有人可以帮我用我的C代码吗

Question

Hello so i am creating a program that reads from a file and outputs each category of the things in the text in sorted for example i want it to output like this :

Company name: air france Date of creation: 06281957 Flight number: AT6801 Incoming city: london Arrival city: paris Amount of fuel liters left: 380 Plane category: B777

this is the input :

air qatar06281957AT680londonmadrid380B777 turkish airlines05201933TK1298istanbulmadrid250A380 lufthansa01061953LH29frankfurtmadrid75B747 air canada06281957AT7245ammanmadrid120A320 turkish airlines05201933TK1266dohamadrid522A320 air france10071933AF123parismadrid105B777 -1

I have been struggling with a lot of things but I finally managed to separate every category to a different array, however , when I tried to do it for 2D array I always get garbage can someone point out what the mistake I did ?

we couldn't read in the input file and write it in a 2D array so the concept that i have used in this code i search in the array until i find something that would help me separate the word from the others such as 06281957 in the input i used isdigit to identify which index has it then i copy the previous characters into a new array this trick seemed to work for a 1d array however when i tried to scan it to 2d it stopped working and only random chars seemed to appeari wanted to print the whole 2d array of each category but i failed to do so, for the variables i used them as checkpoints for the next check to put the things i want in a new array. For minimizing the code i cant seem to find another solution to do so i know that my code is very big but if someone has a better idea it would be awesome.

Answer 1

One thing that will simplify your code is using scansets . It will make it much easier to extract and separate digits from non-digits, lower from upper case. Fixed width specifiers is also a concept you should read into. To see how many characters where extracted, use %n described in previous link. Examples:

  /* ... */
  inp=fopen("input.txt","r");
  /* your code... */
  for(i=0;!feof(inp);i++)
  {
    fscanf(inp,"%c",&ultimate_array[i]);
  }
  s=strlen(ultimate_array);
  for(i=0;i<s;i++)
  {
    printf("%c",ultimate_array[i]);
  }

  /* ...can be replaced by something similar to this (untested) */
  fscanf(inp, "%599s%n", ultimate_array, &s); /* read up to 599 characters, put number of read characters in s */
  ultimate_array[s]=0; /* set null terminator */
  char a[10]; sprintf(a, "%%%ds", s); /* create print format, e.g. "%123s" */
  printf(a, ultimate_array) /* print 's' number of characters */

Make sure to take it slow as the lines can be hard to read initially. As you become more familiar with it I'm sure you will find scanf does "exactly what is needed" using no loops or conditions at all.

Don't use feof . Instead check the return value from scanf . If you try extract a single "something" from file using scanf and it returns 0 (zero arguments were filled), you are done reading the file.

Making 2D arrays is almost always wrong. Group your variables in structures:

typedef struct flights_t {
  char plane[100];
  char date[100];
  /* ... */
} flights[6]; unsigned int nrOfFlights = 0;

int c[16];
int t[7];

Make symbolic constants instead of litering the code with copies of 20 , 100 and 6 all over for improved readability and maintainance. You will also recieve much better help from forums such as SO.

Your posted code is sadly beyond saving without proper description of what each code section is supposed to do. Hopefully this "answer" will get you going making better code.
