n this final exam programming assignment, you will define class Item and Cart, then implement object-oriented programming in C++ program. (40 pts) (5 pts) Complete the Item class declaration in Item.h file with the following data members and member functions: • Data member o Name of the item o Cost of the item Member function o Default constructor with no parameter o Constructor with two parameters o The accessor functions to return name o The accessor function to return cost #ifndef ITEM_H #define ITEM_H #include using std::string; class Item public: write your code write your code write your code write your code private: write your code write your code }; #endif <> (5 pts) Complete the Cart class declaration in Cart.h file with the following data members and member functions: • Data member o Cart name o Count of Item objects purchased An array of Item objects with maximum capacity of 100 Member functions o Constructor with the parameter of cart name o Purchase function that takes an Item object as parameter and returns a boolean value (True: the Item object is added in the array successfully. False: the Item array is full) o PrintTotal function that calculates and prints the total cost of the items purchased on the screen and returns nothing. #include "Item.h" #include using namespace std; class Cart { public: write your code write your code write your code private: string _name; int _count; Item _arr[100]; }; <> (10 pts) Complete the function definitions in Item.cpp file. <4> (10 pts) Complete the function definitions in Cart.cpp file. <5> (10 pts) Complete the tester program in Source.cpp file to implement object-oriented programming. • Create a Cart object. • Define a sentinel-value controlled while loop to ask user to enter the purchased item name and cost repeatedly. • Create Item object using the input item name and cost. • Call the cart object's Purchase function to add the input Item object in the item object array. • After user enter all purchased item objects, call the cart object's PrintTotal function to calculate and display the total cost (ignore the sales tax) on the screen. #include #include #include "Cart.h" #include "Item.h" using namespace std; int main() { char choice - string itemName = double cost = 0.0; bool added; // create a Cart object ----- write your code cout << "Would you like to puchase an item from the store (y/n)? "; cin >> choice; choice = tolower(choice); while (----- write your code ---) { cin.ignore(); cout << "What is the name of the item that you like to purchase? "; getline(cin, itemName); cout << "What is the cost of the item? "; cin >> cost; // create an Item object ----- write your code // call cart object's Purchase function to add item in the cart array write your code ----- ----- if (----- write your code -----) { cout << "Error: You have exceeded the limit of allowed purchases." << endl; break; } 11 ask user to input next purchased item name and cost write your code ----- } // call cart object's function to calculate and display total cost ----- write your code ----- return 0; Here is the sample input and output ---- CS Microsoft Visual Studio Debug Console Would you like to puchase an item from the store (y/n)? y What is the name of the item that you like to purchase? milk What is the cost of the item? 2 Would you like to puchase another item from the store (y/n)? y What is the name of the item that you like to purchase? bread What is the cost of the item? 1 Would you like to puchase another item from the store (y/n)? y What is the name of the item that you like to purchase? egg What is the cost of the item? 3.5 Would you like to puchase another item from the store (y/n)? n The total cost of the purchase is: 6.50
