Answer 3

index no. of arrays are relative to their distance from the first address. so 0th position would be the address itself, 1st position is 0th address + 1 and so on.

Now negative index would be like going to 0th address - 1, which is not allocated to the array. This would result in a segmentation fault error.

Hope this helped
