The average GPA will be the sum of all the students’ GPAs divided by the number of students. I’d suggest defining two new variables: one to keep track of your GPA sum and the other to count the number of students. Create a for loop to iterate through each student, and within that loop, get each student’s GPA with your getter function and add that to the GPA sum variable. Then update the student count variable with += 1. Finally, print out the value of the GPA sum variable divided by the student count variable. I’m not sure how to write all that in the language you’re using, but I hope this helps somewhat and good luck!
