deque::begin and deque::end

Illustrates how to use the deque::begin and deque::end Standard Template Library (STL) functions in Visual C++.

const_iterator begin( ) const;
   iterator begin( );
const_iterator end( ) const;
   iterator end( );

Remarks

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.

Example

// begin.cpp
// compile with: /EHsc
//
// Functions:
//
//    begin()
//    end()

#include <iostream>
#include <deque>

using namespace std;

typedef deque<int >  INTDEQUE;

int 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;
}

Output

1 2 3 4 5
