std::make_reverse_iterator - cppreference.com (original) (raw)

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.

[edit] Parameters

[edit] Return value

std::reverse_iterator<Iter>(i)

[edit] Notes

[edit] Example

#include #include #include #include   int main() { std::vector v{1, 3, 10, 8, 22};   std::sort(v.begin(), v.end()); std::copy(v.begin(), v.end(), std::ostream_iterator(std::cout, ", ")); std::cout << '\n';   std::copy(std::make_reverse_iterator(v.end()), std::make_reverse_iterator(v.begin()), std::ostream_iterator(std::cout, ", ")); std::cout << '\n'; }

Output:

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