我需要帮助指出此代码中的错误，该错误旨在导入文本文件并将数据存储在不同的变量中

Question

这是我的代码：

#include <stdio.h>
#include <stdlib.h>

#define MAX_APPOINTMENTS 50

int main(){

     int appointmentCount = importAppointments("appointmentData.txt", appoints, MAX_APPOINTMENTS);
     printf("Imported %d appointment records...\n\n", appointmentCount);

     return 0;

}

int importAppointments(char *filename, struct Appointment appoints[], int max){
    
    FILE* file = fopen(filename, "r");
    
    int i=0;
    char ch;
    if (file != NULL)
    {

        while (i < max && fscanf(file, "%d,%d,%d,%d,%d,%d%c",
              &appoints[i].patientNumber, &appoints[i].date.year, &appoints[i].date.month,
              &appoints[i].date.day, &appoints[i].time.hour, &appoints[i].time.min, &ch) == 7)
        {

            if(ch != '\n')
            {
                while(fgetc(file) != '\n');
            }
        
            i++;
        }
        
        
        fclose(file);
        file = NULL;
    }else{

        printf("Error opening file: %s\n", filename);
        return 0;
    }
    
    
    return i;
}

我一直出错；代码无法读取文件；我已经完成了一些故障排除步骤，但无法找到问题所在。 我检查了文件是否在同一个目录中，检查了是否有错字等

Answer 1

1. main()

   ：您需要文件底部的 importAppointments()

   or move

   main()` 原型。

2. main()

   ：

   appoints

   未申报。

3. struct Appointment

   没有申报

4. 至于特定的错误消息，它表明您的文件

   appointmentData.txt

   在当前工作目录中不可读。您可以使用

   getcwd()

   找出那是什么。还要确保查看文件的所有者/组/权限。

#include <stdio.h>
#include <stdlib.h>

struct Appointment {
    int patientNumber;
    struct {
        int year;
        int month;
        int day;
    } date;
    struct {
        int hour;
        int min;
    } time;
};

#define MAX_APPOINTMENTS 50

int importAppointments(char *filename, struct Appointment appoints[], int max){
    FILE *file = fopen(filename, "r");
    if(!file) {
        printf("Error opening file: %s\n", filename);
        return 0;
    }
    int i=0;
    char ch;
    while (i < max && fscanf(file, "%d,%d,%d,%d,%d,%d%c",
            &appoints[i].patientNumber, &appoints[i].date.year, &appoints[i].date.month,
            &appoints[i].date.day, &appoints[i].time.hour, &appoints[i].time.min, &ch) == 7) {
        if(ch != '\n')
            while(fgetc(file) != '\n');
        i++;
    }
    fclose(file);
    return i;
}

void printAppointments(size_t n, struct Appointment appoints[n]) {
    for(size_t i = 0; i < n; i++)
        printf("patient number: %d\n"
            "date (YYYY/MM/DD): %d/%d/%d\n"
            "time: %d:%d\n"
            "%s",
            appoints[i].patientNumber,
            appoints[i].date.year,
            appoints[i].date.month,
            appoints[i].date.day,
            appoints[i].time.hour,
            appoints[i].time.min,
            i + 1 < n ? "-\n" : "\n"
        );

}


int main(void) {
    struct Appointment appoints[MAX_APPOINTMENTS];
    int appointmentCount = importAppointments("appointmentData.txt", appoints, MAX_APPOINTMENTS);
    printf("Imported %d appointment records...\n\n", appointmentCount);
    printAppointments(appointmentCount, appoints);
}

和示例输出：
