Write a C++ Program:

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_name(), add_quiz(int score), get_total_score(), and get_average_score(). To compute the latter, you also need to store the number of quizzes that the student took. Then, modify the Student class 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 constructs a grade from a string, such as "B+". You will also need a function that translates grades into their numeric values (for example, "B+" becomes 3.3).
