Problem Suppose at the end of the semester, there is a file "scores.dat" recording scores each student has earned so far from closed lab assignments (CLA), open lab assignments (OLA), quizzes, exams, and final exam score. You can assume there are no more than 30 students. The final letter grade is decided according to the following table based on the total points they have earned: Total Points Final Letter Grade Total Points Final Letter Grade >=90 A >=70, but <73 C- >=87, but <90 B+ >=67, but <70 D+ >=83, but <87 В >=63, but <67 D >=80, but <83 В- >=60, but <63 D- >=77, but <80 C+ <60 F >=73, but <77 In this assignment, you are asked to write a program to calculate student final letter grades as well as the average and highest scores of CLA, OLA, quizzes, exams, and final exam scores, respectively. The final result should be printed to the screen (standard output). Requirements: • You must use the language you picked from projectl. • At the beginning of the program, your program should give the user a prompt for the name of the data file which contains the records of student grades. • Define a class Student, which includes student id, scores for CLA, OLA, quizzes, exams, final scores, total points, and letter grade. All member data must be private. The class must provide a function to calculate the final letter grade. • Define a class Roster, which has an associative array (other similar data structures like map, hash map are also fine) to store all Student objects. Define appropriate methods in the class to calculate, update, and query individual student information as well as required statistic information of all students. • Your program should allow users to perform two queries. For each query, the user inputs C#, and your program should print all information (including his/her final letter grade) of the student with the given C#. After two queries, your program print information of all students as well as the average and highest scores of CLA, OLA, quizzes, exams, and final exam on the screen.

Transcribed Image Text:Problem : Suppose at the end of the semester, there is a file "scores.dat" recording scores each student has
earned so far from closed lab assignments (CLA), open lab assignments (OLA), quizzes, exams, and final
exam score. You can assume there are no more than 30 students. The final letter grade is decided according to
the following table based on the total points they have earned:

In this assignment, you are asked to write a program to calculate student final letter grades as well as the
average and highest scores of CLA, OLA, quizzes, exams, and final exam scores, respectively. The final result
should be printed to the screen (standard output).
Requirements:
• You must use the language you picked from project1.
• At the beginning of the program, your program should give the user a prompt for the name of the
data file which contains the records of student grades.
• Define a class Student, which includes student id, scores for CLA, OLA, quizzes, exams, final scores,
total points, and letter grade. All member data must be private. The class must provide a function to
calculate the final letter grade.
• Define a class Roster, which has an associative array (other similar data structures like map, hash
map are also fine) to store all Student objects. Define appropriate methods in the class to calculate,
update, and query individual student information as well as required statistic information of all
students.
• Your program should allow users to perform two queries. For each query, the user inputs C#, and
your program should print all information (including his/her final letter grade) of the student with the
given C#. After two queries, your program print information of all students as well as the average and
highest scores of CLA, OLA, quizzes, exams, and final exam on the screen.
