I need to parse it columnwise so that I can randomly know which co-ordinate

Parse it line-by-line (there is no alternative for variable length lines); split each line into fields and build a 2D array from the results.

Now you can access everything in whatever order you like.

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.

  • 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.
