multimap::crbegin
Returns a const iterator addressing the first element in a reversed multimap.
const_reverse_iterator crbegin( ) const;
Return Value
A const reverse bidirectional iterator addressing the first element in a reversed multimap Class or addressing what had been the last element in the unreversed multimap.
Remarks
crbegin is used with a reversed multimap just as begin is used with a multimap.
With the return value of crbegin, the multimap object cannot be modified.
crbegin can be used to iterate through a multimap backwards.
Example
// multimap_crbegin.cpp
// compile with: /EHsc
#include <map>
#include <iostream>
int main( )
{
using namespace std;
multimap <int, int> m1;
multimap <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.crbegin( );
cout << "The first element of the reversed multimap m1 is "
<< m1_crIter -> first << "." << endl;
}
The first element of the reversed multimap m1 is 3.
