Question

我在使用这段代码时遇到了很多麻烦。作业是：

您要编写一个程序来处理员工及其薪酬。对于每个员工，该计划将读取员工的姓名和每小时工资率。它还应该读取每天工作5小时的工作小时数并计算他或她的总工作小时数。您必须使用循环读取小时数。该计划应输出员工姓名，工资总额，扣缴总额和净工资。“ 预扣税由州税，联邦税和FICA组成。就本计划而言，州税是总薪酬的1.25％。 FICA将占总薪酬的7.65％。如果总薪酬低于500美元，则联邦税将为总薪酬的15％，否则为25％您不知道有多少员工，但会有员工姓名的哨兵。哨兵是“完成”

但是代码编译输出总是很大的指数。谢谢你的任何建议。

Answer 1

您似乎没有初始化“付款”的值。

我错过了你初始化的地方吗？

也许你的意思是：

pay = calcPay(rate, sum);

等

另外：如果你在输出（...）中计算“with”，“gross”和“net”，你可能不应该将它们作为未初始化的变量传递。你是说他们出来（例如参考）还是他们在之前被初始化了？

Answer 2

在代码变量pay中，gross，pay和pay未初始化。由于上面的代码，它将是这样的：

net

输出给出指数，因为在代码中明确放置了int main() { string name, done; int counter; float rate, sum, gross, with, pay, net; instructions(name, rate, sum); pay = calcPay(rate, sum); gross = calcGross(pay); with = calcAmount(gross); net = calcNet(gross, with); output(name, rate, sum, with, gross, net, pay); return 0; }。由于人类可读性，我在下面的代码中省略了精度：

<<setprecision(2)

Answer 3

您忘记在main函数中初始化变量。只需像这样修改你的程序，它就可以运行。

int main()
{
    string name, done;
    int counter;
    float rate, sum, gross, with, pay, net;
    instructions(name, rate, sum);
    pay=calcPay(rate, sum);
    output(name, rate, sum, with, gross, net, pay);
    return 0;
}

void output(string name, float rate, float sum, float& with, float& gross, float& net, float& pay)
{
    gross = calcGross(pay);
    with = calcAmount(gross);
    net = calcNet(gross, with);
    cout<<"Payroll"<<'\n';
    cout<<"======================================="<<'\n';
    cout<<"Employee name:                        "<<name<<'\n';
    cout<<"Gross pay:                            $ "<<gross<<'\n';
    cout<<"Total Withholding:                    $ "<<with<<'\n';
    cout<<"Net pay:                              $ "<<net<<'\n';
}

for-loop错误地输出指数
