insert_iterator::operator=

Assignment operator used to implement the output iterator expression *i = x.

insert_iterator<Container>& operator=(
   typename Container::const_reference _Val
);

Parameters

• _Val
  The value to be assigned to the element.

Return Value

A reference to the element inserted into the container.

Remarks

The member function evaluates Iter = container. insert(Iter, _Val), then returns *this.

Example

// insert_iterator_op_assign.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 ).
