I can't figure out how to get the modify to work correctly. I have done most of the coding but can't figure out where I need to change what or what I am missing. As shown below the ModifyItem needs to be able to modify description, price, and or quantity.

main.cpp

#include #include "ShoppingCart.h" #include "ItemToPurchase.h"

using namespace std;

void PrintMenu(ShoppingCart shoppingCart) { while(1) { cout > option; while (option != 'a' && option != 'd' && option != 'c' && option != 'i' && option != 'o' && option != 'q' ) { cin >> option; } switch (option) { case 'o': { cout > itemPrice; cout > itemQuantity; ItemToPurchase item1 = ItemToPurchase(itemName, itemDescription, itemPrice, itemQuantity); shoppingCart.AddItem(item1); break; } case 'd': { string itemName; cout > newQuantity; shoppingCart.ModifyItem(itemName); break; } case 'q': { exit(4); } } } } int main() { string customerName; string currentDate; cout

ItemToPurchase.cpp

#include using namespace std; #include "ItemToPurchase.h"

ItemToPurchase::ItemToPurchase() { ItemName = "none"; ItemDescription = "none"; ItemPrice = 0.0; ItemQuantity = 0; }

ItemToPurchase::ItemToPurchase(string itemName, string itemDescription, double itemPrice , int itemQuantity) { ItemName = itemName; ItemDescription = itemDescription; ItemPrice = itemPrice; ItemQuantity = itemQuantity; }

void ItemToPurchase::SetName(string itemName) { ItemName = itemName; } void ItemToPurchase::SetPrice(double itemPrice) { ItemPrice = itemPrice; } void ItemToPurchase::SetQuantity(int itemQuantity) { ItemQuantity = itemQuantity; } void ItemToPurchase::SetDescription(string itemDescription) { ItemDescription = itemDescription; }

string ItemToPurchase::GetName() { return ItemName; } double ItemToPurchase::GetPrice() { return ItemPrice; } int ItemToPurchase::GetQuantity() { return ItemQuantity; } string ItemToPurchase::GetDescription() { return ItemDescription; }

void ItemToPurchase::PrintItemCost() { cout

void ItemToPurchase::PrintItemDescription() { cout
