Added in C++20. Provides std::barrier, a reusable thread barrier. <future> Added in C++11. In 32.9.1-1, this section describes components that a C++ program can use to retrieve in one thread the result (value or exception) from a function that has run in the same thread or another thread. <hazard_pointer> Added in C++26. Provides std::hazard ...
Bjarne Stroustrup, the creator of C++, wrote the first version of the stream I/O library in 1984, as a type-safe and extensible alternative to C's I/O library. [5] The library has undergone a number of enhancements since this early version, including the introduction of manipulators to control formatting, and templatization to allow its use with character types other than char.
In the C++ programming language, seekg is a function in the fstream library (part of the standard library) that allows you to seek to an arbitrary position in a file. This function is defined for ifstream class - for ofstream class there's a similar function seekp (this is to avoid conflicts in case of classes that derive both istream and ostream, such as iostream).
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++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, [ 4 ] was approved on 4 September 2020, [ 5 ] [ 6 ] and published in December 2020.
Access to C library functions via namespace ::std and the C++≥98 header names is preferred where possible. To encourage adoption, C++98 obsoletes the C ( *.h ) header names, so it’s possible that use of C compatibility headers will cause an especially strict C++98– 20 preprocessor to raise a diagnostic of some sort.
C++17 is a version of the ISO/IEC 14882 standard for the C++ programming language. ... These were superseded in C++11 by improved facilities such as std:: ...
C++26 is the informal name for the version of the International Organization for Standardization (ISO) and International Electrotechnical Commission (IEC) 14882 standard for the C++ programming language that follows C++23. The current working draft of this version is N4981.
