Write a
You need to use a while loop to allow the user to enter numbers, one at a time, until some numeric sentinel value is entered. I recommend having a sentinel like 9999, something unlikely to be confused with an exam score. If the user enters a score < 0 or > 100 that is not the sentinel value then that score is to be rejected. Each time a legit score is entered, however, it should be added (appended) to a list.
Once the user has entered all the numbers they want, calculate and display the average of the scores rounded to 1 decimal place.
I attached my solution. I can not fix two problems: 1. It does not count right the number of iterations and avg. 2. After I type 9999(sentinel value) it gives me output: Score is not in range. Please re-enter. It supose just quit and calculate the avg. Thank you!
