// Concerns:
//: 1 All other manipulators of 'bsl::reverse_iterator' work correctly.
//
// Plan:
//: 1 Create reverse iterators 'it1' and 'it2'. Use 'it1' as a
//: reference and call different manipulators of 'it2'. Verify 'it2'
//: has expected values after each manipulation. (C-1)
//
// Testing:
// bsl::reverse_iterator operator++(int);
// bsl::reverse_iterator& operator+=(typename difference_type n);
// bsl::reverse_iterator& operator--();
// bsl::reverse_iterator operator--(int);
// bsl::reverse_iterator& operator-=(typename difference_type n);
