Answer to Question #315859 in C++ for amna

Question

You are required to implement a shopping cart module for an online shopping mall. From the available

items a user will select the item to purchase and add this into his shopping cart. Before the checkout

customer can remove any item from the cart at any time.

A single item in the cart contains the following details:

class Item

{

private:

int itemID;

string itemName;

double price;

double purchasedQuantity;

double totalPrice;

public:

//constructors and getter setters

};

For the implementation of the required module you have to meet the following requirements:

1- Customer can add any item to the cart in desired quantity.

Remember if customer added the same item in the cart again, your implementation will not add

this as a new item it will check if the item already exists than it will just add the new quantity in

the previous and update other data.

Answer 1

class Item
{
public:
	Item(string itemName, int price, int purchasedQuantity, int itemId);
	void totalPrice()
	{
		cout << "Total price: " << price * purchasedQuantity << endl;
	}
	
private:
	int itemId;
	string itemName;
	double price;
	double purchasedQuantity;
	double totalPrice;
};
