$6\mathrm{.}17$ LAB: 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 $20.$ 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: $x<mn\; id="EditorElement\_382285">6</mn><mn\; id="EditorElement\_382286">0</mn><mi\; id="EditorElement\_382288">D</mi>$:$60=$

$F$: $x<mn\; id="EditorElement\_382308">6</mn><mn\; id="EditorElement\_382309">0</mn>$

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.
