SUMMARY
=======

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

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

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

     < deque>

Prototype
---------

     const_iterator begin() const;
     iterator begin();

     const_iterator end() const;
     iterator end();

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 begin member function returns a random-access iterator that points at the
first element of the sequence, or just beyond the end of an empty sequence.

The end member function returns a random-access iterator that points just beyond
the end of the sequence.

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.

     using namespace std;  // std c++ libs implemented in std
     #endif

  typedef deque<int, allocator<int> >  INTDEQUE;

  void main()

  {

      // Create A and fill it with elements 1,2,3,4 and 5
      // using push_back function

      INTDEQUE  A;
      A.push_back(1);
      A.push_back(2);
      A.push_back(3);
      A.push_back(4);
      A.push_back(5);

      // Print the contents of A using iterator
      // and functions begin() and end()

       INTDEQUE::iterator pi;

      for(pi= A.begin();  pi !=A.end(); pi++)
      {
          cout << *pi <<" " ;
      }
          cout<<endl;

  }

Program Output is:

1 2 3 4 5
