Question

Consider the following incomplete C++ program:

#include <iostream>

int main()

{ ... }

A) Write a statement that includes the header files fstream, string, and iomanip in this program.

B) Write statements that declare inFile to be an ifstream variable and outFile to be an ofstream variable.

C) The program will read data from the file inData.txt and write output to the file outData.txt. Write statements to open both of these files, associate inFile with inData.txt, and associate outFile with outData.txt.

D) Suppose that the file inData.txt contains the following data: Giselle Robinson Accounting 5600 5 30 450 9 75 1.5 The first line contains a person's first name, last name, and the department the person works in. In the second line, the first number represents the monthly gross salary, the bonus (as a percent), and the taxes (as a percent). The third line contains the distance traveled and the traveling time. The fourth line contains the number of coffee cups sold and the cost of each coffee cup. Write statements so that after the program executes, the contents of the file outData.txt are shown as below. If necessary, declare additional variables. Your statements should be general enough so that if the contents of the input file changes and the program is run again (without editing and recompilin), it outputs the appropriate results.

Name : Giselle Robinson, Department : Accounting

Monthly Gross Salary: $5600.00, Monthly Bonus: 5.00%, Taxes: 30.00%

Paycheck: $4116.00

Distance Traveled: 450.00 miles, Traveling Time: 9.00 hours Average Speed: 50.00 miles per hour

Number of Coffee Cups Sold: 75, Cost: $1.50 per cup Sales Amount = $112.50

E) Write statements that close the input and output files.

F) Write C++ program that tests the statements in parts a through e.

This is what i have: (The build succeeds but doesn't present any results)

#include "stdafx.h"

#include <iostream>

#include <fstream>

#include <iomanip>

#include <string>

using namespace std;

int main()

{

   ifstream inFile;

   ofstream outFile;

   double monthlySalary, Bonus, taxes, distanceTraveled, travelingTime, coffeeCupsSold, Cost;

   double payCheck, averageSpeed, salesAmount;

   string firstName;

   string lastName;

   string department;

   inFile.open("inData.txt");

   outFile.open("outData.txt");

   outFile << fixed << showpoint;

   outFile << setprecision(2);

   cout << "Processing data" << endl;

   inFile >> firstName >> lastName >> department;

   outFile << "Employee Name: " << firstName

       << " " << lastName << "Department: " << department << endl;

   inFile >> monthlySalary >> Bonus >> taxes;

   outFile << "Monthly Gross Salary: $ " << monthlySalary << "Monthly Bonus: % " << Bonus << "Taxes: " << "%" << endl;

   payCheck = (monthlySalary * (Bonus / 100)) * (taxes / 100);

   outFile << "payCheck: $ " << payCheck << endl;

   inFile >> distanceTraveled >> travelingTime;

   averageSpeed = distanceTraveled / travelingTime;

   outFile << "Average Speed: " << averageSpeed << "miles per hour" << endl;

   inFile >> coffeeCupsSold >> Cost;

   salesAmount = coffeeCupsSold / Cost;

   outFile << "Sales Amount: $ " << salesAmount << endl;

   inFile.close();

   outFile.close();

   cin.get();

   return 0;

}

Explanation / Answer

//A) Includes the header files fstream, string, and iomanip
#include <iostream>

#include <fstream>

#include <iomanip>

#include <string>

using namespace std;

int main()

{
//B)Declare inFile and outFile
ifstream inFile;

ofstream outFile;

double monthlySalary, bonus, taxes, distanceTraveled, travelingTime, coffeeCupsSold, cost;

double payCheck, averageSpeed, salesAmount;

string firstName;

string lastName;

string department;

//C) Open inFile with inData.txt and outFile with outData.txt
inFile.open("inData.txt");

outFile.open("outData.txt");

outFile << fixed << showpoint;

outFile << setprecision(2);

cout << "Processing data" << endl;

//D) Reading data from inData,txt and copying content to outData.txt
inFile >> firstName >> lastName >> department;

outFile << "Name : " << firstName

<< " " << lastName << ", Department: " << department << endl;

inFile >> monthlySalary >> bonus >> taxes;

outFile << "Monthly Gross Salary: $" << monthlySalary << ", Monthly Bonus:" << bonus << "%, Taxes: " << taxes<<"%" << endl;

payCheck = (monthlySalary * (bonus / 100)) * (taxes / 100);

outFile << "PayCheck: $" << payCheck << endl;

inFile >> distanceTraveled >> travelingTime;

averageSpeed = distanceTraveled / travelingTime;

outFile <<"Distance Traveled:"<<distanceTraveled<<" miles, Traveling Time: "<< travelingTime <<" hours Average Speed: " << averageSpeed
<< " miles per hour" << endl;

inFile >> coffeeCupsSold >> cost;

salesAmount = coffeeCupsSold / cost;

outFile << "Number of Coffee Cups Sold: "<<coffeeCupsSold<<", Cost: $"<<cost<<" per cup Sales Amount = $" << salesAmount << endl;

// E). Close the input and output files
inFile.close();

outFile.close();

cin.get();

return 0;

}

It seems that you have not created proper inData.txt. Please create inData.txt file in following data in same folder where you have create "file.cpp"
