C Language Escape Sequences

When you're programming in the C language, sometimes you need to refer to a key press that doesn't result in a specific character. Other times, you need to refer to a specific character literally that normally has a different meaning in C. In either case, you need an escape sequence. The following table lists the escape sequences you need to program in the C language.

Escape sequences always begin with a backslash.

Escape Sequence	Character

\b	Backspace (non-erase)

\n	New line
\r	Carriage Return
