fork of an early, pre-standardized C, and was designed to be mostly source-and-link compatible with C compilers of the time. Due to this, development tools for the two languages (such as IDEs and compilers) are often integrated into a single product, with the programmer able to specify C or C++ as their source language. However, C is ''not'' a subset of C++, 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-formed C++ code, or to be conforming/well-formed in both languages but to behave differently in C and C++. Bjarne Stroustrup, the creator of C++, has suggested that the incompatibilities between C and C++ should be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

C++03
C++03 is a version of the ISO/ IEC 14882 standard for the C++ programming language. It is defined by two standards organizations, the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC), in standard ISO/IEC 14882:2003. C++03 replaced the prior C++98 standard. C++03 was later replaced by C++11. C++03 was primarily a bug fix release for the implementers to ensure greater consistency and portability. This revision addressed 92 core language defect reports, 125 library defect reports, and included only one new language feature: value initialization. Among the more noteworthy defect reports addressed by C++03 was the library defect report 69, whose resolution added the requirement that elements in a vector are stored contiguously. This codifies the common expectation that a C++ std::vector object uses a memory layout similar to an array. While most implementations satisfied this expectation, it was not required by C++98.

C++11
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, and was later replaced by C++14. The name follows the tradition of naming language versions by the publication year of the specification, though it was formerly named ''C++0x'' because it was expected to be published before 2010. Although one of the design goals was to prefer changes to the libraries over changes to the core language, C++11 does make several additions to the core language. Areas of the core language that were significantly improved include multithreading support, generic programming support, uniform initialization, and performance. Significant changes were also made to the C++ Standard Library, incorporating most of the C++ Technical Report 1 (TR1) libraries, except the library ...

C (programming Language)
C (''pronounced'' '' – like the letter c'') is a general-purpose programming language. It was created in the 1970s by Dennis Ritchie and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted Central processing unit, CPUs. It has found lasting use in operating systems code (especially in Kernel (operating system), kernels), device drivers, and protocol stacks, but its use in application software has been decreasing. C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B (programming language), B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity. It has become one of the most widely used programming langu ...
