    Project 3 Chapter 17 Files

      Goal

       Show how well you understand C++ file handling.

      Notes

      1. Don't forget to open and close a file! To get full credit you must show that you can do this.
      2. Remember that disks (files) are thousands of times bigger and slower than RAM. Never input a complete file when you can do it one piece at a time.

      Exercises

        17.10+17.9+17.8+17.3 Matching transaction with master file

         Tougher logic than it looks.

        17.12 Tool inventory

         Random access file. Scary.

        17.13 Telephone Number Word Generator

         Note -- I expect you to output every combination of letters -- even if they are not words in your favorite language. Rely on the user to spot a word in their language that means something memorable to them. For example: "DEKNUTH" has a meaning for me, but is not in most dictionaries.

        When you output to a file -- I can run a spell checker on the file and so get the correctly spelled words!
