Example

#include <iostream>
#include <iterator>
#include <string_view>

int main()
{
    std::string_view str_view("abcd");

    auto end = str_view.end();
    auto cend = str_view.cend();

    std::cout << *std::prev(end) << '\n';
    std::cout << *std::prev(cend) << '\n';

    std::cout << std::boolalpha << (end == cend) << '\n';
}

Output:
