Chapter 3, Problem 3AW
Look at the following description of a problem domain:
The bank offers the following types of accounts to its customers: savings accounts, checking accounts, and money market accounts. Customers are allowed to deposit money into an account (thereby increasing its balance), withdraw money from an account (thereby decreasing its balance), and earn interest on an account. Each account has an interest rate.
Assume that you are writing an application that will calculate the amount of interest earned for a bank account.
- a. Identify the potential classes in this problem domain.
- b. Refine the list to include only the necessary class or classes for this problem.
- c. Identify the responsibilities of the class or classes.

5. Joe’s Automotive
Joe’s Automotive performs the following routine maintenance services:
• Oil change—$26.00
• Lube job—$18.00
• Radiator flush—$30.00
• Transmission flush—$80.00
• Inspection—$15.00
• Muffler replacement—$100.00
• Tire rotation—$20.00
Joe also performs other nonroutine services and charges for parts and labor ($20 per
hour). Create an application that displays the total for a customer’s visit to Joe’s.
The form should resemble the one shown in Figure 6-31.
The application should have the following value-returning methods:
• OilLubeCharges—Returns the total charges for an oil change and/or a lube job,
if any.
• FlushCharges—Returns the total charges for a radiator flush and/or a transmission flush, if any.
• MiscCharges—Returns the total charges for an inspection, muffler replacement,
and/or a tire rotation, if any.
• OtherCharges—Returns the total charges for other services (parts and labor),
if any.
•…

C# programming question.
This task will be a car dealership where you’ll help the user find the car(s) they want. This program should keep going until the user either decides to not continue with the purchase, or the purchase is complete, and no more order is being processed. You will need 3 structs to store: • client information • order information • used_car information Each struct would have the following fields: struct used_car { int carID; char brand[length]; char make[length]; int year; int mileage; float price; }; struct order { int numCosigned; int carID; float pricePerPerson; }; struct client { char firstName[length]; char lastName[length]; bool isEmployed; int creditScore; }; I. global variables: • Create an array of struct used_car and add some cars in there. I put 4 cars. You can do as many as you want (at least 3). • Make sure to put the struct definition above the array creation, otherwise, it won’t work. o This is similar to you trying to call a function X that’s not…

Tip: You will need to import functionality from the datetime module to do this. Create a class named Truck that inherits from the Vehicle class. This class should have an additional attribute, max_load, which represents the maximum load capacity of the truck.
