Answer is Zero

The array is initialized with 5 elements.We will loop through this array using for loop from 0 to length of the array i.e 5. The output of the program is based on array of i minus array.length minus i.  On first iteration,  array of i equals 5 and array.length minus i equals 5 minus 0 equals 5. Then,  5 minus 5 becomes zero. On second iteration,  array of i equals 4 and array.length minus i equals 5 minus 1 equals 4. Then,  4 minus 4 becomes zero.

Similarly, for all iterations it will generate zero as the output. For more info visit
