std::ostream_iterator::ostream_iterator

ostream_iterator(ostream_type& stream, const CharT* delim)	(1)
ostream_iterator(ostream_type& stream)	(2)

1) Constructs the iterator with the private ostream_type* member initialized with &stream and the private delimiter pointer initialized with delim.

2) Constructs the iterator with the private ostream_type* member initialized with &stream and the private delimiter pointer initialized with null pointer value.

Parameters

stream	-	the output stream to be accessed by this iterator
delim	-	the null-terminated character string to be inserted into the stream after each output

Example

#include <iostream>
#include <iterator>
#include <algorithm>
int main()
{
    std::ostream_iterator<int> i1(std::cout, ", ");
    std::fill_n(i1, 5, -1);
    std::ostream_iterator<double> i2(std::cout);
    *i2++ = 3.14;
}

Output:

-1, -1, -1, -1, -1, 3.14
