Escape sequences are used in the programming languages C and C++. These are character combinations that comprise a backslash (\) followed by some character. They give results such as getting to the next line or a tab space. They are called escape sequences because the backslash causes an "escape" from the normal way characters are interpreted by the compiler.
Common escape sequences
- \a – Bell (beep)
- \b – Backspace
- \f – Formfeed
- \n – New line
- \r – Carriage return
- \t – Horizontal tab
- \\ – Backslash
- \' – Single quotation mark
- \" – Double quotation mark
- \0 – ASCII-0 character
- \ooo – Octal representation
- \xdd – Hexadecimal representation
Escape sequences are special strings used to control output from the C program on the monitor, or on any output device, e.g. the printer.
