Standard Template Library (STL) in C++

Standard Template Library

The C++ STL (Standard Template Library) is a powerful set of C++ template classes to provide general-purpose classes and functions with templates that implement many popular and commonly used algorithms and data structures like vectors, lists, queues, and stacks, etc  .

It has four components :-

• Containers
• Algorithms 
• Functions
• Iterators

Containers

Containers or container classes store objects and data. There are in total seven standard “first-class” container classes and three container adaptor classes and only seven header files that provide access to these containers or container adaptors.

Ex:-

   1. binary_search ( ),

    2. sort( )

    3 find ( )  all these all sample examples and there are 1000 of prebuilt functions are there in STL . 

Algorithms

The header algorithm defines a collection of functions especially designed to be used on ranges of elements.They act on containers and provide means for various operations for the contents of the containers.
