Write a program that reads the student information from a comma separated values (csv) file. The program then creates a text file that records the course grades of the students. Each row of the file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student each separated by a comma. A sample of the student information is provided in StudentInfo.txt. Assume the number of students is at least 1 and at most 20. The program performs the following tasks: • Read the file name of the file from the user. • Open the text file and read the student information. • Compute the average exam score of each student. Assign a letter grade to each student based on the average exam score in the following scale: o A: 90 =< x o B: 80 =< x < 90

14.5 LAB^: Course Grade Write a program that reads the student information from a comma separated values (csv) file. The program then creates a text file that records the course grades of the students. Each row of the file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student each separated by a comma. A sample of the student information is provided in Studentlnfo.txt. Assume the number of students is at least 1 and at most 20. The program performs the following tasks: • Read the file name of the file from the user. Open the text file and read the student information. Compute the average exam score of each student. Assign a letter grade to each student based on the average exam score in the following scale: o A: 90 =< x o B: 80 =< x < 90 o C: 70 =< x < 80 o D: 60 =< x < 70 o F:x< 60 • Compute the average of each exam. • Output the last names, first names, exam scores, and letter grades of the students into a text file named report.txt. Output one student per row and separate the values with a tab character. • Output the average of each exam, with two digits after the decimal point, at the end of report.txt. Hint: Use the precision sub-specifier to format the output. Ex: If the input of the program is: StudentInfo.txt and the contents of Studentlnfo.txt are: Barrett,Edan,70,45,59 Bradshaw, Reagan, 96,97,88 Charlton, Caius,73,94, 80 Mayo, Tyrese, 88,61,36 Stern, Brenda,90,86,45 the file report.txt should contain: Barrett Edan 70 45 59 F Bradshaw Reagan 96 97 88 A Charlton Caius 73 94 80 B Mayo Tyrese 88 61 36 D Stern Brenda 06 86 45 Averages: Midterm1 83.40, Midterm2 76.60, Final 61.60
