You need to format your code for it to show up correctly in your posts, @Mazhar_Shaikh.
You can highlight your code, then use the </> button in the editor window, which will format it.
Or you can place three backticks ``` (top left key on US/UK keyboards) on a line before your code, and three on a line after your code. I find this approach easier, but unfortunately some European and other keyboards don’t have that character.
