That’s okay because you don’t need to worry about makinga program that executes in a second or two any faster anyway. Adding theloop causes the program to take a few seconds to complete.In addition, I removed the output statements. You quickly discover that outputis a very slow process. The time spent outputting information to the screenwould have swamped everything else.When executed, the program opened a Console window for a few minutesand then closed the window. Not very exciting so far. I then selectedExecute➪Profile Analysis. The window shown in Figure 30-1 appeared.
