I suggest you conceptualize the problem into 3 sub-problems:
- IO
- average computation
- validation (between 0 and 100)
For starters ignore validation.
So we only have IO + computation
ie Input then computation then Output
Now if your input needs to feed into a computation you need a *data-structure*
I suggest you consider lists
eg the 5 scores
4
2
1
3
5
would be represented as the list [4,2,1,3,5]
Their average -- 3 -- is to be *computed* and then to be given back to the user
-- ie *output*
Does this help start you off?
