Question

Suppose a teacher weights the four
exams he gives 10%, 25%, 30%, and 35%. Write a
program that reads ten sets of four grades.
i just need an explaination on how I would write the code to read ten sets of four grades. It is also supposed to be a global variable

Answer 1

Depends on if the list is sorted 10x10x10x10 or 4x4x4x etc.

Either way it seems like setting up a for loop to handle it should be appropriate.

For the first, I'd do a for loop with 10 iterations nested within another with 4 iterations.
For the second, I'd (depending on where you're reading the data from) do a single loop with 10 iterations and scoop all four variables in one go, or do a 4-iter loop within a 10-iter loop.
