Here are the marks for a class. I want the total, the average,
the highest, and how many are above the pass mark. And I do
not want to retype anything when a student joins.
Write your requirements list before you write any code.This set also asks you to name the table and the function before you start — what is in the table, and what your function takes and does.
Notes
Terminal or window, your choice. Say which in your requirements list.
Four answers, one table, and every one of them is a traversal. Write the first one carefully and the rest are the same shape.
The highest is the interesting one. You cannot compare against nothing, so what does the running best start at, and why?
total / #scores is the average, and Lua's / does not truncate. Decide what you want displayed.
Not retyping anything is the actual requirement. Adding a mark should mean adding a number and nothing else.
What Success Looks Like
Adding a score to the table changes every answer, with no other edit
All four answers are correct for a table you worked out by hand
The accumulators are above the loops, not inside them
An empty table does not produce nonsense — or you have said what it does
Check it against a table of three numbers you can do in your head. Then add a fourth and check again.
