Question: Ferd wants a circle drawing program, where he can move his mouse to a position and place a circle with a chosen radius and color. However, he has a little problem: his mouse is old and the buttons no longer work properly. He would like to ask you to implement a drawing program that allows him to use his old broken mouse and keyboard as follows: When space is pressed a circle should be placed at the current mouse position When the up arrow is pressed, the radius of the circle to be placed next increases by 5 When the down arrow is pressed, the radius of the circle to be placed next decreases by 5, but the radius never drops below 5. When the "c" key is pressed, the color of the circle to be placed next changes by cycling through the following colors: purple, red, green, blue, pink, and back to purple. The program should display the current color and circle radius in the top left corner. See this example: draw-circle demo Exercise 6 Design the structural data for the world state of the circle drawing program. Ask yourself, what changes during the lifetime of the program?
