3.1.9 Escape Sequences
Escape sequences are used to represent nonprintable ASCII characters. Table 3.3 shows some commonly used escape sequences and their representation in C language. For example, the character combination “n” represents the newline character.
Table 3.3: Some commonly used escape sequences
| Escape sequence | Hex value | Character |
|---|---|---|
| a | 0x07 | BEL (bell) |
| b | 0x08 | BS (backspace) |
| t | 0x09 | HT (horizontal tab) |
| n | 0x0A | LF (linefeed) |
| v | 0x0B | VT (vertical feed) |
| f | 0x0C | FF (formfeed) |
| r | 0x0D | CR (carriage return) |
| xH | String of hex digits |
An ASCII character can also be represented by specifying its hexadecimal code after a backslash. For example, the newline character can also be represented as “x0A”.
