| Question: Would I have to do anything besides change the conditions inside the if statements for the first question? On a test would we have to do a while loop since you gave a for loop? |
- For this question all you really have to do is to change the conditionals though you could change the for loops to while loops if you desired. If we want you to do anything as a requirement for the problem, it would be clearly stated in the problem itself. Dawn Finney.
