public member function
std::list::rbegin
<list>
reverse_iterator rbegin();
const_reverse_iterator rbegin() const;
Return reverse iterator to reverse beginning
Returns a reverse iterator referring to the last element in the
list container.
rbegin refers to the element right before the one that would be referred to by member
end.
Parameters
none
Return Value
A reverse iterator to the reverse beginning of the sequence.
Both
reverse_iterator and
const_reverse_iterator are member types. In the
list class template, these are reverse
bidirectional iterators, defined as
reverse_iterator<iterator> and
reverse_iterator<const_iterator> respectively.
Example
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

// list::rbegin/rend
#include <iostream>
#include <list>
using namespace std;
int main ()
{
list<int> mylist;
for (int i=1; i<=5; i++) mylist.push_back(i);
cout << "mylist contains:";
list<int>::reverse_iterator rit;
for ( rit=mylist.rbegin() ; rit != mylist.rend(); ++rit )
cout << " " << *rit;
cout << endl;
return 0;
}

Output:
mylist contains: 5 4 3 2 1

Complexity
Constant.
