ALICE PROGRAMMING

1. Unless nested within a repeating control structure, Do in order, Do together, and If/Else control statements are expected to be executed exactly how many times?

2. Give two examples of control structures that are generally expected to execute repeatedly.

3. If a block of program code is composed of nested Loop statements and the outer loop count is 3 and the inner loop count is 5, how many times does the inner loop execute?

4. A Loop in which the count is infinity must of course, eventually stop. What action triggers the stop of a so-called infinite loop?

5. What distinguishes a Loop control construct from a While control construct, in terms of what is known about the number of times a block of code will be repeated?

6. Conditional expressions used in a While statement have the same components as conditional expressions used in what other control construct?

7. Is it possible that the instructions within a While statement might never be executed at all? If not, explain why not. If so, give an example.
