DOTILASOFAMIREDO

2. This may look like the same centered display of the 80 point version, but there is a major difference.In the 80 point version, all of the words show up at once. In the 90 point version, the words show upone at a time starting with the bottom DO and working its way up to the top DO. There should be aone second pause between each word.

02d 100 Point Version

1. Your program block must display these 8 lines of output:

DOTILASOFAMIREDO

2. The 100 point version has major changes. Like the 90 point the words are still displayed one at a time going up; however, as each word is displayed, the previous word must be cleared. On the way up only one word should be visible at a time. After you get to the top DO the words needs to be displayed in reverse order goingdown. This time the output will not be clear. When finished, the output will show all 8 words for 5 seconds.
