Instructions In this assignment you will essentially convert the program you created in Assignment 1 into a program written in C++ using classes and object oriented design principles. A large part of this program has been provided to you to build from. It was designed using the modelviewcontroller design pattern that you should be familiar with. The various classes are described below. Controller The ShopController class acts as the controller for this program. It is the only class used by our main function (in main.cc). It maintains the model as well as the view. It prompts both the user for information and displays information via the View class (described below) and modifies the various model classes as appropriate. View The View class as the view for this program. All interaction with the user (including both input and output) is done using the view. These actions are prompted by the controller who then modifies the model in response. Model The Model is made up of a number of different classes. The Shop class will collect all of the objects that make up this automotive business. Currently it will only contain a list of customers ( Customer class). Each of these customers will contain a list of vehicles ( Vehicle class). These
Task 2: Finish the Program Your program must use the provided skeleton code without making any changes to the existing code, data structures or function prototypes. You will, however, add your own code to it. Below are the required changes you must make to for your program. 1. Customer and Vehicle classes You are to implement all of the member functions declared in the respective header files for these classes. Some notes on what is expected for the Vehicle class: The constructor simply sets all of the data members to the parameters passed in. The getter functions are simple, one line getters. Some notes on what is expected for the Customer class: The static member nextId is used to give all of the Customer objects unique IDs. Initialize it to 1000. The constructor sets the id member to the current value of the static member nextId , increments nextId and then simply sets all of other data members to the parameters passed in. The getter functions are simple, one line getters. The addVehicle function simply called the add function in the VehicleArray class (described below). It returns what this add function returns. 2. CustomerArray and VehicleArray classes These classes are collection classes that will store multiple Customer and Vehicle objects, respectively. Implementing this in a separate class will allow us to modify the data structure used at a later date without having to make changes to other classes (as we will do on a future assignment). These classes are very similar. Some notes on what is expected for both classes: The constructor simply initializes the size data member properly, The destructor must iterate over the stored objects (which are to be dynamically allocated, discussed below), freeing the allocated memory for each one. The getSize function is a simple, one line getter. The add function takes a pointer to a dynamically allocated object. It checks if there is room in the array of pointers for this object. If not, it returns C_NOK (defined in defs.h). If there is, it sets the appropriate pointer in the array to point at the same object as the parameter, increments the size data member and returns C_OK (also defined in defs.h). The get function takes an index value. If this index is not valid (ie. it is outside of the range of valid objects being stored), the function returns 0. Otherwise it returns the pointer at index i. 3. ShopController class The ShopController class contains a function called initCustomers which we will use to populate the program with data. This function will create dynamically allocated objects. It will work as follows. First it will create a Customer object followed by several Vehicle objects. You will add the Vehicle objects to the Customer using the Customers addVehicle member function. Once a Customer object has had all of its Vehicles added, you will add the Customer to the Shop object using its addCustomer member function. You will do this until the data fill requirements have been met. You will add 6 Customers to the shop. All of your customers must have at least one vehicle registered. On top of this, you are to have at least one customer with 2 vehicles, at least one customer with 3 vehicles and at least one customer with 4 vehicles. Once these three implementation tasks have been completed you should be able to compile and run the program. The main menu currently only has the option to print customers, which should work. Constraints you must use the function prototypes exactly as stated your program must not have any memory leaks (dont 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 the provided Virtual Machine
