COMP 121 In-Class Assignment

September 5, 2008

1. If you like, you may do this exercise with a partner.

2. You’ve done Tutorial 3-5 and saved it. Open that world now (it should be the one with the snowman and snowWoman, where he asks her if she comes there often). Add instructions at the end of the program to make it do the following:

a. Have the snowman ask the snowWoman if she wants to order a pizza

b. Add a variable named wantPizza and ask the user if the snowwoman wants a pizza

c. If the user says the snowWoman does want a pizza, she should say Sure!; otherwise, she should say No, thanks.

d. Add more instructions to the part where she does want a pizza. In that case, the snowman should ask the user what diameter pizza they should order. He should then calculate the area (remember, the area of a circle is πr², and you calculate the radius r by dividing the diameter by 2), divide it by 2 and say (for example), If we order a 12 inch pizza, we each get 56.519999999 square inches!
