When the user presses the Enter key, the Click event of the Add button should fire. When the user presses the Esc key, the Click event of the Exit button should fire 3. Declare a class variable for an array that can hold up to 20 scores and an index variable that you can use to assign scores to elements of the array as well as keep count of how many scores are entered 4.
