"""
You are given two classes, Person and Student, where Person is the base class and Student is the derived class. Completed code for Person and a declaration for Student are provided for you in the editor. Observe that Student inherits all the properties of Person.

Complete the Student class by writing the following:

1.A Student class constructor, which has  parameters:
2.A string, firstName .
3.A string, lastName.
4.An integer, id.
5.An integer array (or vector) of test scores, scores.
6.A char calculate() method that calculates a Student object's average and returns the grade character representative of their calculated average: O,E,A,P,D,T
