Invoice Class)

Create a class called

Invoice that a hardware store might use to

represent an invoice for an item sold at the

store. An Invoice should include four data

membersa part number (type string), a

part description (type string), a quantity of

the item being purchased (type int) and a

price per item (type int).

Your class should have a constructor that

initializes the four data members. Provide a

set and a get function for each data member.

In addition, provide a member function named getInvoiceAmount that calculates the invoice

amount (i.e., multiplies the quantity by the price per item), then returns the amount as an int

value. If the quantity is not positive, it should be set to 0. If the price per item is not positive, it

should be set to 0. Write a test program that demonstrates class Invoices capabilities.

The following is a sample of what your output may look like:

nclude using namespace std; ShopItem class definition ***/ class ShopItem { public void SetNameAndPrice(string itemName, int itemPrice); void Print() const ShopItem() 1/ Default constructor private string name; I/ Ex: "Bag of salad" int price; // Price in cents. Ex: 199 3: ShopItem::ShopItemOt 7Default constructor name = "NoName.. ; price = -1; // Default name // Default price return; void ShopItem::SetNameAndPrice(string itemName, int itemPrice) [ nameitemName; price itemPrice; Name: NoName, Price: -1 Name: Soap, Price: 385 return; void ShopItem: Print) const cout
