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
