My function is not reading data from the input file properly (C)

I am having trouble with the ReadPersonData function. I need to read in data from a and store the data in structure arrays.

Data looks like this: Name, Country, City, Street, Hobby count, Hobbies

I am having trouble reading in the hobbies. It will read in the hobbies until the hobby count goes from 3 to 2, then it stops reading in data, probably because in the cycle
for(i = 0; i < personList[persons.hobbyCount; i++) , i is now bigger than a persons hobby count. I want it to keep on reading data, but I just can’t figure it out.
Since English is not my first language I don’t know how to search for solutions on this particular topic and ChatGPT is not helping so now here I am. How do I fix my problem?

} address;

typedef struct

} person;

int ReadPersonData(person personList[] , int limit, char *fName);

  int personCount = ReadPersonData(personList, MAX_PERSONS, ARG_FILE_NAME);


  return 0;

int ReadPersonData(person personList[] , int limit, char *fName)
{

  int persons = 0;
  int i;

  FILE *fPerson = fopen(fName, "r");
  if(fPerson == NULL)
  {
    fprintf(stderr, "Error opening input file %s", fName);
    perror(" ");
    return persons;
  }

  while(fscanf(fPerson, "%s %s %s %s %d", personList[persons].name,
                                          personList[persons].residence.country,
                                          personList[persons].residence.city,
                                          personList[persons].residence.street,
                                         &personList[persons].hobbyCount) == 5)

  {

    if(personList[persons].hobbyCount < MIN_HOBBIES ||
    personList[persons].hobbyCount > MAX_HOBBIES)
      {
        printf("ERROR! Invalid hobby count for %s, exiting now!\n",
        personList[persons].name);
        exit(1);
      }

   for(i = 0; i < personList[persons].hobbyCount; i++)
   {
     fscanf(fPerson, "%s", personList[persons].hobbies[i]);
   }

    persons++;

   if(persons > limit)
   {
     fprintf(stderr, "ERROR! Input file is too long! ALlowed "
                        "limit is %d entries. Reading of the "
                        "file has stopped, continuing within "
                        "a partial dataset\n", limit);
     break;
   }
  }

fclose(fPerson);

return persons;

}

I tried to change the cycle parameters to no avail.

>Solution :

This line has 2 extra data after 2 hobbies:

Therefore, after reading the hobbies (Cooking Fishing), your program will behave as if the data left is added before the next line and the next line is :

Then the format specifier %d won’t accept the non-integer input Tijuana and reading stops.

One way for fixing this is skipping the extra data after hobbies like this:

   for(i = 0; i < personList[persons].hobbyCount; i++)
   {
     fscanf(fPerson, "%s", personList[persons].hobbies[i]);
   }

   // add this to skip until the end of line
   int c;
   while ((c = getchar()) != '\n' && c != EOF);

    persons++;

Note that this way doesn’t support cases where data after the hobby count is less than the hobby count or lines has other issues. To support these cases, you should use other ways like reading whole lines via fgets and parsing the lines (using strtok, for example).
