Question
A university is analysing students' academic performance in a course using an application. As shown below, the application generates a list of final marks and an academic performance reрort: The following information is required to generate the final mark listing and academic performance report: Course details The course details to be stored in the program include a list (array) of final marks, number of students, a list (array) of the distribution of frequencies of grades. The final marks are stored in a text file named marks.txt. Download the data file, marks.txt from WBLE for building the list of final marks in the program. The final marks: 75B+ 79B+ 88A 96A+ 90A+ 80A 76B+ 76B+ 79B+ 76B+ 75B+ 91A+ 92A+ 82A 84A 76B+ 97A+ 93A+ 95A+ 82A 78B+ 81A 81A 82A 77B+ 75B+ 85A 63B 67B 71B+ 73B+ 73B+ 72B+ 68B 74B+ 69B 73B+ 68B 62B 61B 68B 70B+ 66B 61B 62B 64B 62B 71B+ • Listing the final marks with associated grades After building the list of final marks in the program, all the final marks and associated grades are listed with no more than 8 numbers on a line as shown in Diagram 1. Table 1 shows the grading system: 69B 66B 69B 61B 74B+ 68B 60B 62B 71B+ 73B+ 66B 72B+ 70B+ 67B 69B 65B 72B+ 61B 60B 63B 61B 61B 66B 69B 58C+ 56C+ 56C+ 520 55C+ 55C+ 500 55C+ 56C+ 54C 59C+ 57C+ 54C 52C 510 58C+ 59C+ Table 1: Grading system. 500 59C+ 51C 55C+ 53C 540 54E 31F 54C 25F 25E 19F 10F 42F 22F Mark Range 90 - 100 80 - 89 70-79 60-69 55-59 Grade A+ Total number of students: 104 A B+ The Success Institute В SLLM 1643 Laws of Leadership Mastermind Academic Performance Report C+ C F 50-54 0-49 Grade | No. of Student | Percentage | Histogram (Percentage) • Generating the distribution of frequencies of grades The application determines how many students score an A+, how many students score an A, how many students score an B+, how many students score a B and so on for all grades.
