Return reverse iterator to reverse end
Returns a reverse iterator referring to the element right before the first element in the vector, which is considered its reverse end.
rend refers to the character right before the one that would be referred to by member begin.
Parameters
none
Return Value
A reverse iterator to the reverse end of the sequence.
Both reverse_iterator and const_reverse_iterator are member types. In the vector class template, these are reverse random access iterators, defined as reverse_iterator<iterator> and reverse_iterator<const_iterator> respectivelly.
Example
// vector::rbegin/rend
#include <iostream>
#include <vector>
using namespace std;
int main ()
{
vector<int> myvector;
for (int i=1; i<=5; i++) myvector.push_back(i);
cout << "myvector contains:";
vector<int>::reverse_iterator rit;
for ( rit=myvector.rbegin() ; rit < myvector.rend(); ++rit )
cout << " " << *rit;
cout << endl;
return 0;
}

Notice how the reverse iterator iterates through the vector in a reverse way by increasing the iterator. Output:
Complexity
Constant.
