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.
The C standard library is declared as a collection of header files. The C++ standard library is similar, but the declarations may be provided by the compiler without reading an actual file. C standard header files are named with a .h file name extension, as in #include <stdio.h>. Typically, custom C header files have the same extension.
C standard library functions are exported from the C++ standard library in two ways. For backwards-/cross-compatibility to C and pre-Standard C++, functions can be accessed in the global namespace ( :: ), after #include ing the C standard header name as in C. [ 40 ] Thus, the C++98 program
For #include guards to work properly, each guard must test and conditionally set a different preprocessor macro. 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.
C++20 is a version of the ISO/IEC 14882 standard for the C++ ... various constexpr library bits ... including new import and module. New attributes in C++20: ...
The C++ standard library is a collection of utilities that are shipped with C++ for use by any C++ programmer. It includes input and output, multi-threading, time, regular expressions, algorithms for common tasks, and less common ones (find, for_each, swap, etc.) and lists, maps and hash maps (and the equivalent for sets) and a class called vector that is a resizable array.
Open Asset Import Library (Assimp) is a cross-platform 3D model import library which aims to provide a common application programming interface (API) for different 3D asset file formats. Written in C++ , it offers interfaces for both C and C++.
