Use of \\ in comments causes Trouble?

Question

I stumbled over this problem:
As soon as I added \\ in a comment, I got a whole bunch of errors, while everything is fine without.
See here:

Can anyone please explain this to me, I'm curious why this happens?

Answer 1

"If a line ends with a backslash, the following line is considered to be a continuation of that line. This is the standard behaviour."

From: stackoverflow.com/questions/28821786/double-backslash-in-comment-inside-array

Answer 2

Yeah, it spawns a compiler warning: multi-line comment.

I get that it looks neat. You could stick (any char, but maybe) a semicolon out there to reduce (not remove) the confusion for programmers who follow you.

Answer 3

Ah, I see, if I insert an empty line afterwards, everything is fine again.
Thanks for your answer!
