the course grades of the students. Each row of the tsv file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student. A sample of the student information is provided in Studentinfo.tsv. 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 tsv file from the user. • Open the tsv 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 þf 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.
