Question

The program should do the following to each test score

entered:

1. display a count of the total number of scores

entered,

2. display an average of all test scores entered

3. and display the highest test score entered

You can start new by pressing the clear button, or exit by

pressing the exit button.

Please fix my code so that it does as required. It

currently just keeps the count at "1" and average and best scores

as the entered test score. Thank you.
