Containers library

The Containers library is a generic collection of class templates and algorithms that allow programmers to easily implement standard data structures like queues, lists and stacks.

Three kinds of containers are provided:


In addition, the several container adaptors are provided.

They can be considered containers, but don't meet all the requirements of them.


The idea behind the C++ containers library is that the hard part of using complex data structures has already been completed. If a programmer would like to use a stack of integers, all one has to do is use this code:

std::stack<int> my_stack;

With minimal effort, one can now push and pop integers onto this stack. Because std::stack is a class template, one could specify any data type, not just integers. The std::stack class will provide generic functionality of a stack, regardless of the data in the stack.
