クラスオブジェクトを使用する配列の合計

Question

5人の従業員全員のグロスペイの合計を取得するにはどうすればよいですか？私はオブジェクトの作成を含むすべてを試しましたが、うまくいかないようです。また、すべてのデータをEmpDataという1つの配列に格納する必要がありますので、変更することはできません。私は援助が必要です。これは私が作成したコードで、これまで実行され正常に動作しています。

#include<iostream> 

using namespace std; 
class Employee { 
private: 
    double hourswrk; 
    double payrate; 
    double grosspay; 
    int empno; 
    char empname[20]; 
    double netpay; 
    double tax; 
    double overt; 
    double overtime; 
    double taxdeduct; 

public: 
    void getdetails(); 
    void calculatepay(); 
    void showdetails(); 
}; 
void Employee::getdetails() 
{ 
    cout << "\nEnter employee name:\n"; 
    cin >> empname; 
    cout << "\nEnter employee number:\n"; 
    cin >> empno; 
    cout << "Enter hours worked:"; 
    cin >> hourswrk; 
    cout << "Enter rate of pay"; 
    cin >> payrate; 
} 
void Employee::calculatepay() 
{ 
    tax = 0.25; 
    overt = 1.5; 
    if(hourswrk >= 60) 
    { 
     grosspay = 0; 
     netpay = 0; 
     taxdeduct = 0; 

     cout << "You have exceeded the amount of hours!"; 
    } 
    else if(hourswrk <= 40) 
    { 
     grosspay = hourswrk * payrate; 
    } 
    else if(hourswrk > 40 && hourswrk < 60) 
    { 
     overtime = hourswrk - 40; 
     grosspay = overt * payrate*overtime + hourswrk * payrate; 
    } 
    taxdeduct = tax * grosspay; 
    netpay = grosspay - taxdeduct; 
} 

void Employee::showdetails() 
{ 
    cout << "Employee Payslip\n"; 
    cout << "Name: " << empname; 
    cout << "Employee number:" << empno; 
    cout << "Basic Salary" << payrate; 
    cout << "Hours work" << hourswrk; 
    cout << "Grosspay" << grosspay; 
    cout << "Tax: " << taxdeduct; 
    cout << "Net Salary" << netpay; 
    cout << endl; 
} 

int main() 
{ 
    Employee EmpData[5]; 
    int i; 
    double hourswrk; 
    double payrate; 
    double grosspay; 
    int empno; 
    char empname[20]; 
    double netpay; 
    double tax = 0.25; 
    double taxdeduct; 
    double overt = 1.5; 
    double overtime; 

    for(int i = 0; i < 5; i++) 
    { 
     EmpData[i].getdetails(); 
     EmpData[i].calculatepay(); 
     EmpData[i].showdetails(); 
    } 
    system("pause"); 
    return 0; 
}

は、私はちょうどあなたがエラーがありますgrosspaygrosspayがtotgrosspay

#include<iostream> 
    long totgrosspay=0; 
    using namespace std; 
    class Employee { 
    private: 
     long grosspay=0; 
     double hourswrk; 
     double payrate; 
     int empno; 
     char empname[20]; 
     double netpay; 
     double tax; 
     double overt; 
     double overtime; 
     double taxdeduct; 

    public: 
     void getdetails(); 
     void calculatepay(); 
     void showdetails(); 

    }; 
    void Employee::getdetails() 
    { 
     cout << "\nEnter employee name:\n"; 
     cin >> empname; 
     cout << "\nEnter employee number:\n"; 
     cin >> empno; 
     cout << "Enter hours worked:"; 
     cin >> hourswrk; 
     cout << "Enter rate of pay"; 
     cin >> payrate; 

    } 
    void Employee::calculatepay() 
    { 
     tax = 0.25; 
     overt = 1.5; 
     if(hourswrk >= 60) 
     { 
      grosspay = 0; 
      netpay = 0; 
      taxdeduct = 0; 

      cout << "You have exceeded the amount of hours!"; 
     } 
     else if(hourswrk <= 40) 
     { 
      grosspay = hourswrk * payrate; 
     } 
     else if(hourswrk > 40 && hourswrk < 60) 
     { 
      overtime = hourswrk - 40; 
      grosspay = overt * payrate*overtime + hourswrk * payrate; 
     } 
     taxdeduct = tax * grosspay; 
     netpay = grosspay - taxdeduct; 
     totgrosspay= totgrosspay+grosspay; 
    } 

    void Employee::showdetails() 
    { 
     cout << "Employee Payslip\n"; 
     cout << "Name: " << empname; 
     cout << "Employee number:" << empno; 
     cout << "Basic Salary" << payrate; 
     cout << "Hours work" << hourswrk; 
     cout << "Grosspay" << grosspay; 
     cout << "Tax: " << taxdeduct; 
     cout << "Net Salary" << netpay; 
     cout << endl; 
    } 

    int main() 
    { 
     Employee EmpData[5]; 
     int i; 

     for(int i = 0; i < 5; i++) 
     { 
      EmpData[i].getdetails(); 
      EmpData[i].calculatepay(); 
      EmpData[i].showdetails(); 

     } 
     cout<<totgrosspay;// it prints gross pay value 
     system("pause"); 

     return 0; 

}
