std::make_reverse_iterator

Defined in header <iterator>

template <class Iterator>
std::reverse_iterator<Iterator> make_reverse_iterator( Iterator i );

(since C++14)

make_reverse_iterator is a convenience function template that constructs a std::reverse_iterator for the given iterator i with the type deduced from the type of the argument.

Parameters

input iterator to be converted to reverse iterator

Return value

A std::reverse_iterator constructed from i.

Possible implementation

template< class Iterator >
std::reverse_iterator<Iterator> make_reverse_iterator( Iterator i )
{
    return std::reverse_iterator<Iterator>(i);
}

Example

#include <iostream>
#include <iterator>
#include <vector>
#include <algorithm>
  
int main() {
    auto v = std::vector<int>{ 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, ", "));
}

Output:

1, 3, 8, 10, 22, 
22, 10, 8, 3, 1,
