Course Grade

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:
  • A: 90 =< x
  • B: 80 =< x < 90
  • C: 70 =< x < 80
  • D: 60 =< x < 70
  • 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 setprecision manipulator to format the output.

Ex: If the input of the program is:

StudentInfo.tsv

and the contents of StudentInfo.tsv 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 90 86 45 C

Averages: midterm1 83.40, midterm2 76.60, final 61.60
