C 在 main 中调用打印函数

我是 C 语言的新手,我正在编写一段代码来创建一个包含员工信息数组的结构。正如您在我的代码中看到的那样,有员工(实际上有 4 个,但为了空间我将其缩减为 1 个),并且每个员工都有相应的信息。 (仅供引用,为了节省空间,我省略了一些东西,比如声明 struct workerT)。

我创建了另一个函数 (prntWorker),它应该打印所有员工及其信息,但是当我在 main() 中调用它时,我不知道如何使用边界。无论我使用什么边界,CodeBlocks 都会返回参数太少。很抱歉,我知道这是一个新手问题,但我将不胜感激任何帮助!

目标是“给定一个包含 siz 元素的 workerT 结构数组,打印在数组元素列表 [indx] 中找到的所有员工信息

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define MAX_ROSTER 10 //roster of employees

typedef struct workerT_struct {
char name[81]; //employee name
char title[81]; //employee title
int empID; //unique ID for employee
int empStatus;
int year100_salary; //before-tax salary, in cents
int year100_401k; //annual contribution to retirement, in cents
double taxRate; //fraction used to determine payroll taxes
int month100_paycheck; //monthly paycheck, in cents
} workerT;

void initWorkerArray(workerT list[], int siz);
void prntWorker(workerT list[], int siz, int indx);


int main()
{
workerT roster[MAX_ROSTER];
prntWorker(roster, MAX_ROSTER, 0); //FIXME
return 0;
}

void initWorkerArray(workerT list[], int siz) {
int i = 0;
for (i = 0; i < 4; ++i) {
strcpy(list[0].name, "Buggy, Orson");
strcpy(list[0].title, "Director/President");
list[0].empID = 1;
list[0].empStatus = 1;
list[0].year100_salary = 12015000;
list[0].year100_401k = 950000;
list[0].taxRate = 0.45;

strcpy(list[1].name, "Czechs, Imelda");
strcpy(list[1].title, "Chief Financial Officer");
list[1].empID = 2;
list[1].empStatus = 1;
list[1].year100_salary = 8020000;
list[1].year100_401k = 960000;
list[1].taxRate = 0.39;

strcpy(list[2].name, "Hold, Levon");
strcpy(list[2].title, "Customer Service");
list[2].empID = 6;
list[2].empStatus = -1;
list[2].year100_salary = 8575000;
list[2].year100_401k = 1133000;
list[2].taxRate = 0.39;

strcpy(list[3].name, "Andropov, Picov");
strcpy(list[3].title, "Shipping Coordinator");
list[3].empID = 7;
list[3].empStatus = 1;
list[3].year100_salary = 4450000;
list[3].year100_401k = 375000;
list[3].taxRate = 0.31;
}

for (i = 4; i < siz; ++i) {
strcpy(list[i].name, "none");
strcpy(list[i].title, "none");
list[i].empID = -1;
list[i].empStatus = -1;
list[i].year100_salary = 0;
list[i].year100_401k = 0;
list[i].taxRate = 0.0;
}
return;
}

void prntWorker(workerT list[], int siz, int indx) {
int i = 0;
for (i = 0; i < siz; ++i) {
printf("%s ", list[indx].name);
printf("%s ", list[indx].title);
printf("%d ", list[indx].empID);
printf("%d ", list[indx].empStatus);
printf("%d ", list[indx].year100_salary);
printf("%d ", list[indx].year100_401k);
printf("%lf ", list[indx].taxRate);
printf("%d ", list[indx].month100_paycheck);
}
return;
}

最佳答案

这里有几个问题:

永远不要调用 initWorkerArray 来初始化数组:

int main()
{
workerT roster[MAX_ROSTER];
initWorkerArray(roster, MAX_ROSTER); // add this call
prntWorker(roster, MAX_ROSTER, 0);
return 0;
}

initWorkerArray 内部,不需要第一个 for 循环,因为您正在更新数组中的特定索引。

您永远不会在第二个 for 循环或初始字段中初始化 month100_paycheck,因此该字段包含垃圾:

list[0].month100_paycheck = 0;
...
list[1].month100_paycheck = 0;
...
list[2].month100_paycheck = 0;
...
list[3].month100_paycheck = 0;
...
for (i = 4; i < siz; ++i) {
....
list[i].month100_paycheck = 0;
}

然后在 prntWorker 中,您没有使用循环索引 i 来遍历列表。您正在使用参数 indx 而不是您真正需要的参数:

void prntWorker(workerT list[], int siz) {
int i = 0;
for (i = 0; i < siz; ++i) {
printf("%s ", list[i].name);
printf("%s ", list[i].title);
printf("%d ", list[i].empID);
printf("%d ", list[i].empStatus);
printf("%d ", list[i].year100_salary);
printf("%d ", list[i].year100_401k);
printf("%lf ", list[i].taxRate);
printf("%d ", list[i].month100_paycheck);
printf("\n"); // put a newline at the end for nicer formatting
}
return;
}

更改此函数后,还要更改main中的调用:

    prntWorker(roster, MAX_ROSTER);

进行这些更改后,您应该得到以下输出:

Buggy, Orson Director/President 1 1 12015000 950000 0.450000 0
Czechs, Imelda Chief Financial Officer 2 1 8020000 960000 0.390000 0
Hold, Levon Customer Service 6 -1 8575000 1133000 0.390000 0
Andropov, Picov Shipping Coordinator 7 1 4450000 375000 0.310000 0
none none -1 -1 0 0 0.000000 0
none none -1 -1 0 0 0.000000 0
none none -1 -1 0 0 0.000000 0
none none -1 -1 0 0 0.000000 0
none none -1 -1 0 0 0.000000 0
none none -1 -1 0 0 0.000000 0
