Assignment 5 Linked List Template Class
Instructions In this assignment you will build upon the program worked on in the previous assignment. You are free to build upon your solution or start from the skeleton code provided. Task 1: Linked List Template Class Your first task is to replace the various Linked List collection classes in the code with a single LinkedList Template class that will be able to store any objects. As was done in class and your tutorials, you will create a LinkedList.h file that contains the class definition as well as the function definitions. Once implemented this template will be used in place of the CustomerList and VehicleList class (storing Customer and Vehicle pointers, respectively). Your LinkedList template must be consistent with the previously used classes (ie. must implement the same member functions and override the same operators). There is one function in the CustomerList class that we will not provide in our generic template, the get function. The only place this function is called from is the Shop class. Modify the getCustomer function in the Shop class that calls this get function so the functionality is preserved (ie. use the provided functions and operators provided by the LinkedList template to provide this functionality). You will also store pointers to the Mechanic objects in the Shop class in a LinkedList. In doing this you will need to look at the following: ● Update how the += operator works for Mechanic pointers in the Shop class ● Get rid of any data members or member functions that are no longer needed in the Shop class ● Update how certain member functions work in light of this change in the Shop class ● Update how mechanics are printed in the controller and view classes ● Overload the < and operators in the Mechanic class to compare objects based on salary. This is needed since the LinkedList inserts and stores its objects in sorted order.
Task 2: Vehicle Class Hierarchy You will now introduce a second inheritance hierarchy into your program. The base of this hierarchy will be the Vehicle class. You are free to change the access specifiers in this class as you see fit. You are to add a pure virtual to this class called toString that will return a string and update the overloaded output stream insertion operator to call to call the toString function as opposed to accessing the member variables directly. This will allow us to control how all derived classes in this hierarchy will be printed to screen (ie. allowing us to include class specific information). See the sample output for an example of this in use.
You will now introduce three derived classes to this hierarchy. The classes and the minimum of what you need to include in them are described below. ● The Car class will not introduce any further data members to those supplied by the Vehicle class. You will need to: ○ Include an appropriate constructor ○ Implement the toString function appropriately and make any other changes so that Car objects can easily be printed to screen. ● The Truck class will include everything described for the Car class as well as: ○ A new integer data member to keep track of the number of axles the truck has ● The Motorcycle class will include everything described for the Car class as well as: ○ A new boolean data member to indicate if the motorcycle has a sidecar or not
Task 3: VehicleFactory class You will now create a VehicleFactory class to implement the factory design pattern within your program. This class will offer three public functions, all called create which all return a Vehicle pointer. They will be differentiated by their parameter list: each version is responsible for creating a specific object in the Vehicle hierarchy and the parameters it takes are those needed to create the specific object in question. Once implemented, the header file for this class should be the only file in your entire program (other than the Car.cc, Truck.cc and Motorcycle.cc source code files) that includes the Car, Truck and Motorcycle headers . The rest of your program will interact with these objects using Vehicle handles. Update your ShopController class to include a VehicleFactory data member. This instance of your factory will be responsible for creating every instance of any object in the Vehicle hierarchy throughout your program. Update your initShop function in the ShopController class to use your factory to create vehicles of all types to your customer database.
Task 4: Update UI The last task is to update the user interface (and the associated view and controller classes) to take advantage of the new functionality. Specifically, when the user asks to add a vehicle and after prompting the user for the id, you must also prompt the user for which type of vehicle they want to add. Based on that, the appropriate information is asked for, the appropriate object is created (using your new VehicleFactory) and is added to that customer. As always, you must maintain the good design principles of this program, including the separation of the view, controller and model objects. See the sample output to see how this should work.
Constraints ● your program must not have any memory leaks (don’t worry if valgrind reports that some memory on the heap is “still reachable”) ● do not use any global variables ● your program must reuse functions everywhere possible ● your program must be thoroughly commented ● your program must compile and run in COMP2404-2406- W18 Virtual Machine
Submission You will submit in cuLearn, before the due date and time, one tar file that includes all the following: ● all source code, including the code provided ● a readme file that includes: ○ a preamble (program author, purpose, list of source/header/data files) ○ the exact compilation command ○ launching and operating instructions
Grading [out of 30 marks] Marking components: ● 11 marks: linked list template ○ 5 marks: overall structure ○ 1 mark: each for storing Mechanic, Vehicle and Customer objects using template ○ 1 mark: updated += operator for Mechanic objects in Shop class ○ 1 mark: for other appropriate updates to Shop class ○ 1 mark: for overloaded < and in Mechanic class based on salary ● 10 marks: Vehicle class hierarchy ○ 1 mark: for pure virtual toString function ○ 3 marks: for each Car, Truck and Motorcycle class structure ● 5 marks: VehicleFactory class ○ 3 marks: correctly implements each version of the create function ○ 2 marks: proper use in the ShopController class ● 4 marks: updates to UI
Notes: In order to get credit for a marking component, the program must prove that the marking component executes successfully. This is usually accomplished by printing out correct data.
Deductions ● Packaging errors: ○ 10% for missing readme ● Memory leaks: ○ 10% for any memory leaks in your program ● Major programming and design errors: ○ 50% of a marking component that uses global variables ○ 50% of a marking component that consistently fails to use correct design principles, including separate functions ○ 50% of a marking component where unauthorized changes have been made to provided code or prototypes ● Minor programming errors: ○ 10% for consistently missing comments or other bad style ○ 10% for consistently failing to perform basic error checking ● Execution errors: ○ 100% of a marking component that can’t be tested because the code doesn’t compile or execute in the VM ○ 100% of a marking component that can’t be tested because the feature isn’t used in the code ○ 100% of a marking component that can’t be proven to run successfully because data is not printed out
