How are characters represented in the C language?

In the C language, characters can be represented using character literals enclosed in single quotes. For example, ‘a’ represents the character a, ‘1’ represents the character 1. Additionally, there are special characters that can be represented using escape sequences, such as: – ‘\n’ represents the newline character – ‘\t’ represents the tab character – ‘\r’ represents the carriage return character – ‘\\’ represents the backslash character – ‘\” represents the single quote character – ‘\”‘ represents the double quote character. You can also represent characters using hexadecimal or octal escape sequences, for example: – ‘\x41’ represents the character A (hexadecimal ASCII code for 41) – ‘\101’ represents the character A (octal ASCII code for 101)
