How to use the deque::begin and deque:end STL functions in Visual C++ (156591)

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 Visual C++ .NET or in Visual C ++ 2005 and is set by default.

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
