Looks like programming class is starting to pick up. Today we learned something new for multi-dimensional arrays. All this week we been working with arrays. From 1D arrays to 2-D arrays even 3-d arrays. We reviewed things like how to read in all the data for 2-D and 1-D arrays, change a particular mark, change all the numbers, check the range, find the largest number and total of numbers. To increase and decrease marks and find averages. This also involves reading in IO Files.
