How do you read this code into a file and display it into cout and stop the program once you read "END" for the name of the produce?

The code:

#include<iostream>
#include<string.h>
#include<fstream>
using namespace std;

int main()
{
    string filename;
    cout<<"Enter the name of the file to store the information"<<endl;
    getline(cin,filename);
    ofstream fileptr(filename);
    if(!fileptr.is_open())
    {
        cout<<"Couldn't open a file"<<endl;
    }
    string product,temp;
    double wholesaleprice, totalprice, markup, retailprice, totalretailprice;
    char option;
    int quantity;
    do
    {
        cout<<"Enter the product name"<<endl;
        getline(cin, product);
        cout<<"Enter the Wholesale Price"<<endl;
        cin>>wholesaleprice;
        cout<<"Enter the quantity"<<endl;
        cin>>quantity;
        totalprice = wholesaleprice*quantity;
        cout<<"Enter the markup percentage"<<endl;
        cin>>markup;
        retailprice = wholesaleprice + ( (markup/100)*wholesaleprice );
        totalretailprice = retailprice * quantity;
        fileptr<<product<<endl;
        fileptr<<wholesaleprice<<" "<<quantity<<" "<<retailprice<<" "<<(totalretailprice-totalprice)<<endl;
        cout<<"Do you want to process any more records (y/n)?"<<endl;
        cin>>option;
        getline(cin,temp);
    }while(option=='y');
    fileptr.close();
}
