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. If the input is: milk bread eggs waffles cereal -1 the output is: milk bread eggs waffles cereal #include "ListItem.h" #include #include #include 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; } #ifndef LISTITEMH #define LISTITEMH #include using namespace std; class ListItem {    public:       ListItem();       ListItem(string itemInit);       // Print this node       void PrintNodeData();    private:       string item; }; #endif #include "ListItem.h" #include ListItem::ListItem() {    item = ""; } ListItem::ListItem(string itemInit) {    item = itemInit; } // Print this node void ListItem::PrintNodeData() {    cout << item << endl; }
