'arr1' is not an int. It is an array of 1 int.

>>> int arr2[16];
>>> These are ints(plural)

'arr2' is an array of sixteen ints.

Don't be confused by the fact that the name of an array usually decays 
into a pointer to its first element. That's just a conversion, and 
being able to convert one type into another does not make the two types 
the same.
