a. Plan the logic for an insurance company program to determine policy premiums. The program continuously prompts the user for an insurance policy number. When the user enters an appropriate sentinel value, end the program. Call a method that prompts each user for the type of policy needed—health or auto. While the user’s response does not indicate health or auto, continue to prompt the user. When the value is valid, return it from the method. Pass the user’s response to a new method where the premium is set and returned—550ドル for a health policy or 225ドル for an auto policy. Display the results for each policy. b.Modify Exercise 9a so that the premium-setting method calls one of two additional methods—one that determines the health premium or one that determines the auto premium. The health insurance method asks users whether they smoke; the premium is 550ドル for smokers and 345ドル for nonsmokers. The auto insurance method asks users to enter the number of traffic tickets they have received...
