Question

Why is this file giving an error? I'm not sure what I'm looking for. It seems that all the syntax is correct. What am I looking for that is incorrect?

#include <iostream>
#include <fstream>
#include <string>

Explanation / Answer

//Hey you just started an else if clause without an if clause.This is the clause that you have started "if (mClientNumber == tClientNumber)".Thank you.If there are any doubts for you, comment below.Here's the the after modifying

#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main()

{

// Start
// Declarations
// InputFile masterFile;
ifstream masterFile;

// InputFile transactionFile;
ifstream transactionFile;

// OutputFile newMasterFile;
ofstream newMasterFile;

// num mClientNumber, mtotalClientCost, tClientNumber, titemClientCost
int mClientNumber, tClientNumber;

double mtotalClientCost, titemClientCost;

// string mClientfName, mClientlName
string mClientfName, mClientlName;

// output "Master File Updating Starting"
cout << "Master File Updating Starting" << endl;
  
// open masterFile "Master.rtf"
masterFile.open("Master.rtf");
  
// open transactionFile "Transaction.rtf"
transactionFile.open("Transaction.rtf");
  
// open newMasterFile "newMaster.rtf"
newMasterFile.open("newMaster.rtf");
  
// read mClientNumber, mClientfName, mClientlName, mtotalClientCost from masterFile
masterFile >> mClientNumber >> mClientfName >> mClientlName >> mtotalClientCost;
  
// read tClientNumber, titemClientCost from transactionFile
transactionFile >> tClientNumber >> titemClientCost;
  
  
// while ( transactionFile not EOF )

while((!(masterFile.eof())) && (mClientNumber < tClientNumber))

{

// endwhile
}

}
// endif
}

// endwhile
}
// while (masterFile not EOF)
