In this section, we will use reverse iterators in different ways, just to show how they are used:

1. We need to include some headers first, as always:

      #include <iostream>
      #include <list>
      #include <iterator>

2. Next, we declare that we use namespace std in order to spare us some typing:

      using namespace std;

3. For the sake of having something to iterate over, let's instantiate a list of integers:

      int main()
      {
          list<int> l {1, 2, 3, 4, 5};

4. Now let's print these integers in the reverse form. In order to do that, we iterate over the list by using the rbegin and rend functions of std::list and shove those values out via the standard output using the handy ostream_iterator adapter:

          copy(l.rbegin(), l.rend(), ostream_iterator<int>{cout, ", "});
          cout << 'n';

5. If a container does not provide handy rbegin and rend functions but at least provides bidirectional iterators, the std::make_reverse_iterator function helps out. It accepts normal iterators and converts them to reverse iterators:

          copy(make_reverse_iterator(end(l)),
               make_reverse_iterator(begin(l)),
               ostream_iterator<int>{cout, ", "});
          cout << 'n';
      }

6. Compiling and running our program yields the following output:

      5, 4, 3, 2, 1, 
      5, 4, 3, 2, 1,
