How to get a reverse_iterator

As you can see from the following code, I managed to answer the first half
of the question myself, but can't figure out the second half:

string line("FIRST,MIDDLE,LAST");

// find first element in a comma-separated list
string::iterator comma = find(line.begin(), line.end(), ',');
cout << string(line.begin(), comma) << endl;

cout << string(++comma, line.end()) << endl;
>
// get reverse_iterator from iterator
string::reverse_iterator commar = string::reverse_iterator(comma);
cout << string(line.rbegin(), commar) << endl;
>
// get reverse_iterator from reverse_iterator. wrong. how to fix?
cout << string(++comma, string::reverse_iterator(line.rbegin())) << endl;

* * cout << string(++comma, string::reverse_iterator(line.rbegin())) << endl;

Both arguments for string constructor should be either iterators or
reverse_iterators.
Besides I don't see the point of calling string::reverse_iterator copy
constructor with line.rbegin(). It won't convert the reverse_iterator
-- if that's what you've expected -- it'll just create another
reverse_iterator (only silently casting from const_reverse_iterator).

So, as oppose to double-negative gives you positive, double reverse
iterator doesn't give you a normal iterator, correct?
