#include <iostream>
#include <vector>

int main ()
{
    using namespace std;

    vector <int> v;

    v.push_back (50);
    v.push_back (1);
    v.push_back (987);
    v.push_back (1001);

    // Access objects in a vector using iterators:
    vector<int>::iterator i = v.begin();

    while (i != v.end ())
    {
        size_t nElementIndex = distance (v.begin (),
                      i);

        cout << "Element at position ";
        cout << nElementIndex << " is: " << *i << endl;

        // move to the next element
        ++ i;
    }

    return 0;
