Reading lines separately from a file.

Hi all!

During my OS assignment, I'm having a little problem regarding filing. The problem is that I'm to read each line in a separate array and after that perform further operations. I've initially read the entire file in a char array and after that I intend to split it up accordingly. The file is in the following format:

P1 0
12 2 21 2 12 32 18
P2 9
13 17 3 21 45 67 21

(and so on)

I've written the following code:

Code:

(Variables definitions and all)

f=fopen ("umer.txt","r");
if (!f)
      printf ("Could not open the file.\n");
while (fgets (s,'\n',f)!=NULL)
{
      if (s[i] == 'P')
      {
            processes++;
      }
      printf ("%s", s);
}
printf ("processes are: %d\n", processes);
printf ("\n");
fclose(f);

while (s[i]!='\n')
{
      printf ("char is: %c\n", s[i]);
      i++;
      printf ("-%d-", i);
}

But when I output the supposedly initial charaters from the array s[i] (which contains the entire file supposedly), it outputs 4,5,7,6. (It should output the first line of the file, i.e P1 (a tab) 0)

What should I do? Any help would be highly appreciated.

Thanks.

Where is i in the midst of this? You can't just use the same value for i the whole time.

Code:

fgets (s,'\n',f)

you should really start reading the reference guide instead of dropping random parts of the code together in hope that it will somehow work...

magic is not applicable to programming... (if you are interested in the results of course)

It's actually:

Code:

fgets (s,1000,f)
