multiset::rend
Returns an iterator that addresses the location succeeding the last element in a reversed multiset.
const_reverse_iterator rend( ) const;
reverse_iterator rend( );
Return Value
A reverse bidirectional iterator that addresses the location succeeding the last element in a reversed multiset (the location that had preceded the first element in the unreversed multiset).
Remarks
rend is used with a reversed multiset just as end is used with a multiset.
If the return value of rend is assigned to a const_reverse_iterator, then the multiset object cannot be modified. If the return value of rend is assigned to a reverse_iterator, then the multiset object can be modified.
rend can be used to test to whether a reverse iterator has reached the end of its multiset.
The value returned by rend should not be dereferenced.
Example
// multiset_rend.cpp
// compile with: /EHsc
#include <set>
#include <iostream>
int main() {
using namespace std;
multiset <int> ms1;
multiset <int>::iterator ms1_Iter;
multiset <int>::reverse_iterator ms1_rIter;
multiset <int>::const_reverse_iterator ms1_crIter;
ms1.insert( 10 );
ms1.insert( 20 );
ms1.insert( 30 );
ms1_rIter = ms1.rend( ) ;
ms1_rIter--;
cout << "The last element in the reversed multiset is "
<< *ms1_rIter << "." << endl;
// end can be used to terminate an interation
// throught a multiset in a forward order
cout << "The multiset is: ";
for ( ms1_Iter = ms1.begin( ) ; ms1_Iter != ms1.end( ); ms1_Iter++ )
cout << *ms1_Iter << " ";
cout << "." << endl;
// rend can be used to terminate an interation
// throught a multiset in a reverse order
cout << "The reversed multiset is: ";
for ( ms1_rIter = ms1.rbegin( ) ; ms1_rIter != ms1.rend( ); ms1_rIter++ )
cout << *ms1_rIter << " ";
cout << "." << endl;
ms1_rIter = ms1.rend( );
ms1_rIter--;
ms1.erase ( *ms1_rIter );
ms1_rIter = ms1.rend( );
--ms1_rIter;
cout << "After the erasure, the last element in the "
<< "reversed multiset is " << *ms1_rIter << "." << endl;
}
Output
The last element in the reversed multiset is 10.
The multiset is: 10 20 30 .
The reversed multiset is: 30 20 10 .
After the erasure, the last element in the reversed multiset is 20.
