Append a string at the end of every line in a file

Hi Friends, I have a file with many lines as shown below.
/START SAMPLE LINE/
Code:
M:\mmarimut_v6.4.0_pit_01\java\build.xml@@\main\v6.4.0_pit_a
M:\mmarimut_v6.4.0_pit_01\port\Post.java@@\main\v6.4.0_pit_a
M:\mmarimut_v6.4.0_pit_01\switchview\View.java@@\main\v6.4.0_pit_a

/END SAMPLE LINE/

I need to append a string "\0" to the end of every line. Sample output is as follows:

/START SAMPLE OUTPUT/
Code:
M:\mmarimut_v6.4.0_pit_01\java\build.xml@@\main\v6.4.0_pit_a\0
M:\mmarimut_v6.4.0_pit_01\port\Post.java@@\main\v6.4.0_pit_a\0
M:\mmarimut_v6.4.0_pit_01\switch\View.java@@\main\v6.4.0_pit_a\0

/END SAMPLE OUTPUT/

I tried the below commands but somehow not sure, i did not get the desired output. Experts Please help.

/SAMPLE CODE/
Code:
awk '{print $0 "\\0"}' file > newfile
nawk '{$0=$0"\\0" }1' infile > newfile
gawk '{$0=$0"\\0" }1' infile.txt > outfile.txt

/SAMPLE CODE/
