C++ Standard Library

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
