Course Grade

Write a program that reads the student information from a tab separated values $($tsv$)$ file.

The program then creates a text file that records the course grades of the students. Each row of the tsv file contains the Last Name, First Name, Midterm$1$ score, Midterm$2$ 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 $20.$ Assume also the last names and first names do not contain whitespaces.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: $90=<$ xB: $80=<$ 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.tsvand the contents of StudentInfo.tsv are: Barrett Edan $704559$Bradshaw Reagan $969788$Charlton Caius $739480$ Mayo Tyrese $886136$ Stern Brenda $908645$ the file report.txt should contain: Barrett Edan $704559$ FBradshaw Reagan $969788$ ACharlton Caius $739480$ BMayo Tyrese $886136$ DStern Brenda $908645$ CAverages: midterm$183\mathrm{.}40,$ midterm$276\mathrm{.}60,$ final $61\mathrm{.}60$
