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.
|\a||Bell (speaker beeps)|
|\f||Form feed/clear screen|
|\xnn||Hexadecimal character code nn|
|\onn||Octal character code nn|
|\nn||Octal character code nn|
