Hi all. I am trying to read items from a text file whose name is input by the user and also output the receipt to a text file whose name is input by user.

I got stock for about 3 hours. Could you guys help? Thank You.

#include <iostream>
#include <iomanip>
#include <sstream>
#include <fstream>
#include <string>

using namespace std;

string formatDollar(double money);

int main () 
{
      double price_ticket;
      double base_cost;
      double total_cost;
      double tax_rate;
      double tax;
      string visiting_team;
	  // get four required data items from user
 
      cout << "Enter the name of the visiting team: ";
      getline(cin, visiting_team, '\n');
     
      cout << "Enter the number of tickets: ";
      cin >> num_tickets;
     
      cout << "Enter the price per ticket: ";
      cin >> price_ticket;
     
      cout << "Enter the sales tax rate (e.g., 7.0): ";


// Generate receipt for the ticket purchase in a separate file.
  ofstream myfile ("file.txt");
  if (myfile.is_open())
  {
    myfile << "  Nets vs. " << visiting_team << " at \"The Rock\"" << endl;
    myfile << "-----------------------------------------" << endl;
    myfile << "Number of tickets:" << setw(10) << num_tickets << endl;
    myfile << "Price per ticket:"  << setw(11) <<
            formatDollar(price_ticket) << endl;
    myfile << "Total ticket price:" << setw(9) <<
            formatDollar(base_cost) << endl;
    myfile << "Sales tax:" << setw(18) << formatDollar(tax) << endl;
    myfile << "-----------------------------------------" << endl;
    myfile << "Total amount due:" << setw(11) <<
            formatDollar(total_cost) << endl;

    myfile.close();
  }
  else cout << "Unable to open file";
  return 0;
}

{
           
   // Convert the given dollar amount into
   // a string with a leading "$"
   
   ostringstream convert;
   
   convert << setiosflags(ios::fixed);
   convert << setprecision(2);
   convert << "$" << money;
           
   return convert.str();
  
} // end formatDollar

What is contained in the input file?

Also, your function from 55 onwards doesn't have a return type, name, or parameters.
