#Write a program that reads number of courses and final grade for 
#each course, and finds the average final grade for the academic 
#year. 


#input: num_courses, integer, grade for each course
#calculations: loop while, need to accumulate sum of all grades
#average=sum/num_courses

#Version 1: everything in main
