Why Array Index starts from Zero?

Question

James Smith · Answer

This boils down to the concept of Binary digits. Take an array size of 64 for 
example. We start from 0 and end at 63. We require 6 bits.But, if we were to 
start from 1 and end at 64, we would require 7 bits to store the same number, 
thus increasing the storage size.
