Problem with fgets function

I have a file foo.txt with 2 lines. I want to retrieve each of them in variables for use in the main code.

Code:

---

void reading_file()
{
char *name = "foo.txt";
char line [BUFSIZ];

FILE *file = fopen (name, "r");
if (file != NULL)
{
while (fgets (line, sizeof line, file) != NULL)
{
printf("%s", line);
}
fclose (file);
}
else
{
perror ("Impossible to open the file.");
}
}

If you want to use your variables in the main code you have to create storage space for your lines with a malloc.

Then (if you do not know the number of variables lines refer to the main code) you must do a dynamic sort a linked list that contains:

- A pointer to the malloc that contains your credit line
- A pointer to the next cell containing the next cell

For code I had think there's not too far already for a moment, I tried to find it in the evening if necessary.

My first line is set to 4 bytes. The second is an integer between 1 and 1000. I want to code if it is not too much a constraint. I used this piece of code using the function scanf that works and meets my needs but I do not know if this is optimal.

Code:

---

void reading_file()
{
  char *name = "foo.txt"; 
  char value1[4];
  char value2[BUFSIZ];
  FILE *file;
 
  if ((file = fopen (name, "r")) == NULL)
  perror ("Impossible to open the file.");
  else
  {
      while ( fscanf ( file, "%s %s", value1, value2 ) == 2)
      printf("%s\n%s\n", value1, value2);
  fclose (file);
  }
}

The problem is when I try to do a comparison test between value1 and an integer, I have this error message:

Attention: Comparison between a pointer and an integer

This is normal: value1 is a pointer to an array of 4 characters.
