Write a program that asks the user to enter a student's name and 8 numeric assignment scores (out of 100 for each assignment). the program should output the students name, a letter grade for each assignment score, and cumulative average for all the assignments. note, there are 12 students in the class so your program will need to be able to either accept data for 12 students or loop 12 times in order to process all the students in the class.

write the following functions in the program:
calc_average - this function should accept 8 assignment scores as arguments and return the average of the scores
determine_grade - this function should accept an assignment score as an argument and return a letter grade for the score based on the following grading scale:

90-100 a
80-89 b
70-79 c
60-69 d
below 60 f
