cant read last char from a file

**aze** · 04-25-2004

hey guys!

i make a code to open and read a text file.

Code:

		 while( fgets(tmpstr, 127, fp) ){

it runs ok. but when the file dont have a \n char being the last char in the file, my code cant read the last file's char.

file1---------------------
text 123
just junk text
more text

end file 1---------------

file2---------------------
text 123
just junk text
more text
end file 1---------------

if i try to read file2 i cant read the last char (t) on the file. But it not happens with file1 (once the t char isnt the last one)

I already tried using feof() but the same occurs.
I also tried to set

Code:

fp--;

but i cant make it work...

This should work. If you still have problems with yours, post your code here

Code:

#include <stdio.h>

int main(void)
{
  FILE *fp;
  char buf[BUFSIZ];
  
  if ((fp = fopen("junk1.c", "r")) != NULL)
  {
    while (fgets(buf, sizeof(buf), fp))
    {
      printf ("%s", buf);
    }
    fclose(fp);
  }
  
  return(0);
}

Erm, Hammer, don't you need to declare BUFSIZ?

No

Well, yes, but it's done for you in stdio.h.

Don't you know by now that's in stdio.h ?

I think he was trying to make me panic and think I'd made a mistake.

In all honesty, I didn't know that it was declared in stdio.h. *puts on flame retardant suit*
