Purpose: Practice with conditionals; practice with variables and good program design. Degree of Difficulty:MOD For this problem, you will write a program that will allow a user to calculate a letter-based grade, based on a grade percentage. Here is a description of how your program should look and behave: . Initially, text "Grade Calculator" and "Average: should be displayed on the canvas as seen in Figure 1. (Do not worry about matching exact color or size.) . When the user presses a key, show the keys pressed beside 'Average". . When the user clicks the mouse, show the calculated grade in the bottom right corner of the canvas. • If a grade is showing and the user clicks the mouse, reset the canvas, clearing both the grade and average text. (The canvas should looke like it initially did.) Grade Calculator Average: Grade Calculator Average: 65 Figure 1: The initial canvas ready for input (left). The canvas after a user presses 6 and 5 (middle). The canvas after the user clicks the mouse (right). Below is a table of which grade should be assigned to each average. Average 90 - 100 80 - 89 70 - 79 60 - 69 0-59 Grade Calculator Average: 65 D Grade A B D F Here are some suggestions for how to design your program, especially with regard to the Model-View- Controller design pattern. • You will want to use at least 2 global variables in your program: these are the current keys pressed and the grade to be displayed. • You should have a function that takes an average as a parameter. This function should have condi- tionals to determine the appropriate grade and return it. • Your keyPressed() function should update your global keys pressed variable. • Your mouseClicked() function should have a conditional. It will either calculate an appropriate grade. or reset the canvas.
