C++ My code is at the bottom. I'm passing some of the test cases, but not all of them. I'm not sure what I need to change.

3.28 LAB*: Program: Online shopping cart (Part 2) This program extends the earlier "Online shopping cart" program. (Consider first saving your earlier program). (1) Extend the ItemToPurchase class per the following specifications: Parameterized constructor to assign item name, item description, item price, and item quantity (default values of 0) (1 pt) Public member functions o SetDescription() mutator & GetDescription accessor (2 pts) PrintItemCost() - Outputs the item name followed by the quantity, price, and subtotal o Printltem Description() - Outputs the item name and description . Private data members o string item Description - Initialized in default constructor to "none" Ex. of PrintItemCost output: Bottled Water 10 @ $1 = $10 Ex. of PrintItem Description() output: Bottled Water: Deer Park, 12 oz. (2) Create three new files: . Shopping Carth-Class declaration Shopping Cart.cpp - Class definition main.cpp - main() function (Note: main)'s functionality differs from the warm up) Build the Shopping Cart class with the following specifications. Note: Some can be function stubs (empty functions) initially, to be completed in later steps. Default constructor Parameterized constructor which takes the customer name and date as parameters (1 pt) Private data members o string customerName - Initialized in default constructor to "none" o string currentDate - Initialized in default constructor to "January 1, 2016" o vector - cartItems Public member functions o GetCustomerName() accessor (1 pt) o GetDate() accessor (1 pt) o Additem Adds an item to cartitems vector. Has parameter Item ToPurchase. Does not return anything. o Removeltem Removes item from cartitems vector. Has a string (an item's name) parameter. Does not return anything. If item name cannot be found output this message: Item not found in Not removed. o Modifyltem Modifies an item's description, price, and/or quantity. Has parameter Item ToPurchase. Does not return anything. If item can be found (by name) in cart, check if parameter has default values for description, price, and quantity. If not, modify item in cart If item cannot be found (by name) in cart, output this message: Item not found in cart. Nothing modified. o GetNumltemsInCarto (2 pts) Returns quantity of all items in cart. Has no parameters. o GetCostOfCart0 (2 pts) Determines and returns the total cost of items in cart. Has no parameters. o Print Total Outputs total of objects in cart. If cart is empty, output this message: SHOPPING CART IS EMPTY o PrintDescriptions Outputs each item's description. Ex. of Print Total output: John Doe's Shopping Cart - February 1, 2016 Number of Items : 8 Nike Romaleos 2 @ $189 = $378 Chocolate chips 5 @ $3 = $15 Powerbeats 2 Headphones 1 @ $128 = $128 Total: $ 521 Ex. of PrintDescriptions() output: John Doe's Shopping Cart - February 1, 2016 Item Descriptions Nike Romaleos: Volt color, Weightlifting shoes Chocolate Chips: Semi-sweet Powerbeats 2 Headphones: Bluetooth headphones (3) In main, prompt the user for a customer's name and today's date. Output the name and date. Create an object of type Shopping Cart (1 pt) Ex: Enter customer's name: John Doe Enter today's date: February 1, 2016 Customer name: John Doe Today's date: February 1, 2016 (4) Implement the PrintMenu() function in main.cpp to print the following menu of options to manipulate the shopping cart. (1 pt) Ex: MENU a - Add item to cart d - Remove item from cart C - Change item quantity i Output items' descriptions 0 - Output shopping cart q - Quit (5) Implement the ExecuteMenu() function in main.cpp that takes 2 parameters: a character representing the user's choice and the reference of a shopping cart. ExecuteMenuo performs the menu options described below, according to the user's choice. (1 pt) (6) In main(), call PrintMenu() and prompt for the user's choice of menu options. Each option is represented by a single character. If an invalid character is entered, continue to prompt for a valid choice. When a valid option is entered, execute the option by calling ExecuteMenu(). Then, print the menu and prompt for a new option. Continue until the user enters 'q'. Hint: Implement Quit before implementing other options. (1 pt) Ex: MENU a - Add item to cart d - Remove item from cart - Change item quantity i - Output items' descriptions Output shopping cart o q - Quit Choose an option: (7) Implement Output shopping cart menu option in ExecuteMenu(). (3 pts) Ex: OUTPUT SHOPPING CART John Doe's Shopping Cart - February 1, 2016 Number of Items: 8 Nike Romaleos 2 @ $189 = $378 Chocolate Chips 5 @ $3 = $15 Powerbeats 2 Headphones 1 @ $128 = $128 Total: $521 (8) Implement Output item's description menu option in ExecuteMenu0. (2 pts) Ex: OUTPUT ITEMS' DESCRIPTIONS John Doe's Shopping Cart February 1, 2016 Item Descriptions Nike Romaleos: Volt color, Weightlifting shoes Chocolate chips: Semi-sweet Powerbeats 2 Headphones: Bluetooth headphones (9) Implement Add item to cart menu option in Execute Menu0. (3 pts) Ex: ADD ITEM TO CART Enter the item name: Nike Romaleos Enter the item description: Volt color, Weightlifting shoes Enter the item price: 189 Enter the item quantity: 2 (10) Implement remove item menu option in ExecuteMenu(). (4 pts) Ex: REMOVE ITEM FROM CART Enter name of item to remove: Chocolate Chips (11) Implement Change item quantity menu option in ExecuteMenu. Hint: Make new Item To Purchase object and use Item ToPurchase modifiers before using Modifyltem() function. (5 pts) Ex: CHANGE ITEM QUANTITY Enter the item name: Nike Romaleos Enter the new quantity: 3
