Returns a reverse iterator to the first character of the reversed view. It corresponds to the last character of the non-reversed view.
Parameters
(none)
Return value
const_reverse_iterator to the first character.
Complexity
Constant.
Example
#include <algorithm> #include <iostream> #include <iterator> #include <string_view> int main() { std::ostream_iterator<char> out_it(std::cout); std::string_view str_view("abcdef"); std::copy(str_view.rbegin(), std::next(str_view.rbegin(), 3), out_it); *out_it = '\n'; std::copy(str_view.crbegin(), std::next(str_view.crbegin(), 3), out_it); *out_it = '\n'; }
