4) Write me a program. This program should have three buttons labeled 'Seat Belt', 'Antilock Brakes', and 'Engine'. When you click on the button it should disappear. When you click where the button was, it should reappear. You get one point for every task below.

5) Write me a program. This program should have two buttons and a slider bar. The buttons should be labeled "Full" and "Less". The slider bar should have a 'F' to the left and a 'E" to the right. When the 'Full' button is pressed, the slider bar should be fully left. If the 'Less' button is pressed, the slider bar should move right. It should be impossible to go below empty. You get one point for every task below.
