Question

我做了一些修改并得到了正确的总数，但我似乎弄乱了所有的调整，我怎么能解决这个问题

#include <fstream> 
#include <iostream> 
#include <iomanip>

#include "WeeklyEmp.h" 

using namespace std;

int main()
{
ifstream inFile( "EMPLOYEE.DAT" );

if( !inFile )
{
    cout << "**Error opening file 'EMPLOYEE.DAT'" << endl;
}
else
{
    cout << "   Pay    Hours    Gross    Income    FICA      Net   Employee\n"
         << "  Rate   Worked      Pay      Tax      Tax      Pay   Name\n"
         << " =====   ======   ======   ======   ======   ======   ========\n";

    string fName, lName;
    double hours, rate, totGross = 0.0;
    int exempts;
    char status;
    double totHours = 0.0;
    double totIncome = 0.0;
    double totFica = 0.0; 
    double totNet = 0.0;

    cout << fixed << setprecision(2);

    while( inFile >> fName >> lName >> hours >> rate >> exempts >> status )
    {
        string name = lName + ", " + fName;
        WeeklyEmp anEmp( name, hours, rate, exempts, status ); 

        double net = anEmp.grossPay() - anEmp.incomeTax() - anEmp.FICATax();
        totGross += anEmp.grossPay();
        totIncome += anEmp.incomeTax();
        totFica += anEmp.FICATax();
        totHours += hours;
        totNet += net;

        cout << setfill( ' ' ) << setw(6) << rate << setfill( ' ' )
             << setw(9) << hours
             << setw(9) << anEmp.grossPay()
             << setw(9) << anEmp.incomeTax()
             << setw(9) << anEmp.FICATax()
             << setw(9) << net 
             << "   " 
             << anEmp.name()
             << endl;
        cout << "         ------   ------   ------   ------   ------"
             << setw(6) << "Totals"
             << setw(9) << totHours
             << setw(9) << totGross
             << setw(9) << totIncome
             << setw(9) << totHours
             << setw(9) << totNet; 

    }


}

cin.get();
return 0;
}

这就是输出看起来如何正确对齐，加上我得到的三倍“-----”和“总计”

这是应该的方式，总数就在那里。

Answer 1

您可以计算循环中的总数：

double sumHours = 0;

while( inFile >> fName >> lName >> hours >> rate >> exempts >> status )
{
    // ...

    sumHours += hours;

    // ...    
}

cout << sumHours;

获取列的总计
