Printf 函数通过引用传递

Question

我正在尝试用 C 编写一个简单的程序，它可以获取名称、小时费率和输入时间，并计算总工资、税金、净工资等，但我在制作一个打印结果的函数时遇到了困难。

我创建了两个循环：一个循环生成加班费、总工资、税收和净工资。打印出生成数据的另一个循环。第一个工作正常。它生成数据就好了，但是当我运行程序时，它只是忽略了第二个循环并完成了程序。

这只是一个没有返回值的简单 void 函数，但我被卡住了。我使用通过引用传递。如果您知道出了什么问题，请告诉我。

#include<stdio.h>
#include<stdlib.h>
#include <string.h>
#define size 5

char name[size][20];
float rate[size];
float hours[size];
int i = 0;

void input();
float getbasepay(float *rt, float *hr);
float getovtime(float *rt, float *hr);
float getgross(float *base, float *ovt);
float gettax(float *gross);
float getnetpay(float *gross, float *tax);
void printout(char name, float rate, float hours, float base, float  ovt, float gross, float tax, float net);


void input()
{   
    for (i = 0; i < size; i++)
    {
        puts("\ntype name: (type -1 to quit) \n");
        scanf_s("%19s", &name[i], 20);
        if (strcmp(name[i], "-1") == 0) { break; }
        puts("\ntype hourly rate: (type -1 to quit) \n");
        scanf_s("%f", &rate[i]);
        if (rate[i] == -1) { break; }
        puts("\ntype hours worked: (type -1 to quit) \n");
        scanf_s("%f", &hours[i]);
        if (hours[i] == -1) { break; }

float getbasepay(float *rt, float *hr)
{   float base;
    float baseo;
    float excessive = (*hr - 40);

    if (*hr <= 40) 
    {
        base = (*rt) * (*hr);
        return base;
    }
    if (*hr >= 40)
    {
        baseo = (*hr - excessive) * (*rt);
        return baseo;
    }

float getovtime(float *rt,float *hr)
{
    float time;
    float ovt;
    if (*hr >= 40) 
    {
        time = (*hr - 40);
        ovt = time * (*rt) *1.5;

        return ovt;
    }
    else

您的代码无法编译：

gcc -o main main.c

答案：

error: conflicting types for ‘printout’

确实，声明中的签名与您的签名不同 写在实现中（例如 char *name 而不是 char name 等）
