Help with easy project - reading a file.

I need to do a project that is suppose to read a file and it is suppose to display the number of the line plus whatever the file is reading indented by a tab:
example file:
"This is
the test
file."

expected output:
1 "This is
2 the test
3 file."

I am having two problems.

1. I need to check first if the file is empty.

2. The program includes the last line in the file, even though its empty. It comes out like this:
1 "This is
2 the test
3 file."
4

This is my program:
#include <stdio.h>

main()
{
int c, nl_cnt = 1;
if ((c = getchar()) == 'null') /*<-----"Doesn't work */
printf("File is empty\n");
else
{
printf("%d\t", nl_cnt);
while ((c = getchar()) != EOF)
if (c == '\n')
{
++nl_cnt;
printf("\t\n");
printf("%d\t", nl_cnt);

}
else
printf("%c", c);
}
}

I need help please!

lnptest2(1)						      General Commands Manual						       lnptest2(1)

NAME

       lnptest2 - LNP Client Test Application #2 (shorter test)

SYNOPSIS

       lnptest2

DESCRIPTION

       lnptest2  is  an LNP Daemon test client used to test the connection between a client LNP program (in this case lnptest2) and the LNP daemon
       through the Ir Tower to a corresponding test program running in an RCX.	See the FILES section for the location of  the	RCX  test  program
       source code (distributed with this package).

OPTIONS

       lnptest2 does not support command-line options.

USAGE

       To run the test:
       - compile the lnptest2.c RCX program
       - start the lnpd daemon
       - download the lnptest2.lx program to the RCX
       - at the RCX, run the program just downloaded to the RCX
       - run this lnptest2 program
       - inspect the output looking for lack of failure messages

FILES

       /usr/share/doc/lnpd/examples/rcx
	      In this directory is the source to the RCX-side program which is called lnptest2.c but written to be compiled against BrickOS.

SEE ALSO

       lnptest(1), lnpdll(1), lnpd(8)

       You can find additional documentation in /usr/share/doc/lnpd (on Debian GNU/Linux systems)
