Answer 1

Last element is in position

sizeof(array)/sizeof(array[0]) - 1

Answer 2

There is no defined term as empty array

Your array will always hold some value even if you dont initialize it explicitly

You need to define in your application how will you term it as empty may be by considering if its(element of array) value is 0 or some other value
