        averagehoursWork= totalhoursWork/totalEmployees;
        totalEmployees++;

            }       
    averagehoursWork= totalhoursWork/totalEmployees;
     for (int x = 1; x < 44; x = x + 1) 
         cout <<"*";
         cout << endl;



    cout <<"Total Employees Entered=" << totalEmployees << endl;
    cout <<" Total Hours Worked="<< fixed << setprecision(2) << totalhoursWork << endl;
    cout <<" Average Hours Worked="<< fixed << setprecision(2) << averagehoursWork << endl;
    cout <<" Total Net Pay="<<fixed << setprecision(2) << totalnetPay << endl;
    cout <<" TotalwithHoldings=" << fixed << setprecision(2)<< totalwithHoldings << endl;

     for (int x = 1; x < 44; x = x + 1) 
         cout <<"*";
         cout << endl;


system("pause");
return 0;
      }

每小时费率必须大于$ 7.25且小于$ 100.00。工作小时数必须大于0且小于120.如果用户输入无效数据显示和相应的错误消息并要求用户重新输入。 我应该对这部分使用什么声明？我应该把它放在哪里？

Answer 1

你可以使用Cin和Cout进行输入和输出，只需使用do while循环

 int employeeNum = 0;

            do
            {
                Console.WriteLine("enter Employee /Number 9999 to STOP");
                employeeNum = int.Parse(Console.ReadLine());

                if (employeeNum == 9999)
                    break;

                Console.WriteLine("enter hourly rate ");
                double hourRate = Double.Parse(Console.ReadLine());




            } while (employeeNum != 9999);

Answer 2

您可以这样做：

cout << "Enter hourly rate:";
cin >> hourlyRate;
while (hourlyRate <= 7.25 || hourlyRate >= 100) {
    cout << endl << "Reenter hourly rate (must be in (7.25 - 100))";
    cin >> hourlyRate;
}

但是stackoverflow不适合别人做你的作业。

如何在另一个循环中输入循环？
