public member function
std::set::rend
<set>
reverse_iterator rend();
const_reverse_iterator rend() const;
Return reverse iterator to reverse end
Returns a reverse iterator referring to the element right before the first element in the
set container, which is considered its
reverse end.
Notice that
rend does not refer to the same element as
begin, but to the element right before it.
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
set 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 20

// set::rbegin/rend
#include <iostream>
#include <set>
using namespace std;
int main ()
{
int myints[] = {78,21,64,49,17};
set<int> myset (myints,myints+5);
set<int>::reverse_iterator rit;
cout << "myset contains:";
for ( rit=myset.rbegin() ; rit != myset.rend(); rit++ )
cout << " " << *rit;
cout << endl;
return 0;
}

Output:
myset contains: 78 64 49 21 17

Complexity
Constant.
