map::crend
Returns a const iterator that addresses the location succeeding the last element in a reversed map.
const_reverse_iterator crend( ) const;
Return Value
A const reverse bidirectional iterator that addresses the location succeeding the last element in a reversed map Class (the location that had preceded the first element in the unreversed map).
Remarks
crend is used with a reversed map just as map::end is used with a map.
With the return value of crend, the map object cannot be modified.
crend can be used to test to whether a reverse iterator has reached the end of its map.
The value returned by crend should not be dereferenced.
Example
// map_crend.cpp
// compile with: /EHsc
#include <map>
#include <iostream>
int main( )
{
using namespace std;
map <int, int> m1;
map <int, int> :: const_reverse_iterator m1_crIter;
typedef pair <int, int> Int_Pair;
m1.insert ( Int_Pair ( 1, 10 ) );
m1.insert ( Int_Pair ( 2, 20 ) );
m1.insert ( Int_Pair ( 3, 30 ) );
m1_crIter = m1.crend( );
m1_crIter--;
cout << "The last element of the reversed map m1 is "
<< m1_crIter -> first << "." << endl;
}
The last element of the reversed map m1 is 1.
