gistfile1.txt

            Row r = sr.row(i);
            // r.results_size() tells how many are in map.
            google::protobuf::Map<string, string> m = r.results();
            cout << left << setw(8) << m["id"];
            cout << setw(30) << m["artist"];
            cout << setw(36) << m["title"];
            cout << setw(10) << m["duration"];
