Answer:
See explaination
Explanation:
#include <fstream>
#include <iostream>
#include <iomanip>
using namespace std;
int main()
{
// Fill in the code to define payfile as an input file
ifstream payfile;
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
payfile.open("payroll.dat");
// Fill in code to write a conditional statement to check if payfile
// does not exist.
if(!payfile)
{
cout << "Error opening file. \n";
cout << "It may not exist where indicated" << endl;
return 1;
}
ofstream outfile("pay.out");
cout << "Payrate Hours Gross Pay Net Pay"
<< endl << endl;
outfile << "Payrate Hours Gross Pay Net Pay"
<< endl << endl;
// Fill in code to prime the read for the payfile file.
payfile >> hours;
// Fill in code to write a loop condition to run while payfile has more
// data to process.
while(!payfile.eof())
{
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;
outfile << payRate << setw(15) << hours << setw(12) << gross
<< setw(12) << net << endl;
payfile >> hours ;// Fill in the code to finish this with the appropriate
// variable to be input
}
payfile.close();
outfile.close();
return 0;
}
Answer:
You can open the version of your computer or device from the task manager to see the running programs and close the application
Explanation:
Right-click on the Windows Start menu and choose Task Manager (another way to open it is to press the keyboard shortcut Ctrl + Alt + Delete and select it from the options that appear).
NOTE: Click here if you don't know how to display Windows 8 Start.
You will see the main Administrator window (as in the image above). Displays a list of the programs that are currently running.
Find the application or process you want to close. Click on it with the RIGHT button and choose End task. In some cases a notice appears asking you to confirm it. Read what it says to know the consequences of forcing it. Confirm if you are determined to do so.
IMPORTANT:
There are viruses, adware or other spam programs that you may not be able to close even in this way. For these cases follow this link on how to clean viruses without entering Windows.
When you're done you can exit the Task Manager window. Click here to close background applications.
