I know this is way late for your assignment, but I'm new to the forum. All I was going to add is this "end of line" error probably has to do with your Visual code using DOS CarriageReturn+LineFeed (0x0D0A respectively) for end of record delimiter while Linux (even psuedo-Linux like cygwin) uses just newline (0x0A). (Actually, I think Cygwin has an option for CRLF, but that's another matter.) You can use the Unix translate utility, "tr," to axe the extra character, i.e. ixnay the CR, like so:
tr -d '\r' <dosfile_crlf.c >unixfile_nl.c
Hope this proves helpful in the future since I was not in time for your assignment.

getdelim
GETDELIM(3) BSD Library Functions Manual GETDELIM(3)
NAME
getdelim, getline -- read a delimited record from a stream
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <stdio.h>
ssize_t
getdelim(char ** restrict lineptr, size_t * restrict n, int delimiter, FILE * restrict stream);
ssize_t
getline(char ** restrict lineptr, size_t * restrict n, FILE * restrict stream);
DESCRIPTION
The getdelim() function reads from the stream until it encounters a character matching delimiter, storing the input in *lineptr. The buffer
is NUL-terminated and includes the delimiter. The delimiter character must be representable as an unsigned char.
If *n is non-zero, then *lineptr must be pre-allocated to at least *n bytes. The buffer should be allocated dynamically; it must be possible
to free(3) *lineptr. getdelim() ensures that *lineptr is large enough to hold the input, updating *n to reflect the new size.
The getline() function is equivalent to getdelim() with delimiter set to the newline character.
RETURN VALUES
The getdelim() and getline() functions return the number of characters read, including the delimiter. If no characters were read and the
stream is at end-of-file, the functions return -1. If an error occurs, the functions return -1 and the global variable errno is set to indi-
cate the error.
The functions do not distinguish between end-of-file and error, and callers must use feof(3) and ferror(3) to determine which occurred.
EXAMPLES
The following code fragment reads lines from a file and writes them to standard output.
char *line = NULL;
size_t linesize = 0;
ssize_t linelen;
while ((linelen = getline(&line, &linesize, fp)) != -1)
fwrite(line, linelen, 1, stdout);
if (ferror(fp))
perror("getline");
ERRORS
[EINVAL] lineptr or n is a NULL pointer.
[EOVERFLOW] More than SSIZE_MAX characters were read without encountering the delimiter.
The getdelim() and getline() functions may also fail and set errno for any of the errors specified in the routines fflush(3), malloc(3),
read(2), stat(2), or realloc(3).
SEE ALSO
ferror(3), fgets(3), fopen(3)
STANDARDS
The getdelim() and getline() functions conform to IEEE Std 1003.1-2008 (``POSIX.1'').
