2/*To get the last element of the array we first get the size 
3    of the array by using sizeof().  Unfortunately, this gives 
4    us the size of the array in bytes.  To fix this, we divide
5    the size (in bytes) by the size of the data type in the array.
6    In our case, this would be int, so we divide sizeof(array) 
7    by sizeof(int).  Since arrays  start from 0 and not 1 we 
8    subtract one to get the last element.
