Answer to Question #200228 in C++ for fgh

Question

1. Assume that the data file has hours, pay Rate, state Tax, and fedTax on one line for 

each employee. state Tax and fedTax are given as decimals (5% would be .05). Complete this program by filling in the code (places in bold). 

Answer 1

#include <fstream>
#include <iostream>
#include <iomanip>
using namespace std;

int main()
{
// Fill in the code to define payfile as an input file

float gross;

float net;

float hours;

float payRate;
float stateTax;
float fedTax;
cout << fixed << setprecision(2) << showpoint;
// Fill in the code to open payfile and attach it to the physical file
// named payroll.dat

// Fill in code to write a conditional statement to check if payfile
// does not exist.
{
cout << "Error opening file. \n";
cout << "It may not exist where indicated" << endl;
return 1;
}
cout << "Payrate Hours Gross Pay Net Pay"
<< endl << endl;
// Fill in code to prime the read for the payfile file.

// Fill in code to write a loop condition to run while payfile has more
// data to process.
{
payfile >> payRate >> stateTax >> fedTax;
gross = payRate * hours;
net = gross - (gross * stateTax) - (gross * fedTax);
cout << payRate << setw(15) << hours << setw(12) << gross
<< setw(12) << net << endl;
payfile >> // Fill in the code to finish this with the appropriate
// variable to be input

payfile.close();
return 0;
}
}
