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, 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:
A: 90= B: 80=< X < 90
C: 70=< X < 80
D: 60=< X < 70
E: 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: midtermi 83.40, midterm2 76.60, final 61.60

Buddys machine shop has a kiosk computer located in the lobby for customers to use. The kiosk computer has recently been updated to Windows 10 from Windows 7 and is not part of a domain. The local computer policy created for Windows 7 has been applied to Windows 10. This policy severely restricts the use of the computer, so that customers can only use the web browser.
Occasionally, an administrator needs to sign in to the kiosk computer to perform maintenance and update software. However, this is awkward because the administrator needs to disable settings in local policy be performing any task. Then, when the tasks are complete, the administrator needs to re-enable the settings in the local policy. Explain how this system can be improved upon.

If your PC's are in an Active Directory domain, you can leverage Active Directory Group Policies to deploy the appropriate settings. Be sure to include the below settings in your Group Policy for the user accounts and workstations that will be running as a Kiosk. After creating this Group Policy, you can test by running gpupdate /force and then restarting the PC.

User Configuration
Administrative Templates
Start Menu and Taskbar
Change Start Menu power button (enabled) - set to "Lock" (I know this sounds weird, but Windows 7 won't completely disable Logoff if the Start Menu power button is defaulting to the Logoff action).
Remove Logoff on the Start Menu (enabled)

Note that you may be able to automate the changes via the use of operating system imaging tools and local mandatory user profiles - leave a comment below if you have interest in those steps.

Login at each Kiosk PC using a user account that will ultimately be used to run the Kiosk desktop applications.
