The Curl Up and Dye Beauty Salon maintains a master file that contains a record for each of its clients. Fields in the master file include the client's ID number, first name, last name, and total amount spent this year. Every week a transaction file is produced. It contains a customer's ID number, the service received (for example, Manicure), and the price paid. Each file is sorted in ID number order. Design the logic for the program that matches the master and transaction file records and updates the total paid for each client by adding the current week's price paid to the cumulative total. Not all clients purchase services each week. The output is the updated master file and an error report that lists any transaction records for which no master record exists.

Explanation / Answer

I have writtem a c++ code for the same based on the input fields given in he pseudo code.

Working c++ code:

#include <cstdlib>
#include <iostream>
#include <fstream>
#include <string>
using namespace std;

int main()
{
ifstream masterFile;
ifstream transactionFile;
ofstream newMasterfile;
int mClientNumber;
string mClientfName;
string mClientlName;
double mtotalClientCost;
int tClientNumber;
int tServiceRequested;
   double titemClientCost;
  

cout << "Master File Updating Starting..." << endl;

masterFile.open("Master.txt");
transactionFile.open("Transaction.txt");
newMasterfile.open("newMaster.txt");
  
  
while(!masterFile.eof())
{
   masterFile >> mClientNumber;
masterFile >> mClientfName;
masterFile >> mClientlName;
masterFile >> mtotalClientCost;
  
transactionFile >> tClientNumber;
transactionFile >> tServiceRequested;
    transactionFile >> titemClientCost;
  
       if (mClientNumber >= tClientNumber)
{
       mtotalClientCost = mtotalClientCost + titemClientCost;
                  newMasterfile << mClientNumber << " ";
            newMasterfile << mClientfName << " ";
            newMasterfile << mClientlName << " ";
            newMasterfile << mtotalClientCost << endl;
       }   
  
  
          

else
{
cout << "Error Client ID: " << tClientNumber << " Not in Master File.";
}
}
cout << "Master File Updating Complete " << endl;

masterFile.close();
transactionFile.close();
newMasterfile.close();
return 0;
}
