C# allows embedding special (often non-printable) characters into a string literal using an escape sequence. An escape sequence is a series of characters that begins with a backslash (\), followed by one or more letters or digits.
Here’s an example of embedding several newline characters into a string, so that it’s printed on three different lines.
