back_insert_iterator::reference

A type that provides a reference for the back_insert_iterator.

typedef typename Container::reference reference;

Remarks

The type describes a reference to an element of the sequence controlled by the associated container.

Example

// back_insert_iterator_reference.cpp
// compile with: /EHsc
#include <iterator>
#include <vector>
#include <iostream>

int main( )
{
   using namespace std;
   int i;

   vector<int> vec;
   for (i = 1 ; i < 4 ; ++i )  
   {
      vec.push_back ( i );
   }
   
   vector <int>::iterator vIter;
   cout << "The vector vec is: ( ";
   for ( vIter = vec.begin ( ) ; vIter != vec.end ( ); vIter++)
      cout << *vIter << " ";
   cout << ")." << endl;

   back_insert_iterator<vector<int> >::reference 
        RefLast = *(vec.end ( ) - 1 );
   cout << "The last element in the vector vec is: " 
        << RefLast << "." << endl;
}

The vector vec is: ( 1 2 3 ).
The last element in the vector vec is: 3.
