I need help with C++.

CSCE 240 HOMEWORK 4 You shall submit a zipped, and only zipped, archive of your homework directory, hw4. The directory shall contain, at a minimum, the files src/grade.cpp, inc/grade.h, src/gradebook. cpp and inc/gradebook.h. Name the archive submission file hw4.zip I will use my own makefile to compile and link to your src/grade.cpp, inc/grade.h, src/gradebook.cpp and inc/gradebook.h files. You must submit, at least, these four files. The GradeBook object will provide a means to manage grades. The Grade object represents the scored outcome of a student submissions. 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 methods should work. You will receive points as follows: 1. test-grade-constructor: 0.7 points 2. test-grade-toDouble: 0.7 points 3. test-grade-tostring: 0.7 points 4. test-grade-toLetter: 0.7 points 5. test-grade-equals: 0.7 points 6. test-grade-dividedBy: 0.7 points 7. test-grade-plus: 0.7 points 8. test-gradebook-add-and-get: 0.7 points 9. test-gradebook-add: 0.7 points 10. test-gradebook-calcAverage: 0.7 points Total: 7.0 Points Possible - compilation of each test (ten tests above): 0.1 points - grade.cc style: 0.5 points - grade.h style: 0.5 points - gradebook. cc style: 0.5 points - gradebook. h style: 0.5 points Total: 3.0 Points Possible I have provided you basic 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.
