PROGRAM DESCRIPTION

In this project, you have to write a C$++$ program to keep track of grades of students using structures and files.

You are provided a data file named student.dat. Open the file to view it$.$ Keep a backup of this file all the time since you will be editing this file in the program and may lose the content.

The file has multiple rows$-$each row represents a student. The data items are in order: last name, first name including any middle names, student ID $(8$ digits long$),$ number of tests the student took, and the scores in those tests. Note that each item is separated by commas $(\text{'},\text{'}),$ even the last score has a comma after it$.$ Do not change this format.

The teacher has given $5$ tests to each student, but not all students took all $5$ tests. The minimum test score is dropped.

You are also provided a $.$cpp file: getNumber.cpp$.$ It has a single function getNumber which gets the number of student records in the data file. You will need to call this function to create your dynamic arrays.
