sscanf problem, program modified but with slight problem still, please help!

As i had stated on a previous thread, i found out that sscanf is better when parsing string literals, my program compiles but the output is not what i expect.

My input file is as follows: CityStats.txt with the following data

San Ignacio;Cayo;4000;5

and my output comes out as :

San Ignacio
Cayo
808464436
50921525

i got no idea how i get those final results. Can anyone help, i tried making it as simple as possible. the last two output should be 4000 and finally 5, but there is some wierd problems. advice, suggestions anyone, here is the code i have:

Code:

---

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

int main(void)
{
   
    struct stats {
      char town [32];
      char district [32];
      int pop;
      int quality;
      };
     
   
    struct stats stat;
    char line[50]; /* space to read a line into */
    int result;
   
   
    char filename[] = "CityStats.txt"; /* the name of a file to open */
    FILE *file = fopen(filename, "r"); /* try to open the file */
    if ( file )
    {
     
      while ( fgets(line, sizeof line, file) ) /* read each line */
      {
        result=sscanf(line, "%[^;];%[^;];%[^;];%[^;]",stat.town,stat.district,&stat.pop,&stat.quality);
      }
   
      fclose(file);
  }
  printf("sscanf successfully converted %d items!\n\n",result);
 

  printf("%s\n%s\n%d\n%d", stat.town, stat.district, stat.pop,stat.quality);
 

   
 return 0;
}

Try this sscanf line instead:

Code:

---

result=sscanf(line, "%32[ a-zA-Z];%32[ a-zA-Z];%d;%d",stat.town,stat.district,&stat.pop,&stat.quality);

---

If there is a newline in CityStats.txt, result will be 0 because sscanf read the next (empty) line.

ps. anything involving square brackets is about characters and you can't put that into an int

Hey i got that to work, thank you very much. I got a question, imagine id have another line on the text file such as:

Halie Villie;Hampshire;2000;3
Hell,Heaven,800,4

how would i go about doin the same thing as what i did on the top. Now would if statements be needed to look up new line characters. Any ideas!

Thanks by the way it did help

I would use strtok for this. That way, you can set the delimiter to ";," which will cover both cases.

Code:

---

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

int main(void)
{
   
    struct stats {
      char town [32];
      char district [32];
      int pop;
      int quality;
      };
     
   
    struct stats stat;
    char line[50]; /* space to read a line into */
   
    char filename[] = "CityStats.txt", *tok;
    FILE *file = fopen(filename, "r"); /* try to open the file */
    if ( file )
    {
     
      while ( fgets(line, 50, file) ) /* read each line */
      {
        tok=strtok(line,";,");
        strcpy(stat.town,tok);
        tok=strtok(NULL,";,");
        strcpy(stat.district,tok);
        tok=strtok(NULL,";,");
        stat.pop=atoi(tok);
        tok=strtok(NULL,";,");
        stat.quality=atoi(tok);
        printf("%s\n%s\n%d\n%d\n", stat.town, stat.district, stat.pop,stat.quality);
      }
   
      fclose(file);
  }
 return 0;
}

There is no "result" measurement in this one.

I'd appreciate it, thank u in advance and for all the help u have given me!
