Which method you use depends on what your data looks like. If you have an array of int, then there may not be a special value that can be the sentinel for the end of the array. On the other hand if you have an array of pointers to something, then maybe a NULL pointer is a good choice as a sentinel. Not always, though. If you had an sparse array of pointers, it would be conventional for the empty elements to be NULL, so you could not use that as the sentinel.

Advantages to passing the length are that you can work your way forwards or backwards through the array without having to count how many first, and you know the bounds, so you shouldn't have any Undefined Behaviour from trying to access outside the array.
