C++ Library Reference
The standard C++ library is a collection of functions, constants, classes, objects and templates that extends the C++ language providing basic functionality to perform several tasks, like classes to interact with the operating system, data containers, manipulators to operate with them and algorithms commonly needed.
The declarations of the different elements provided by the library are split in several files that shall be included in the code in order to have access to its components:
Provides functionality to use an abstraction called
streams specially designed to perform input and output operations on sequences of character, like files or strings.
This functionality is provided through several related classes, as shown in the following relationship map, with the corresponding header file names on top:
For more info see the reference page for the C++ Input/Output Library.
The elements of the C language library are also included as a subset of the C++ Standard library. These cover many aspects, from general utility functions and macros to input/output functions and dynamic memory management functions.
They are divided in several files. Our reference at this moment covers the following header files of the
C library:
| cassert | C Diagnostics Library (header) |
| cctype | Character handling functions (header) |
| cfloat | Characteristics of floating-point types (header) |
| climits | Sizes of integral types (header) |
| clocale | C localization library (header) |
| cmath | C numerics library (header) |
| csignal | C library to handle signals (header) |
| cstdarg | Variable arguments handling (header) |
| cstddef | C Standard definitions (header) |
| cstdio | C library to perform Input/Output operations (header) |
| cstdlib | C Standard General Utilities Library (header) |
| ctime | C Time Library (header) |
C++ provides a specific class to manipulate strings of characters:
The standard template library defines the following container types:
| vector | Vector (class template) |
| deque | Double ended queue (class template) |
| list | List (class template) |
| stack | LIFO stack (class template) |
| queue | FIFO queue (class template) |
| multiset | Multiple-key set (class template) |
| multimap | Multiple-key map (class template) |
| bitset | Bitset (class template) |
It also provides several algorithms to operate on ranges:
| algorithm | Standard Template Library: Algorithms (library) |
