insert_iterator::operator*

Dereferences the insert iterator returning the element is addresses.

insert_iterator<Container>& operator*( );

Return Value

The member function returns the value of the element addressed.

Remarks

Used to implement the output iterator expression *Iter = value. If Iter is an iterator that addresses an element in a sequence, then *Iter = value replaces that element with value and does not change the total number of elements in the sequence.

Example

// insert_iterator_op_deref.cpp
// compile with: /EHsc
#include <iterator>
#include <list>
#include <iostream>


int main( )
{
   using namespace std;
   int i;
   list <int>::iterator L_Iter;

   list<int> L;
   for (i = 0 ; i < 4 ; ++i )  
   {
      L.push_back ( 2 * i );
   }

   cout << "The original list L is:\n ( ";
   for ( L_Iter = L.begin( ) ; L_Iter != L.end( ); L_Iter++ )
      cout << *L_Iter << " ";
   cout << ")." << endl;

   insert_iterator< list < int> > Iter(L, L.begin ( ) );
   *Iter = 10;
   *Iter = 20;
   *Iter = 30;

   cout << "After the insertions, the list L is:\n ( ";
   for ( L_Iter = L.begin( ) ; L_Iter != L.end( ); L_Iter++ )
      cout << *L_Iter << " ";
   cout << ")." << endl;
}

The original list L is:
 ( 0 2 4 6 ).
After the insertions, the list L is:
 ( 10 20 30 0 2 4 6 ).
