Can someone help me fix my code! Thank you!

I'm reading from the data file and it prints out with like so:

Code:

---

**************************************

*                                            *

---

My code is printed below....I can't have the spaces and i thought that NULL was supposed to eliminate the blankline. What am I doing wrong? If I use printf after fgets i get garbage and sometimes errors that i cannot convert char to char.

Code:

---

if(fgets(line, MAXLINE, inputFILE)!=NULL)
    puts(line);
 if(fgets(line, MAXLINE, inputFILE)!=NULL)
    puts(line);
 if(fgets(line, MAXLINE, inputFILE)!=NULL)
    puts(line);

fgets returns NULL only if a read error occurs or end of file is reached. 'Blank' line (that is line containing only new-line character) is still valid for fgets. You need to check characters in your line buffer. Line could be terminated with \n or \r\n.

EDIT:
puts appends new-line character at end of the string so you end up with 2 new-line characters resulting in displaying 'blank' line. Use printf instead.

Code:

---

if (fgets(line, MAXLINE, inputFILE) != NULL && line[0] != '\r' && line[0] != '\n')
{
    printf("%s", line);
}

If would be easier to use fputs() instead - as that does not append a newline.
