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.
