vector::rend
Returns an iterator that addresses the location succeeding the last element in a reversed vector.
const_reverse_iterator rend( ) const;
reverse_iterator rend( );
Return Value
A reverse random-access iterator that addresses the location succeeding the last element in a reversed vector (the location that had preceded the first element in the unreversed vector).
Remarks
rend is used with a reversed vector just as end is used with a vector.
If the return value of rend is assigned to a const_reverse_iterator, then the vector object cannot be modified. If the return value of rend is assigned to a reverse_iterator, then the vector object can be modified.
rend can be used to test to whether a reverse iterator has reached the end of its vector.
The value returned by rend should not be dereferenced.
Example
// vector_rend.cpp
// compile with: /EHsc
#include <vector>
#include <iostream>
int main( )
{
using namespace std;
vector <int> v1;
vector <int>::reverse_iterator v1_rIter;
v1.push_back( 1 );
v1.push_back( 2 );
for ( v1_rIter = v1.rbegin( ) ; v1_rIter != v1.rend( ) ; v1_rIter++ )
cout << *v1_rIter << endl;
}
