Sample Run #1:
This program computes average of exam grades
Enter new grade (Negative value if finished): 50
Enter new grade (Negative value if finished): 80

Enter new grade (Negative value if finished): 40

Enter new grade (Negative value if finished): -1

Average Grade of the class is 56.666666666666664
