insert_iterator::operator++

Increments the insert_iterator to the next location into which a value may be stored.

insert_iterator<Container>& operator++( );
insert_iterator<Container> operator++( int );

Parameters

A insert_iterator addressing the next location into which a value may be stored.

Remarks

Both preincrementation and postincrementation operators return the same result.

Example

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

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

   vector<int> vec;
   for (i = 1 ; i < 5 ; ++i ) 
   {
      vec.push_back (  i );
   }
   
   vector <int>::iterator vIter;
   cout << "The vector vec is:\n ( ";
   for ( vIter = vec.begin ( ) ; vIter != vec.end ( ); vIter++ )
      cout << *vIter << " ";
   cout << ")." << endl;

   insert_iterator<vector<int> > ii ( vec, vec.begin ( ) );
   *ii = 30;
   ii++;
   *ii = 40;
   ii++;
   *ii = 50;

   cout << "After the insertions, the vector vec becomes:\n ( ";
   for ( vIter = vec.begin ( ) ; vIter != vec.end ( ); vIter++ )
      cout << *vIter << " ";
   cout << ")." << endl;
}
The vector vec is:
 ( 1 2 3 4 ).
After the insertions, the vector vec becomes:
 ( 30 40 50 1 2 3 4 ).
