我在这段代码上遇到了很多麻烦。任务是：
你要写一个程序来处理员工和他们的工资。对于每个员工，该程序将读取一名员工的姓名和时薪。它还应读取5天内每天工作的小时数，并计算他或她的总工作小时数。你必须用循环读小时数。该程序应输出员工的姓名、工资总额、预扣总金额和净工资。"
预扣税由州税、联邦税和FICA组成。就本计划而言，州税将为总工资的1.25%。FICA将占总薪酬的7.65%。如果总工资低于500美元，联邦税将为总工资的15%，否则为25%
您不知道有多少员工，但会有一个员工姓名的哨兵。哨兵"完成"
代码编译，但是输出总是大指数。谢谢你的建议。

样品运行：
Enter the name of the employee: Alice
Enter the hourly pay rate: 7.75
Enter the number of hours worked for Day 1: 5
Enter the number of hours worked for Day 2: 6
Enter the number of hours worked for Day 3: 5
Enter the number of hours worked for Day 4: 4
Enter the number of hours worked for Day 5: 5
Payroll
=======================================
Employee name: Alice
Gross pay: $ -1.9e+38
Total Withholding: $ -4.8e+37
Net pay: $ -1.4e+38
您似乎没有初始化"pay"的值。
我是否缺少您初始化它的位置？
也许你的意思是：
pay = calcPay(rate, sum);
等等。
此外：如果您正在计算输出中的"with"、"gross"one_answers"net"（…），则可能不应该将它们作为未初始化的变量传入。你的意思是让它们出来（例如引用），还是它们之前被初始化了？
在代码中，变量pay、gross、pay和net未初始化。由于您上面的代码，它将是这样的：
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;
}
输出给出了指数，因为在代码中明确放置了<<setprecision(2)。由于人类的可读性，我只是在下面的代码中省略了精度：
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';
}
您忘记初始化main函数中的变量。只要像这样修改你的程序，它就可以运行了。
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';
}
