I was suﬃciently impressed with your last eﬀort on the GradeBook class library, but have decided that I want to use more of the functionalities of the C++ language.
Be mindful. Sometimes the data gets corrupted and may result in empty GradeBooks. These cases are well-defined in the method descriptions.
Read the provided header file documentation for instructions on how the functions should work.
I have provided you a set of test apps which you can use to ensure that your code is, at least partially, correct. I would suggest a more rigorous testing scheme to ensure that your methods handle missing data.
Late assignments will lose 25% per day late, with no assignment begin accepted after 3 days (at 100% reduction in points).
You will receive one point for each passed test as illustrated in the test *.cc file. There will be an addi-tional point for compiling against all the tests.
