std::ostrea...eam_iterator(3) C++ Standard Libarystd::ostrea...eam_iterator(3)

NAME
       std::ostream_iterator::ostream_iterator	 -  std::ostream_iterator::os-
       tream_iterator

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

	  1) Constructs	the iterator with stream as the	associated stream  and
       delim as	the
	  delimiter.
	  2)  Constructs the iterator with stream as the associated stream and
       a null pointer
	  as the delimiter.

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
       // Run this code

	#include <iostream>
	#include <iterator>
	#include <algorithm>
	#include <numeric>
	int main()
	{
	    std::ostream_iterator<char>	oo {std::cout};
	    std::ostream_iterator<int> i1 {std::cout, ", "};
	    std::fill_n(i1, 5, -1);
	    *oo++ = '\n';

	    std::ostream_iterator<double> i2 {std::cout, "; "};
	    *i2++ = 3.14;
	    *i2++ = 2.71;
	    *oo++ = '\n';

	    std::common_iterator<std::counted_iterator<std::ostream_itera-
       tor<float>>,
				 std::default_sentinel_t>
		first	     {	     std::counted_iterator{std::ostream_itera-
       tor<float>{std::cout," ~	"}, 5} },
		last { std::default_sentinel };
	    std::iota(first, last, 2.2);
	    *oo++ = '\n';
	}

Output:
	-1, -1,	-1, -1,	-1,
	3.14; 2.71;
	2.2 ~ 3.2 ~ 4.2	~ 5.2 ~	6.2 ~
