Display the total received points for the logged in student - this functionality should be available only for students 8. Display the highest/lower score received by students. Also the names and surnames of the students who received these scores should be displayed - this functionality should be available only for tutors 9. Terminate the program ……………………………………………………………………………………………………… 

 

When the application is started, this question should be displayed: 

Are you a tutor or a student? 

If the user’s answer is “tutor”, than the tutor password is required -> if the password is correct, then the application menu (for tutors) is displayed:

Display all the data for a given student found by his/her student_id 5. Display all the questions from file “question.txt” (only the question_text) 6. Display the highest/lower score received by students. Also the names and surnames of the students who received these scores should be displayed - this functionality should be available only for tutors 7. Terminate the program If the given password is not correct no menu is displayed and the application is terminated.
