Online shopping cart (continued) (C++)

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
  • SetDescription() mutator & GetDescription() accessor (2 pts)
  • PrintItemCost() - Outputs the item name followed by the quantity, price, and subtotal
  • PrintItemDescription() - Outputs the item name and description
  • Private data members
  • string itemDescription - Initialized in default constructor to "none"

Ex. of PrintItemCost() output:

Bottled Water 10 @ $1 = $10


Ex. of PrintItemDescription() output:

Bottled Water: Deer Park, 12 oz.


(2) Create three new files:

  • ShoppingCart.h - Class declaration
  • ShoppingCart.cpp - Class definition
  • main.cpp - main() function (Note: main()'s functionality differs from the warm up)

Build the ShoppingCart 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
  • string customerName - Initialized in default constructor to "none"
  • string currentDate - Initialized in default constructor to "January 1, 2016"
  • vector < ItemToPurchase > cartItems
  • Public member functions
  • GetCustomerName() accessor (1 pt)
  • GetDate() accessor (1 pt)
  • AddItem()
    • Adds an item to cartItems vector. Has parameter ItemToPurchase. Does not return anything.
  • RemoveItem()
    • 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 cart. Nothing removed.
  • ModifyItem()
    • Modifies an item's description, price, and/or quantity. Has parameter ItemToPurchase. 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.
  • GetNumItemsInCart() (2 pts)
    • Returns quantity of all items in cart. Has no parameters.
  • GetCostOfCart() (2 pts)
    • Determines and returns the total cost of items in cart. Has no parameters.
  • PrintTotal()
    • Outputs total of objects in cart.
    • If cart is empty, output this message: SHOPPING CART IS EMPTY
  • PrintDescriptions()
    • Outputs each item's description.


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 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 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
d - Remove item from cart
c - Change item quantity
i - Output items' descriptions
o - Output shopping cart
q - Quit

Choose an option:


(5) Implement 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 2 Headphones 1 @ $128 = $128

Total: $521


(6) Implement 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 2 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 remove item 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 and use ItemToPurchase modifiers before using ModifyItem() function. (5 pts)

Ex:

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

#main.cpp

#include <iostream>
#include "ItemToPurchase.h"
#include <cstdlib>

using namespace std;

int main() {
   ItemToPurchase item1, item2;
   string name;
   double price;
   int q;
   cout << "Item 1" << endl;
   cout << "Enter the item name:"<< endl;
   getline(cin, name);
   cout << "Enter the item price:"<<endl;
   cin >> price;
   cout << "Enter the item quantity:"<<endl;
   cin >> q;
   item1.SetName(name);
   item1.SetPrice(price);
   item1.SetQuantity(q);

   cout << "\nItem 2" << endl;
   cout << "Enter the item name:"<<endl;
   cin.ignore();
   getline(cin, name);
   cout << "Enter the item price:"<<endl;
   cin >> price;
   cout << "Enter the item quantity:"<<endl;
   cin >> q;
   item2.SetName(name);
   item2.SetPrice(price);
   item2.SetQuantity(q);

   cout << "\nTOTAL COST" << endl;
   cout << item1.GetName() << " " << item1.GetQuantity() << " @ $" << item1.GetPrice() << " = $" << item1.GetPrice() * item1.GetQuantity() << endl;
   cout << item2.GetName() << " " << item2.GetQuantity() << " @ $" << item2.GetPrice() << " = $" << item2.GetPrice() * item2.GetQuantity() << endl;

   cout << "\nTotal: $" << (item1.GetPrice() * item1.GetQuantity()) + (item2.GetPrice() * item2.GetQuantity())<<endl;
   return 0;
}

ItemToPurchase.h

#ifndef ItemToPurchase_H
#define ItemToPurchase_H

#include <string>

using namespace std;

class ItemToPurchase {
private:
   string itemName;
   double itemPrice;
   int itemQuantity;
public:
   ItemToPurchase();
   void SetName(string name);
   void SetPrice(double price);
   void SetQuantity(int quantity);
   string GetName();
   double GetPrice();
   int GetQuantity();
};
#endif

ItemToPurchase.cpp

#include "ItemToPurchase.h"

ItemToPurchase::ItemToPurchase() {
   itemName = "none";
   itemPrice = 0.0;
   itemQuantity = 0;
}

void ItemToPurchase::SetName(string name) {
   itemName = name;
}

void ItemToPurchase::SetPrice(double price) {
   itemPrice = price;
}

void ItemToPurchase::SetQuantity(int quantity) {
   itemQuantity = quantity;
}

string ItemToPurchase::GetName() {
   return itemName;
}

double ItemToPurchase::GetPrice() {
   return itemPrice;
}

int ItemToPurchase::GetQuantity() {
   return itemQuantity;
}

this is the previous program.
