Lab Description : Instantiate an array, load it with values. Find the total, average, max, and min. Sample Data : 100 90 85 72.5 95.6 50.0 100.0 80.0 93.4 -90.0 90.0 1 2 3 4 5 6 7 8 9 Sample Output : grade 0 :: 100.0 grade 1 :: 90.0 grade 2 :: 85.0 grade 3 :: 72.5 grade 4 :: 95.6 total = 443.1 average = 88.62 maximum = 100.0 minimum = 72.5 average with dropped lowest = 92.65 WOW! Your average went up 4.03 points! *************************************************** grade 0 :: 50.0 grade 1 :: 100.0 grade 2 :: 80.0 total = 230.0 average = 76.67 maximum = 100.0 minimum = 50.0 average with dropped lowest = 90.0 WOW! Your average went up 13.33 points! *************************************************** grade 0 :: 93.4 grade 1 :: -90.0 grade 2 :: 90.0 total = 93.4 average = 31.13 maximum = 93.4 minimum = -90.0 average with dropped lowest = 91.7 WOW! Your average went up 60.57 points! *************************************************** grade 0 :: 1.0 grade 1 :: 2.0 grade 2 :: 3.0 grade 3 :: 4.0 grade 4 :: 5.0 grade 5 :: 6.0 grade 6 :: 7.0 grade 7 :: 8.0 grade 8 :: 9.0 total = 45.0 average = 5.0 maximum = 9.0 minimum = 1.0 average with dropped lowest = 5.5 WOW! Your average went up 0.5 points! *************************************************** Computer Science I Lab07A GRADES Lab Value - 100
