#NESTED LOOPS - loop inside the loop

#write a program that reads number of students in the major and for 
#each student program reads number of courses student takes in Fall 
#19. The program reads the grade for each course and finds 
#the average grade for each student in Fall 19

#Assume that number of students is positive and we will assume
#that each student takes at least one course

#We also want to find an average grade per major in Fall 19
