Please write in C. This is not C++.

This program extends the earlier "Online shopping cart" program. (Consider first saving your earlier program).

(1) Extend the ItemToPurchase struct to contain a new data member. (2 pt)

char itemDescription[ ] - set to "none" in MakeItemBlank()

Implement the following related functions for the ItemToPurchase struct.

PrintItemDescription()

Has an ItemToPurchase parameter.

Ex. of PrintItemDescription() output:

Bottled Water: Deer Park, 12 oz. 

(2) Create three new files:

ShoppingCart.h - struct definition and related function declarations

ShoppingCart.c - related function definitions

main.c - main() function (Note: main()'s functionality differs from the warm up)

Build the ShoppingCart struct with the following data members and related functions. Note: Some can be function stubs (empty functions) initially, to be completed in later steps.

Data members (3 pts)

char customerName [ ]

char currentDate [ ]

ItemToPurchase cartItems [ ] - has a maximum of 10 slots (can hold up to 10 items of any quantity)

int cartSize - the number of filled slots in array (number of items in cart of any quantity)

Related functionsAddItem()

Adds an item to cartItems array. Has parameters ItemToPurchase and ShoppingCart. Returns ShoppingCart object.

RemoveItem()

Removes item from cartItems array (does not just set quantity to 0; removed item will not take up a slot in array). Has a char and a ShoppingCart parameter. Returns ShoppingCart object.

If item name cannot be found, output this message: Item not found in cart. Nothing removed.

ModifyItem()

Modifies an item's description, price, and/or quantity. Has parameters ItemToPurchase and ShoppingCart. Returns ShoppingCart object.

GetNumItemsInCart() (2 pts)

Returns quantity of all items in cart. Has a ShoppingCart parameter.

GetCostOfCart() (2 pts)

Determines and returns the total cost of items in cart. Has a ShoppingCart parameter.

PrintTotal()

Outputs total of objects in cart. Has a ShoppingCart parameter.

If cart is empty, output this message: SHOPPING CART IS EMPTY

PrintDescriptions()

Outputs each item's description. Has a ShoppingCart parameter.

Ex. of PrintTotal() 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 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 ShoppingCart. (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. PrintMenu() has a ShoppingCart parameter, and outputs a menu of options to manipulate the shopping cart. Each option is represented by a single character. Build and output the menu within the function.

If the an invalid character is entered, continue to prompt for a valid choice. Hint: Implement Quit before implementing other options. Call PrintMenu() in the main() function. Continue to execute the menu until the user enters q to Quit. (3 pts) Ex:

MENU a - Add item to cart r - Remove item from cart c - Change item quantity i - Output items' descriptions o - Output shopping cart q - Quit Choose an option: 

(5) Implement the "Output shopping cart" menu option. (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 Headphones 1 @ $128 = $128 Total: $521 

(6) Implement the "Output item's description" menu option. (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 Headphones: Bluetooth headphones 

(7) Implement "Add item to cart" menu option. (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 

(8) Implement the "Remove item from cart" menu option. (4 pts) Ex:

REMOVE ITEM FROM CART Enter name of item to remove: Chocolate Chips 

(9) Implement "Change item quantity" menu option. Hint: Make new ItemToPurchase object before using ModifyItem() function. (5 pts) Ex:

CHANGE ITEM QUANTITY Enter the item name: Nike Romaleos Enter the new quantity: 3
