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
