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).
For example, basic_fstream<CharT,Traits> refers to the generic class template that implements input/output operations on file streams. It is usually used as fstream which is an alias for basic_fstream<char,char_traits<char>>, or, in other words, basic_fstream working on characters of type char with the default character operation set.
The C++ <iostream> standard header provides two variables associated with this stream: std::cerr and std::clog, the former being unbuffered and the latter using the same buffering mechanism as all other C++ streams.
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 ...
The C programming language provides many standard library functions for file input and output.These functions make up the bulk of the C standard library header <stdio.h>. [1] The functionality descends from a "portable I/O package" written by Mike Lesk at Bell Labs in the early 1970s, [2] and officially became part of the Unix operating system in Version 7.
Apache C++ Standard Library (The starting point for this library was the 2005 version of the Rogue Wave standard library [15]) Libstdc++ uses code derived from SGI STL for the algorithms and containers defined in C++03. Dinkum STL library by P.J. Plauger; The Microsoft STL which ships with Visual C++ is a licensed derivative of Dinkum's STL.
In 1989, C++ 2.0 was released, followed by the updated second edition of The C++ Programming Language in 1991. [32] New features in 2.0 included multiple inheritance, abstract classes, static member functions, const member functions, and protected members. In 1990, The Annotated C++ Reference Manual was published. This work became the basis for ...
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.
