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:
- A string : id
- 3 double arrays : quiz, ass, labTest
- 4 double variables : test, proj, final, total
- 1 char variable: grade.
Provide for up to 50 students.
The input is read from a text file. Each line in the file contains 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 |
C |
|
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.

- Falling Distance When an object is falling because of gravity, the following formula can be used to determine the distance the object falls in a specific time period:
d = 1/2 gt2
The variables in the formula are as follows: d is the distance in meters, g is 9.8, and t is the amount of time, in seconds, that the object has been falling. Write a function named fallingDistance that accepts an object’s falling time (in seconds) as an argument. The function should return the distance, in meters, that the object has fallen during that time interval. Write a program that demonstrates the function by calling it in a loop that passes the values 1 through 10 as arguments and displays the return value
