C代写:COMP116 File IO




Take any program that you have written this semester

  1. Show file input (get your input from a file)
  2. File output (output to a file)
  3. File append (add to the end of a file)
  4. Also,Try to have your code handle an error if for example you try to read from a file that doesn’t exist.

Most of you might use the bitcoin program or the race betting, but you can do anything you want, or even make up your own original program. For example you could add a save and load to your bitcoin assignment which lets them save the current ledger to a file and load the old ledger in

If you are pressed for time you can choose either 2, or 3 instead of doing both ( just to complete at least the majority of the task if you are rushed) , but you need to understand the difference between them: writing to a file creates a new file to write to and deletes whatever was in it previously if it exists, while appending to a file appends to the end of the existing file.

If you are a beginner you can do the read, write, and append as three separate programs. If you integrate this into one of your existing programs you can just do read and write and skip append if you want.. If you do three simple stand alone programs then please show a read example, a write example, and an append example.

Please make it easy for me to see what you are doing, ie: Document it so it is obvious: Here is my read, here is my write, here is my append.
