By watching this video I was surprised to learn that in the first example, the range-based for-loop includes the '\0' character in the loop. I would have expected the loop to only run 5 times instead of 6. Lesson learned, thanks a lot for the informational video!

This is an excellent way to understand the range-based for loop.
