Please submit the C++ code for the combined questions below. You CANNOT use namespace STD so please refrain from using.

This assignment involves 4 files: student.h, grade.h, student.cpp, grade.cpp. It also has main.cpp to run it all.

Your Help Is Greatly Appreciated, I am having trouble using C++ Classes.

Exercise P5.9. Implement a class Student. For the purpose of this exercise, a student has a name and a total quiz score. Supply an appropriate constructor and functions get_nameO, add_quiz(int score), get_total_scoreO, and get_average_scoreO. To compute the latter, you also need to store the number of quizzes that the student took. Exercise P5.10. Modify the Student class of Exercise P5.9 to compute grade point averages. Member functions are needed to add a grade, and get the current GPA. Specify grades as elements of a class Grade. Supply a constructor that constructsa grade from a string, such as "B+". You will also need a function that translates grades to their numeric values (for example, "B+" becomes 3.3)
