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
| i | - | 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,
