C Std Library

The c standard library also incorporates most headers of the iso c.
C std library. H the c standard library both includes an identically named header and another header of the form cxxx all meaningful cxxx headers are listed above. C 20 provides constrained versions of most algorithms in the namespace std ranges in these algorithms a range can be specified as either an iterator sentinel pair or as a single range argument and projections and pointer to member callables are supported. These functions perform essential services such as input and output and provide efficient implementations of frequently used operations. Every element of the library is defined within the std namespace.
For example the c equivalent for the c language header file stdlib h is cstdlib. The stl provides a set of common classes for c such as containers and associative arrays that can be used with any built in type and with any user defined type. The object oriented class library this is a collection of classes and associated functions. The standard template library stl is a set of c template classes to provide common programming data structures and functions such as lists stacks arrays etc.
Cassert assert h c diagnostics library header cctype ctype h character handling functions. Standard c library incorporates all the standard c libraries. With the exception of complex. A c program can call on a large number of functions from this conforming implementation of the c standard library.
These cover many aspects from general utility functions and macros to input output functions and dynamic memory management functions. H header included in the c standard library places in the global namespace each name that the corresponding. C library the elements of the c language library are also included as a subset of the c standard library. The function library is inherited from c.
Nevertheless for compatibility with c the traditional header names name h like stdlib h are also provided with the same definitions within the global namespace. The c standard library can be categorized into two parts the standard function library this library consists of general purpose stand alone functions that are not part of any class. It is a library of container classes algorithms and iterators. The c standard library is a collection of classes functions macros constants etc which have been written in the core c language.
For more information about visual c run time libraries see crt library features. The standard template library stl is a software library for the c programming language that influenced many parts of the c standard library it provides four components called algorithms containers functions and iterators. Additionally the return types of most algorithms have been changed to return all potentially useful information.
