Question (Arrays/Lists)

A teacher uses 2   arrays (or Lists) to keep track of his students. One is used to store student names and the other stores his grade (0-100). Write a program to create these two arrays (or lists) that are originally empty, and do the following using a menu:

1. Add a new student and his/her grade.

2. Print the name and grade of all current students, one student per line.

3. Display the number of students.

4. Print the names of students with a grade more than 90.

5. Raise the grades of all students by 5 points.

6. Exit.
