For this assignment, implement a high score system using a sorted list data structure to

sort scores from highest to lowest. Your program should print out a list of scores, ask the

user for a new score, insert the new score in the correct position, print out the new score

list, and let the user keep entering scores and displaying the sorted list until the user quits.

If you wish, you can seed the high score list with a few dummy scores, ala vintage arcade

games, or just start with an empty sorted list.

Unlike vintage arcade games, we are just storing the scores and not associated names or

initials of who got the score.

I have placed an incomplete sorted list implementation called SortedListHasA on a shared

folder for you to use for this assignment:

It uses the containment $/$ "has A$"$ scheme discussed in the book and in class; namely, it has

a basic linked list as part of its private member data, and then adds some methods in order

to implement the sorted list operations.

Familiarize yourself with the code. The compilation instructions to get running on hills $$

are similar to the instructions for the earlier LinkedList assignment, except you need to

work with the codebase for SortedListHasA.zip instead of LinkedList.zip.

Pay particular attention to the member function getPostion$()$ in SortedListHasA.cpp$,$ which

is wrong. As implemented, this function always returns $1.$ As a result, many of the tests

called from main$()$ fail and an exception is thrown.

For this assignment, you'll need to do the following:

In SortedListHasA.cpp$,$ implement getPosition$()$ so that it works correctly. It should

return either the position of the given entry, if it occurs in the sorted list, or the position

where the entry would occur, but as a negative integer. Once you have this working, you

can verify that it works by checking that the tests pass.

Once you're confident it works, comment out the calls to various tests from main$(),$ and instead implement the high score system described above. if the user enter a negative score, the program should end.

Here is the SortedListHasA.cpp

CAN YOU TELL ME WHAT DOES THE ERROR MESSAGE MEAN AND HOW TO FIX IT$?$ THANK YOU

Thank you for your big help. I was able to fix the code. However, the Output was from the Low Score to Hight Score. What it neees to be done for this so it can be from High Score to Low Score? the main$()$ cpp and the output below. Thank you.
