Help displaying line numbers of a text document

Sorry for being such a noob before and asking for help without trying prior to posting. In any case I've figured out most of my program, I'm just having trouble getting my program to display the line numbers before to the lines of text. This is what I have so far:

Code:

---


#include <stdio.h>
#define LINE_LENGTH 80

int main()
{
    FILE *fp = fopen("test.txt", "r");
    char line[LINE_LENGTH];
    while (fgets(line, LINE_LENGTH, fp) != NULL)
    {
          printf( "%s", line);
    }
    getchar();
}

---

Code:

---

  int count = 0;
  while ( fgets(line, sizeof line, fp) != NULL )
  {
      printf( "%2d : %s", ++count, line);
  }

---

Thanks a bunch, can you explain to me what %2d is?

It means that the integer will be at least two characters in size, and will be padded with spaces if it's less than two chars. That is, printf("%2d", 3) prints "<space>3". You can make printf pad with zeros instead of spaces with printf("%02d", 3) which prints "03".

I see thank you very much
