Set and Get elements from objects in C++

From the suggested answer Why does std::getline() skip input after a formatted extraction? getline() is not working for the follwing code but cin>>ws . Can anyone explain why?

Problem: In this I have created a class Restaurant and created its object pointer *my_restaurant. I'm trying to set data in object from user input and show it in output. But its not working, properly. What should i do? Output is shown in attached image. Thanks in advance

#include<bits/stdc++.h>
using namespace std;
    
class Restaurant
{
public:
    int food_item_codes[12];
    string food_item_names[12];
    int food_item_price[12];
    int total_tax;
};



int main()
{
    Restaurant *my_restaurant = new Restaurant;
    int n;
    cin>>n;
    for(int i = 0; i<n; i++)
    {
        cin>>my_restaurant->food_item_codes[i];
        getline(cin,(my_restaurant->food_item_names[i]));
        cin>>my_restaurant->food_item_price[i];
    }

    cout<<"Make Bill"<<endl;
    cout<<"Item code \t\t\t\t"<<"Item Name \t\t\t\t"<<"item price"<<endl;
    for(int i = 0; i<n; i++)
    {
        cout<<my_restaurant->food_item_codes[i]<<"\t\t\t\t";
        cout<<my_restaurant->food_item_names[i]<<"\t\t\t\t";
        cout<<my_restaurant->food_item_price[i]<<endl;
    }




    return 0;

}

Output
