in thread why the array index has to start at 0??

IMO it makes much sense for the array to have the first index at 1.
we never call first as "0", we always call first as '1'. so this lead to this thinking.

    we never call first as "0", we always call first as '1'. so this lead to this thinking.

    Really?

    • The first km my car drove was km 0000000 on the odometer.
    • The first inch on a ruler is inch zero.
    • The first century AD was century zero.
    • The first raffle ticket on the spool is xxx000.

    It's not exactly a foreign concept.

      The first century AD was century zero.

      I thought the first century A.D. was century 1, the first year of which was year 1 A.D. (with the year before being 1 B.C.), the concept of "zero" not percolating into European thought until some non-zero number of centuries later. Which is why, twenty centuries later, we are stuck with 2001 being the first year of the twenty-first century.

        > the first year of which was year 1 A.D. (with the year before being 1 B.C.)

        Actually the troubles arising from not having a year 0 are a very good argument for arrays starting with 0. :)

    It might make sense to you, but chances are that it won't for the maintainers of your code. Arrays in most languages I know start at index 0, I am not sure going against such a common characteristic is such a good idea.

    Then use COBOL instead.
