/C++std::basic_string_view<CharT,Traits>::rbegin, std::basic_string_view<CharT,Traits>::crbegin
constexpr const_reverse_iterator rbegin() const noexcept; | (since C++17) | |
constexpr const_reverse_iterator crbegin() const noexcept; | (since C++17) |
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';
}Output:
