A. Write a program to keeps records and performs statistical analysis for a class of 50 students. For each student you will have a 10-digit ID, 2 quizzes, 2 assignments, 2 lab tests, 1 test, 1 project and one final exam. The student data are to be stored in an array of student structures. This structure has the following fields: i) A string : id ii) 3 double arrays : quiz, ass, labTest 111) 4 double variables : test, proj, final, total iv) 1 char variable: grade. Provide for up to 50 students. The input is read from a text file. Each line in the file contain. a student ID and the scores for 2 quizzes, 2 assignments, 2 lab tests, 1 test, 1 project and one final exam, in order. Your program must calculate the total scores and assign a grade for each student based on the following table: Total Scores Grade 90<=total <=100 A 80<=total <90 60<=total <80 40<=total <60 below 40 F The program also calculates the total scores for quizzes, assignments and lab tests to be printed. Then it calculates the number of students who earned each grade, A to F. There are 4 functions involve in this system: а) main () Reads students' record (id, scores for 2 quizzes, 2 assignments, 2 lab tests,1 test,1 project, and final examination) from a file. b) studentGrade () Calculates total score and determines grade for each student and store them in total and grade fields of the structure. c) countGrade () Counts the number of students who earned each grade. d) outputResult () Calculates the total scores for quizzes, assignments and lab tests and print the output, which displays the report as shown below. The output will be displayed in an output file.

THE GIVEN NUMBER AT QUESTION PLEASE UNDERSTAND THE POINT AND CONNECTME INEED RIGHT ANSWER
Transcribed Image Text:A. Write a program to keeps records and performs statistical analysis for a class of 50 students. For each student you will have
a 10-digit ID, 2 quizzes, 2 assignments, 2 lab tests, 1 test, 1 project and one final exam. The student data are to be stored in
an array of student structures. This structure has the following fields:
i) A string : id
292
11) 3 double arrays : quiz, ass, labTest
ii1) 4 double variables : test, proj, final, total
iv) 1 char variable: grade.
Provide for up to 50 students.
The input is read from a text file. Each line in the file contain. a student ID and the scores for 2 quizzes, 2 assignments, 2
lab tests, 1 test, 1 project and one final exam, in order. Your program must calculate the total scores and assign a grade for
each student based on the following table:
Total Scores
Grade
90<=total <=100
A
80<=total <90
B
60<=total <80
40<=total <60
D
below 40
F
The program also calculates the total scores for quizzes, assignments and lab tests to be printed. Then it calculates the number of
students who earned each grade, A to F.
There are 4 functions involve in this system:
a)
main ()
Reads students' record (id, scores for 2 quizzes, 2 assignments, 2 lab tests,1 test,1 project, and final examination) from a file.
b) studentGrade ()
Calculates total score and determines grade for each student and store them in total and grade fields of the structure.
c) countGrade ()
Counts the number of students who earned each grade.
d) outputResult ()
Calculates the total scores for quizzes, assignments and lab tests and print the output, which displays the report as shown
below. The output will be displayed in an output file.
