There are 9 member functions and a Product struct in order to complete the Products class. Products p; p.read_files(qr, price); struct Product \{ // You need to fill here with necessary member variables // You can add a constructor and simple functions as well \}; class Products \{ private: vector item_list; vector shop_list; public: Products(); Products(const Products \& p); vector get_item_list() const; vector get_shop_list() const; // you are going to implement these member functions void read_files(ifstream \& qr, ifstream \& price); // it reads gr and price files and stores them into item_list bool find(string qr_code); // given ar code it searches that inside item_list bool findInShoplist(string qr_code); // given ar code it searches that inside shop_list void add_item(string qr, int amount); // adds an item to the shop_list void edit_item(string qr, int amount); // edits an item in teh shop_list void remove_item(string qr); // removes an item from the shop_list void printCurrentReceipt(); // prints the current receipt void printCurrentReceiptAscending(); // prints the current receipt in ascending order void printCurrentReceiptDescending(); // prints the current receipt in descending order
