#include <iostream>
#include <iterator>

int main() {
    int arr[] = {1, 2, 3, 4, 5};

    // Using 'end' to get the iterator pointing to the end of the array
    auto iterEnd = std::end(arr);

    // Using 'cend' to get a constant iterator pointing to the end of the array
    auto iterCEnd = std::cend(arr);

    return 0;
