Re^2: why the array index has to start at 0??

[Anonymous Monk]

'0' does not come in natural no. It comes in whole no. Natural no. starts with '1'

Wikipedia: By most definitions 0 is a natural number,...

From Wikipedia Natural_number as well:

There is no universal agreement about whether to include zero in the set of natural numbers: some define the natural numbers to be the positive integers {1, 2, 3, ...}, while for others the term designates the non-negative integers {0, 1, 2, 3, ...}. The former definition is the traditional one, with the latter definition having first appeared in the 19th century.

To me it seems math people usually exclude zero while computer people include zero.
