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

See More

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

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,
