I'm not sure how to finish the code to match the sample output in the picture. Do I need to do the same thing I did in the 'hammer' output?

(please try to match how I coded my work so that I could easily understand. Thank you)

#include

using namespace std;

class Invoice //create class called Invoice { private: //Only for Invoice class string inClassNumber; string inClassDescription; int inClassQuantity; int inClassPrice;

public: //Included in main Invoice(string number, string description, int quantity, int price) { inClassNumber = number; inClassDescription = description; inClassQuantity = quantity; inClassPrice = price; }

//set function void set_inClassNumber(string num) /umber { inClassNumber = num; } void set_inClassDescription(string desc)//description { inClassDescription = desc; } void set_inClassQuantity(int qty) //quantity { if(qty

//get function string get_inClassNumber() /umber { return inClassNumber; } string get_inClassDescription() //description { return inClassDescription; } int get_inClassQuantity() //quantity { return inClassQuantity; } int get_inClassPrice() //price { return inClassPrice; }

//find invoice amount int get_invoiceAmount() { int amount; amount = inClassQuantity*inClassPrice;

return amount; }

};

int main() //main { Invoice invoice("12345", "Hammer", 100, 5); //invoice hammer example cout

return 0; }

C++ Creating Classes (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 members-a 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 O. Write a test program that demonstrates class Invoice's capabilities. The following is a sample of what your output may look like: Heidis-MacBook-Pro-3:classChallenge heidis ./a.out Part number: 12345 Part description: Hammer Quantity: 100 Price per item: $ 5 Invoice amount: $500 quantity cannot be negative. quantity set to 0. Invoice data members modified Part number: 123456 Part description: Saw Quantity: 0 Price per item: $10 Invoice amount: $0 Heidis - MacBook-Pro-3:class Challenge heidis
