Question

You are given a C++ source file (Program6_Skeleton.cpp) with five missing/incomplete statements. Your task is to complete the code in this file such that it runs successfully. You are to replace all underlines with your code. You are also given two input files (oldmast.txt and trans.txt) and one output file (newmast.txt). The two input files contain data; the output file is empty. If your run is successful, the output file will contain the data shown in the sample output screen below.

oldmast.txt - 100 Ajax Orange 543.89 300 Sue Green 22.88 400 Clint White -6.32 500 Aias Blue 888.71 700 Tom Black 76.09 900 Marisal Pink 100.55

trans.txt - 100 134.17 300 627.19 400 1000.54 445 55.55 500 7.09 700 -99.66 900 100.00

The program must run once

Explanation / Answer

please rate - thanks

sample run

besides the fact that you posted a mess the program has bugs. I've highlighed my corrections for those.

// Program 6: Chapter 8 Exercise 8.7
// This is not a full programming exercise.
// Your job is to insert the missing five statements in the locations indicated below,
// get the program to produce the results shown in the assignment sheet.
#include <iostream>
#include <fstream>
#include <iomanip>

// exit function prototype
using namespace std;
void printOutput( ofstream&, int, string, string, double );
// prototype
int main()
{ int masterAccount;
// holds account from old master file
int transactionAccount;
// holds account from transactions file
double masterBalance;
// holds balance from old master file
double transactionBalance;
// holds balance from transactions file
string masterFirstName;
// first name from master file
string masterLastName;
// last name from master file
// file streams for input and output files (two IN/one OUT...complete the three statements below:
         ifstream inOldMaster;
          // delete underlines when inserting your code
          ifstream inTransaction;
          ofstream outNewMaster;
//files never opened
inTransaction.open("trans.txt");
inOldMaster.open("oldMast.txt");
outNewMaster.open("newMast.txt");
           // terminate application if old master file cannot be opened
           if ( !inOldMaster )
           { cerr << "Unable to open oldmast.txt ";
           exit( 1 ); }
           // end if
           // terminate application if transactions file cannot be opened
           if ( !inTransaction )
            { cerr << "Unable to open trans.txt "; exit( 1 ); }
            // end if
            // terminate application if new master file cannot be opened
            if ( !outNewMaster ) { cerr << "Unable to open newmast.txt "; exit( 1 ); }
// end if
// display account currently being processed.....insert one statement here
cout << "Processing... ";

// delete underline when inserting your code
// read from master file until end of transactions file reached

//transaction information never initioalized before being used

inTransaction >> transactionAccount >> transactionBalance;
while ( !inTransaction.eof() )
{ inOldMaster >> masterAccount >> masterFirstName >> masterLastName >> masterBalance;
   // display accounts from master file until
   // number of new account is reached..........insert two less than conditions that need to be met here

//only 1 needed
   while ( masterAccount < transactionAccount )
   // delete underlines when inserting your code here
   { printOutput( outNewMaster, masterAccount, masterFirstName, masterLastName, masterBalance );
   inOldMaster >> masterAccount >> masterFirstName >> masterLastName >> masterBalance;
   }
    // end while
     // tell user if account from transactions file does not match
     // account from master file

//the way you have it, first time through transactionAccount not initialized

    if ( masterAccount > transactionAccount )
     { cout << "Unmatched transaction record for account " << transactionAccount << ' ';
      // get account and balance from transactions file
      inTransaction >> transactionAccount >> transactionBalance; }
      // end if
       // if matching account found, update balance and output account info
       if ( masterAccount == transactionAccount )
       { masterBalance += transactionBalance;
       printOutput( outNewMaster, masterAccount, masterFirstName, masterLastName, masterBalance ); }
       // end if
       // get next account and balance from transactions file
