13. Grading Issues  Note that CodeCrunch is used to provide instant feedback on the correctness of your programs based on a few sets of test data made known to you. (These data sets are on the CS1020 website.)  After the submission deadline, your programs will be tested on more test data that are unknown to you.  The last submitted program for each exercise will be manually graded on style and design besides correctness.  The correctness mark given by CodeCrunch may be overriden by your grader if your program has flaws that are not caught by CodeCrunch’s tests.  Hence, test your programs thoroughly yourself; do not use CodeCrunch as the tester. 13
