For this assignment, you are to extend the functionality of the Web-based grade servers developed and discussed in class. Both the teacher and student versions should be modified to work with a grade file that contains the complete grade listings for this class. That is, for each student, there should be 4 lines of data, the first containing their name and password, the second containing quiz grades, the third containing homework grades, and the fourth containing test (midterm and final exam) grades. For example,

1. Copy the file student.cpp and modify the program so that it accesses and reports grades from an extended grades file such as the one shown above. For example, the Web page resulting from a query for smith might display: Grades for smith quiz grades: 3 5 4 5 3 4 3 4 homework grades: 80 90 95 80 65 test grades: 80 70
2. Further modify your student grade server so that it computes a student's overall average and reports that number. Recall that quizzes count for 10%, homeworks 40%, the midterm exam 20%, and the final exam 30%. In the case of quizzes only, the lowest grade is dropped. Thus, for the smith example above, the quiz average would be ((3 + 5 + 4 + 5 + 3 + 4 + 3 + 4) - 3) / 7 = 4 = 80%. The resulting Web page might display: Average for smith = 77.8 quiz grades: 3 5 4 5 3 4 3 4 homework grades: 80 90 95 80 65 test grades: 80 70
3. Similarly, copy the file teacher.cpp and modify the program so that it can update the new grades file. Using a Web page interface such as newgrades.html, the teacher should be able to use your program to add grades of any type to a student's record.
