G'day rahul02,

This is an inappropriate way to ask a question here. You should know this from your last (and only other) post, "Perl Script for reading a mathematical expression", which contained just:

"i want to know the basic idea for writing a perl script which will read a mathematical expression from user, evaluate the result and print on the screen."

I suggest you read both "How do I post a question effectively?" and "How (Not) To Ask A Question".

"perlintro -- a brief introduction and overview of Perl" should provide the basics you need; follow the links provided for more detailed information on the topics of interest (e.g. Files and I/O).

Use Text::CSV (or one of its related modules) for your CSV work.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
    & &amp;
    < &lt;
    > &gt;
    [ &#91;
    ] &#93;
  • Link using PerlMonks shortcuts! What shortcuts can I use for linking?
