std::make_reverse_iterator(3)  C++ Standard Libary std::make_reverse_iterator(3)

NAME
     std::make_reverse_iterator - std::make_reverse_iterator

Synopsis
	Defined in header <iterator>
	template<   class  Iter  >					  (since
     C++14)
	std::reverse_iterator<Iter> make_reverse_iterator( Iter i     (constexpr
     since C++17)
	);

	make_reverse_iterator is a convenience function template that constructs
     a
	std::reverse_iterator for the given iterator i (which must be a
	LegacyBidirectionalIterator)  with the type deduced from the type of the
     argument.

Parameters
	i - iterator to be converted to reverse iterator

Return value
	A std::reverse_iterator constructed from i.

Notes
	      Feature-test macro	 Value	  Std		 Feature
	__cpp_lib_make_reverse_iterator 201402L (C++14) std::make_reverse_itera-
     tor

Possible implementation
	template<class Iter>
	constexpr std::reverse_iterator<Iter> make_reverse_iterator(Iter i)
	{
	    return std::reverse_iterator<Iter>(i);
	}

Example
     // Run this code

      #include <algorithm>
      #include <iostream>
      #include <iterator>
      #include <vector>

      int main()
      {
	  std::vector<int> v{1, 3, 10, 8, 22};

	  std::sort(v.begin(), v.end());
	  std::copy(v.begin(), v.end(), std::ostream_iterator<int>(std::cout, ",
     "));
	  std::cout << '\n';

	  std::copy(std::make_reverse_iterator(v.end()),
		    std::make_reverse_iterator(v.begin()),
		    std::ostream_iterator<int>(std::cout, ", "));
	  std::cout << '\n';
      }

Output:
      1, 3, 8, 10, 22,
      22, 10, 8, 3, 1,
