list::crbegin
Returns a const iterator addressing the first element in a reversed list.
const_reverse_iterator rbegin( ) const;
Return Value
A const reverse bidirectional iterator addressing the first element in a reversed list Class (or addressing what had been the last element in the unreversed list).
Remarks
crbegin is used with a reversed list just as list::begin is used with a list.
With the return value of crbegin, the list object cannot be modified. list::rbegin can be used to iterate through a list backwards.
Example
// list_crbegin.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.crbegin( );
cout << "The last element in the list is " << *c1_crIter << "." << endl;
}
The last element in the list is 30.
