[英]Question about void functions
I know my code is correct except one thing. 我知道我的代码是正确的,只有一件事。 After I enter the first weekly salary, everything is displayed.
输入第一周薪后,将显示所有内容。 But when I go to enter another weekly salary, the FWI, FICA & NET PAY does not show.
但是当我输入另一个每周工资时,FWI,FIA和NET PAY不会显示。
Here's my code: 这是我的代码:
#include <iostream>
#include <iomanip>
using namespace std;
//function prototypes
void getSalary(double &salary);
void calcFedTaxes(double salary, double FWT_RATE, double FICA_RATE, double &fwt, double &fica);
void calcNetPay(double salary, double fwt, double fica, double &netPay);
void displayInfo(double fwt, double fica, double netPay);
int main()
{
//declare constants and variables
const double .2;
const double FICA_RATE = .08;
double salary = 0;
double fwt = 0;
double fica = 0;
double netPay = 0;
//get salary
getSalary(salary);
//calculate the federal taxes
calcFedTaxes(salary, FWT_RATE, FICA_RATE, fwt, fica);
//calculate net pay
calcNetPay(salary, fwt, fica, netPay);
//display , gross, taxes, and net
displayInfo(fwt, fica, netPay);
while (salary != 0)
{
cout << "Weekly salary: ";
cin >> salary;
} //end while
return 0;
} //end of main function
//*****function definitions*****
void getSalary(double &salary)
{
cout << "Weekly salary: ";
cin >> salary;
} //end of getSalary
void calcFedTaxes(double salary, double FWT_RATE, double FICA_RATE, double &fwt, double &fica)
{
fwt = salary * FWT_RATE;
fica = salary * FICA_RATE;
} //end of calcFedTaxes
void calcNetPay(double salary, double fwt, double fica, double &netPay)
{
netPay = salary - fwt - fica;
} //end of calcNetPay
void displayInfo(double fwt, double fica ,double netPay)
{
cout << "FWT: " << fwt << endl;
cout << "FICA: " << fica << endl;
cout << "Net: " << netPay << endl;
} //end of displayInfo
It's because your call to displayInfo()
is outside of the while loop. 这是因为您对
displayInfo()
调用不在 while循环中。 So it will only be called that one time. 所以它只会被调用一次。 You need to move it into the loop and call it with the appropriate parameters there.
您需要将其移入循环并在其中使用适当的参数进行调用。
