Given a ListItem class, complete main() using the built-in list type to create a linked list called shoppingList. The program should read items from input (ending with -1), adding each item to shoppingList, and output each item in shoppingList using the PrintNodeData() function.

This is in C++.

Given a ListItem class, complete main() using the built-in list type to create a linked list called shoppingList. The program should read items from input (ending with -1), adding each item to shoppingList, and output each item in shoppingList using the PrintNodeData() function.

EX INPUT

milk

bread

eggs

waffles

cereal

-1

Ex OUTPUT

milk

bread

eggs

waffles

cereal

main.cpp

#include "ListItem.h"
#include <string>
#include <list>
#include <iostream>

using namespace std;

int main (int argc, char* argv[]) {
// TODO: Declare a list called shoppingList of type ListItem

string item;

// TODO: Read inputs (items) and add them to the shoppingList list
// Read inputs until a -1 is input

// TODO: Print the shoppingList list using the PrintNodeData() function

return 0;
}
