/C++std::span<T,Extent>::rbegin
constexpr reverse_iterator rbegin() const noexcept; | (since C++20) |
Returns a reverse iterator to the first element of the reversed span. It corresponds to the last element of the non-reversed span. If the span is empty, the returned iterator is equal to rend().
Parameters
(none).
Return value
Reverse iterator to the first element.
Complexity
Constant.
Example
#include <algorithm>
#include <iostream>
#include <iterator>
#include <span>
int main()
{
constexpr std::span<const char> code{ "@droNE_T0P_w$s@s#_SECRET_a,p^42!" };
auto hack = [](const unsigned O) { return O-0141<120; };
std::copy_if(code.rbegin(), code.rend(),
std::ostream_iterator<const char>(std::cout), hack);
}Output:
password
