nileshjsr: Your problem is not that you're not using code tags, but rather that you're using too many of them! Your posts now look like

<code>File: input.log</code> <code>DATE1=2018-05-24</code> <code>DATE=
+2018-05-20</code> <code>SETTING USER RELATED INFORMATION ..</code>
[download]

when they should look like

<code>
File: input.log
DATE1=2018-05-24
DATE=2018-05-20
SETTING USER RELATED INFORMATION ..
with each line of data
represented by a line
in this block
</code>
[download]

(of course, I'm guessing about how your data breaks out into lines). Note that there's now a little  [download] link after each block of code.

Also, please do add some question to your post. Also, please do not post yet another node with fixed content; instead, please go back and edit/fix your original post; please see How do I change/delete my post? for details.
