The C++ Standard Library provides several generic containers, functions to use and manipulate these containers, function objects, generic strings and streams (including interactive and file I/O), support for some language features, and functions for common tasks such as finding the square root of a number.
bit-casting of object representations, with less verbosity than memcpy() and more ability to exploit compiler internals; conditional explicit, allowing the explicit modifier to be contingent on a Boolean expression; constexpr virtual functions; Changes applied to the C++20 working draft in the fall meeting in November 2018 (San Diego) include: [91]
Therefore, a project using #include guards must work out a coherent naming scheme for its include guards, and make sure its scheme doesn't conflict with that of any third-party headers it uses, or with the names of any globally visible macros. For this reason, most C and C++ implementations provide a non-standard #pragma once directive. This ...
An include directive instructs a text file processor to replace the directive text with the content of a specified file. The act of including may be logical in nature. The processor may simply process the include file content at the location of the directive without creating a combined file. Different processors may use different syntax.
This is a list of file signatures, data used to identify or verify the content of a file.Such signatures are also known as magic numbers or Magic Bytes.. Many file formats are not intended to be read as text.
It does not include a standard set of "container types" like the C++ Standard Template Library, let alone the complete graphical user interface (GUI) toolkits, networking tools, and profusion of other functionality that Java and the .NET Framework provide as standard. The main advantage of the small standard library is that providing a working ...

sort is a generic function in the C++ Standard Library for doing comparison sorting.The function originated in the Standard Template Library (STL).. The specific sorting algorithm is not mandated by the language standard and may vary across implementations, but the worst-case asymptotic complexity of the function is specified: a call to sort must perform no more than O(N log N) comparisons ...
