What is the purpose of that space character between \t and \\?

[matsrdr]

Hi, in the string:
“FirstLine\n\t \SecondLine\nThirdLine”

The back-slashes have the following function:
\n : This will be “substituted” with a “newLine-character”
\t : This will be “substituted” with a “tab-character”
\ : This will be substituted with a single "" character.

Hope this answers Your question.
Best regards

Just to complement by answer above.
I can of course not with certainty say what the “purpose is”. But the only “real difference” that the “space character” does, is that it “indents” the second row 1 “space character” further (i.e. the full indent is 1"tab"+1"space". Instead of just 1"tab"…
So with the original string it would “print”:
FirstLine
\SecondLine
ThirdLine

But if You take away the “space character”, so the string would be:
“FirstLine\n\t\SecondLine\nThirdLine”;
It would “print”:
FirstLine
\SecondLine
ThirdLine

Do You see the difference ?.. It’s hardly visible, and I really can not speak to it’s purpose.
Best regards.
