Break it down into smaller tasks. First you need to read in from a file. Than work on what you get. Than write out to a file. Do you know how to read data in from a file? Once you read in from the file my guess is you would want to "tokenize" the strings so that you can work on them. Do you know how to do that?
Please ignore post, I have no idea what I am talking about.
