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

Run this code

    #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
