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.
