As a concluding exercise for this chapter, we will develop a pop-up eliminator application. If you have used the World Wide Web, you probably are already familiar with pop-ups, as shown in Figure 7.2. These additional windows display ads or other information in a separate Internet Explorer window, which must be closed to avoid cluttering up the screen. To help eliminate this nuisance, we will write a sample program that will automatically close these windows for you. In doing so, we will use several types of decision and control statements, including the If statement and several types of loops.
