can someone edit this code where it will output to a file

#include <iostream>
#include <fstream> //For file operations
#include <string.h> //For string comparisions
using namespace std;
struct StockNode{ //Creating of linked list node structure
   char itemname[20];
   char itemnumber[5];
   char quantity[3];
   char price[6];
   char safestock[3];
   struct StockNode *link;
};

class InventoryStock //Class for operations and members
{
   StockNode *head;
   public:
       InventoryStock() //Constructor default
       {
           head=NULL;
       }
       void addStockNode(StockNode *nn) //Add node method
       {
           StockNode *temp=NULL;
           if(head==NULL || strcmp(head->itemname,nn->itemname)>=0)   // Adding first node whether null or head node smaller than nn
           {
