如何将 txt 文件存储为两个字符串数组？

Question

现在我被困在如何从文本文件中获取字符串并根据这些单词创建两个单独的数组。文件中的字符串示例如下：

BQN 阿瓜迪亚，波多黎各

格式：

<3 letter code><2 white spaces><a string up to 100 characters>

有一个 100 strings 列表，我正在尝试创建一个数组来仅存储 3 个字母代码，另一个 array 来存储机场。

代码：

    #include <stdio.h>
    #include <string.h>

    #define MAX_LINE_LENGTH 1000

    int main()
    {
      FILE *airports;
      airports = fopen("airports.txt", "r");
      FILE *routes;
      routes = fopen("routes.txt", "r");
      FILE *flights;
      flights = fopen("flights.txt", "r");

      char line[MAX_LINE_LENGTH];
      char air[100][3];
      char airp[100][100];


      if (airports == NULL)
        {
           printf("Could not open database files\n");

        }
      else
        {
          int i = 0;
          while(fgets(line, MAX_LINE_LENGTH, airports) != NULL)
            {
              sscanf(line, "%s" , air[i]);
              strcpy(airp[i], line+5);
               i++;


            }
          printf("%s" "%s", air, airp);

这个项目还有很多，所以代码不完整。

我已经包含了 printf 只是为了查看数组是否有效。到目前为止，它只在一行中打印了所有 3 个字母代码，后跟第一个机场。

我的描述有点混乱，但我们将不胜感激！

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


#define MAX_LINE_LENGTH 100
int  getline(char ** lineptr, size_t * linelen, FILE * stream);


int main()
{
  FILE *airports;
  airports = fopen("airports.txt", "r");
  FILE *routes;
  routes = fopen("routes.txt", "r");
  FILE *flights;
  flights = fopen("flights.txt", "r");

  char line[MAX_LINE_LENGTH];

  char air[5][100];
  char airp[100][100];
    int i = 0,lines=0;

  if (airports == NULL)
    {
       printf("Could not open database files\n");
        exit(1);
    }
  else
    {


        while (fgets( line,  MAX_LINE_LENGTH, airports)  )
        {
            for(int j=0 ; j<MAX_LINE_LENGTH;j++){
                if(line[j]=='\n'){
                    line[j]=0;
                    break;
                }
            }

            sscanf(line, "%3s" , air[lines]); //first 3 chars
            strcpy(airp[lines],&line[4]);   // the remaining chars starting from 4

            lines++;

            if(lines==100) // up to 100 line allowed
                break;

        }
      fclose(airports);
    }

    // printing the arrays
    for(i=0;i<lines;i++){
        printf("%d - '%s' - '%s'\n",i+1,air[i],airp[i]);
    }


}
