12. Used Car Dealership Inventory Your task is to create a simple text-based "Console Application" in C# to maintain a catalog of used cars. The catalog keeps track of each car's make, model, year, and sale price. The program begins with an empty catalog. The user is prompted to enter one of three possible commands: add -add a car to the catalog list -list all cars in the catalog quit -quit the application If an unknown command is entered, the user should be informed and asked to enter another command. If the add or list commands are entered, the operation for that command is carried out, then the user is prompted for another command. The application continues until the quit command is entered. The add command If the add command is entered, the user will then be prompted to enter the car's make, model, year, and sales price, one-by-one. The make (e.g. Isuzu) and model (e.g. Trooper) can be arbitrary strings, while the year (e.g. 1990) should be an integer and the sales price (e.g. 2599.99) should be a floating point value. After the data is entered, the record should be stored in memory to be recalled later by the list command. You may assume that the catalog will never hold more than 20 cars. You are not required to do any error checking on the data that is entered. For the purpose of keeping the assignment simple, the program may behave arbitrarily badly if the user enters improperly formatted input. The list command If the user enters the list command, the contents of the catalog should be displayed to the screen, nicely formatted. The format of the output should resemble the example trace below. Regardless of the precision of the stored sales price, the value should be formatted in dollars and cents. If no

C# .NET Assignments


items exist in the catalog, the command should output a message stating so. Otherwise, after printing out the details of each car, the number of cars and total price of all cars should be printed. Example program trace Welcome to Mullet Joe's Gently Used Autos! Enter command: show Sorry, but "show" is not a valid command. Please try again. Enter command: list There are currently no cars in the catalog. Enter command: add Make: Volkswagen Model: Jetta Year: 1999 Sales Price ($): 9450 Enter command: add Make: Toyota Model: Prius Year: 2006 Sales Price ($): 27999.90 Enter command: list 1999 Volkswagen Jetta $9,450.00 2006 Toyota Prius $27,999.90 Number of cars: 2 Total inventory: $37,449.90 Enter command: quit Good bye! Extending the assignment For extra practice, feel free to extend this assignment in any way that you choose. Some exampleextensions include adding a "delete" command or the ability to sort the cars in the catalog by yearor price.

13. An electricity board charges the following rates to domestic users to discourage large consumption of energy.

For the first 100 units -40 P per unit For the next 200 units 50 P per unit Beyond 300 units -60 P per unit

14. A bookshop maintains the inventory of books that are being sold at the shop. The list includes details such as author, title, price, publisher and stock position.

C# .NET Assignments


is available or not. If it is not, an appropriate message is displayed. If it is, then the system displays the book details and requests for the number of copies required, If the requested copies are available, the total cost of the requested copies is displayed; otherwise the message Required copies not in stock is displayed. Design a system using a class called books with suitable member functions and constructors, Use new operators in constructors to allocate memory space required.
