  • Have you tried something? Start with some code, it's always good – Rizier123 Mar 15 '15 at 01:06

    Create an array for names; loop through the file one line at a time; extract name from the line; if name isn't in the names array, put it in the array and write the line; continue till end of file – Mark Baker Mar 15 '15 at 01:06
