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 ).
