为什么我的netpay 显示没有答案？

Question

我正在编写工资单检查代码。一个函数询问用户工作时间和小时工资。另一个函数接受小时数和费率作为参数并计算并返回总工资。然后将 Grosspay 发送到一个函数，该函数将计算并返回 payrolltax(.22)。然后调用一个函数，该函数将接受 Grosspay 和 tax 作为参数并返回 netpay。最后将所有数据发送到将显示所有值（总小时数、小时工资率、总工资、税金和净工资）的函数。我的 netpay 显示我 0，而 tax 显示错误答案。谁能告诉我哪里出错了？

/* Payroll Check */
#include <stdio.h>

float askhoursworked();
float askhourlyrate();
float calculategrosspay(float hours,float rate);
float calculatepayrolltax(float grosspay);
float calculatenetpay(float grosspay,float tax);
float displayallvalues(float ,float ,float,float ,float );

int main()
{
      float hours;
      float rate;
      float grosspay;
      float tax;
      float netpay;
      float values;

      hours=askhoursworked();
      rate= askhourlyrate();

      tax=  calculatepayrolltax( grosspay);
      netpay= calculatenetpay( grosspay,tax);
      grosspay=calculategrosspay( hours,  rate);

      values= displayallvalues( hours, rate, tax, grosspay, netpay);

      return 0;
}


 float askhoursworked()
 { 
       float hours;
       printf("\n Please enter hours worked \t");

    return rate; 
 }

    grosspay=hours*rate;

    return grosspay;

    printf("\n Your netpay is %.2f",netpay);
}

在 C 语言中，使用单遍编译器。这意味着在这里，顺序最重要。 你终于在计算总工资了。并且您正在使用它来计算 netpay 和税收。

这是正确的方法..

 hours = askhoursworked ();
 rate = askhourlyrate ();
 grosspay = calculategrosspay (hours, rate);
 tax = calculatepayrolltax (grosspay);
 netpay = calculatenetpay (grosspay, tax);

编辑 您还以错误的方式打印了输出。

  printf ("\n Your total hours are %.2f", hours);
  printf ("\n Your hourly rate  %.2f", rate);
  printf ("\n Your grosspay is %.2f", grosspay);
  printf ("\n Your taxes are %.2f", tax);
  printf ("\n Your netpay is %.2f", netpay);
