operator++
public member function
reverse_iterator& operator++();
reverse_iterator operator++(int);
Increment iterator position
Advances the reverse_iterator by one position.
This in fact retrocedes the base iterator kept internally by one position.
Parameters
none (the second version is for the post-increment operator).
Return value
The reverse iterator itself (*this).
