list::crend

Returns a const iterator that addresses the location succeeding the last element in a reversed list.

const_reverse_iterator rend( ) const;

Return Value

A const reverse bidirectional iterator that addresses the location succeeding the last element in a reversed list Class (the location that had preceded the first element in the unreversed list).

Remarks

crend is used with a reversed list just as list::end is used with a list.

With the return value of crend, the list object cannot be modified.

crend can be used to test to whether a reverse iterator has reached the end of its list.

The value returned by crend should not be dereferenced.

Example

// list_crend.cpp
// compile with: /EHsc
#include <list>
#include <iostream>

int main( ) 
{
   using namespace std;
   list <int> c1;
   list <int>::const_reverse_iterator c1_crIter;

   c1.push_back( 10 );
   c1.push_back( 20 );
   c1.push_back( 30 );

   c1_crIter = c1.crend( );
   c1_crIter --;  // Decrementing a reverse iterator moves it forward in 
                 // the list (to point to the first element here)
   cout << "The first element in the list is: " << *c1_crIter << endl;
}
The first element in the list is: 10
