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.

    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.

    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.

        oops, fixed.

    This is the "How is babby formed??" of programming questions.

    Please tell me who in India taught you how to code, or who otherwise put the idea in your head that array indecies (or anything else programming-wise) should begin with 1, so I can punch them in the neck.

      Nobody taught me, I did self learning from C .. Perl.

      who otherwise put the idea in your head that array indecies (or anything else programming-wise) should begin with 1
      It is purely my idea/thought
      BTW my idea is not to advocate anyone that start using the array index from 1, just wanted to know why it is that way.

      so I can punch them in the neck.
      you can't :)

      'How is babby formed' features the idiotic ramblings of semi-literate native English speakers. targetsmart has not shown himself to be an idiot.

      Why arrays start at index 0 rather than 1 is a good question. It shows that he is questioning the foundations of the language as he learns, and seeking to understand things at a fundamental level.

      Basic, "obvious" questions that are so fundamental as to be invisible to most are the type of questions that bring real understanding and advancement.

      It is sad to see such rudeness on this site. It is even worse to see racist and ad hominem attacks here.

      P.S. The accepted plural form of "index" is typically "indexes", but "indices" is also acceptable. Finding irony of your use of "indecies" is left as an exercise for the reader.
