Escape sequences are used in the programming languages C and C++, and their design was copied in many other languages such as Java and C#. Escape sequences are the special characters used in control string to modify the format of the output. These characters are not displayed in output. These characters are used with combination of backslash \. This backslash \ is called escape character.
