Don’t forget the usual documentation requirements. The overall program needs a clearly stated purpose. The program must have a header identifying the assignment, due date, programmer, etc. Functions need stated purpose and pre and post conditions.
You can test your program on the data file in.txt
.
Be careful that you aren’t copying code from anyone or allowing anyone to view your own code. Be careful with hard copy and electronic copy. You would be amazed at the number of plagiarism and complicity charges that arise when one person “loans” copy to another to “get an idea how to do it” only to have the recipient copy and submit the coded directly. Discussion of ideas about solutions is okay – just don’t code together.
