Page 514: #13.3 - Add an eraser feature to the Fig 13.3 drawing program
Page 514: #13.4 - Add an "Erase ALL" button to the Fig 13.3 drawing program
EXTRA CREDIT: Add a "Color Picker" to the Fig 13.3 drawing program allowing the user to select which color to use when drawing. (This does NOT have to be graphic, radio buttons or a drop down list is OK)
These exercises are cumulative - rather than handing them in separately, when complete, hand in one version demonstrating all of the features.
