The only time you NEED the iterator version (as opposed to the range-for above)
is when you want to erase elements.

Also, you can shorten (obfuscate?) that even more:

       std::array<int, 5> arr {1, 2, 3, 4, 5};
       for (auto element : arr)
           std::cout << element << " ";

Though "auto" is more useful for complex data types.
