ostream_iterator::ostream_iterator

Constructs an ostream_iterator that is initialized and delimited to write to the output stream.

ostream_iterator(
   ostream_type& _Ostr
);
ostream_iterator(
   ostream_type& _Ostr, 
   const CharType* _Delimiter
);

Parameters

• _Ostr
  The output stream of type ostream_iterator::ostream_type to be iterated over.

• _Delimiter
  The delimiter that is inserted into the output stream between values.

Remarks

The first constructor initializes the output stream pointer with &_Ostr. The delimiter string pointer designates an empty string.

The second constructor initializes the output stream pointer with &_Ostr and the delimiter string pointer with _Delimiter.

Example

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

int main( )
{
   using namespace std;

   // ostream_iterator for stream cout
   ostream_iterator<int> intOut ( cout , "\n" );
   *intOut = 10;
   intOut++;
   *intOut = 20;
   intOut++;

   int i;
   vector<int> vec;
   for ( i = 1 ; i < 7 ; ++i )
   {
      vec.push_back (  i );
   }

   // Write elements to standard output stream
   cout << "Elements output without delimiter: ";
   copy ( vec.begin ( ), vec.end ( ),
          ostream_iterator<int> ( cout ) );
   cout << endl;

   // Write elements with delimiter " : " to output stream
   cout << "Elements output with delimiter: ";
   copy ( vec.begin ( ), vec.end ( ),
          ostream_iterator<int> ( cout, " : " ) );
   cout << endl;
}

Elements output without delimiter: 123456
Elements output with delimiter: 1 : 2 : 3 : 4 : 5 : 6 :
