   9 Requirements:
  10
  11 Create a class called STUDENT with data members firstname, lastname, age finalcwgrade and
  12 finalexgrade and studentID.
  13 Use a default constructor to initialize firstname to “Usain” and lastname to “Bolt”.  Initialize
  14 all other data members to zero.
  15 Define a mutator that will accept values for the data members from the user and update each data
  16 member.
  17 Define a function CalculateFinalGrade that will sum the final coursework grade and the final exam
  18 grade and return the average of both grades.
  19 Define a utility function that will check if the final grade is above 80, and prints the message
  20 “This student is above average”. If the final grade is not above 80, then your program should
  21 display “ This is an Average Student”  This utility should be invoked by a display function.
  22 The display function will display all the student’s information and whether or not the student is
  23 average or above average.
  24 Finally, write a main program that will implement the student class. Invoke the display function
  25 before the user enters inputs to display default constructor values and should also be invoked
  26 after the user inputs.
