Answers to Hour 15
| 1: | True or False: You have to know the start and end values of a for loop at design time to use this type of loop. |
| A1: | False. You must know these values at runtime, but it isn't necessary to know them at design time. |
| 2: | Is it possible to nest loops? |
| A2: | Yes, and this is a common thing to do. |
| 3: | What type of loop would you most likely need to create if you didn't have any idea how many times the loop would need to occur? |
| A3: | do…while |
| 4: | If you evaluate the expression in a do…while on the while statement, is it possible that the code within the loop may never execute? |
