SUMMARY
=======

The sample code below illustrates how to use the deque::push_back and
deque::pop_back STL functions in Visual C++.

MORE INFORMATION
================

Required Header
---------------

     <deque>

Prototype
---------

     void push_back(const T& x);
     void pop_back();

NOTE: The class/parameter names in the prototype may not match the version in the
header file. Some have been modified to improve readability.

Description
-----------

The push_back function inserts an element with value x at the end of the
container deque. The pop_back function removes the last element of the container
deque, which must be non-empty.

Sample Code
-----------

NOTE: In the first line of the sample code section, /GX is equivalent to /EHsc in
VC++ .NET and is set by default.

             cout << *pdeque <<endl ;
         }

     }

Program output is:

The output is:
