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. The function library is inherited from C.
-
The Object Oriented Class Library − This is a collection of classes and associated functions.
Standard C++ Library incorporates all the Standard C libraries also, with small additions and changes to support type safety.
The Standard Function Library
The standard function library is divided into the following categories −
- I/O,
- String and character handling,
- Mathematical,
- Time, date, and localization,
- Dynamic allocation,
- Miscellaneous,
- Wide-character functions,
The Object Oriented Class Library
Standard C++ Object Oriented Library defines an extensive set of classes that provide support for a number of common activities, including I/O, strings, and numeric processing. This library includes the following −
- The Standard C++ I/O Classes
- The String Class
- The Numeric Classes
- The STL Container Classes
- The STL Algorithms
- The STL Function Objects
- The STL Iterators
- The STL Allocators
- The Localization library
- Exception Handling Classes
- Miscellaneous Support Library
