What is the function \\

Answer 1

Hm... it's documented in other languages but I couldn't find this in the c++ lessons.

Most languages have the problem of how to print or represent characters that you can't / shouldn't typed into the source code.

To get around the problem, language writers chose an uncommon character -- the backslash -- to precede another character that represents something special, e.g.:

\t horizontal tab
\n newline

but now... backslashes are special; how do you represent backslashes?

\\ backslash

Future note:
The same pattern also appears in 'regular expressions' (regex)
