Standard Library - C++
< c++(Redirected from C++ Standard Library)

The C++ Standard Library is standardized collection of macros, values, types, templates, classes, functions, and objects for the C++ programming language declared or defined in 52 C++ library headers. The library provides a set of generic containers, utility functions to manipulate them, generic string and streams for input/output processing, memory management, thread management, and various other common services. The C++ Standard Library also incorporates a subset of the C Standard Library which includes 26 headers under a slightly different name.

The current standard that dictates the C++ Standard Library is C++11 which was published in August of 2011, replacing the the C++03 standard.

All library entities, with the exception of the operator new, operator delete, and macros, are defined within the namespace std or within a namespace netsted within namespace std.

Standard Headers[edit]

The C++ standard library provides 52 C++ library headers:

<algorithm> <array> <atomic> <bitset> <chrono> <codecvt> <complex>
<condition_variable> <deque> <exception> <forward_list> <fstream> <functional> <future>
<initializer_list> <iomanip> <iosfwd> <ios> <iostream> <istream> <iterator>
<limits> <list> <locale> <map> <memory> <mutex> <new>
<numeric> <ostream> <queue> <random> <ratio> <regex> <scoped_allocator>
<set> <sstream> <stack> <stdexcept> <streambuf> <string> <strstream>
<system_error> <thread> <tuple> <typeindex> <typeinfo> <type_traits> <unordered_map>
<unordered_set> <utility> <valarray> <vector>

C Headers[edit]

The C++ standard library provides a subset of the facilities of the C Standard Library in 26 headers. They have the same name as their C header counterparts except the ".h" is dropped and a "c" prefix is added to them.
