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;
}
