Question 5 Explanation:

→ An escape sequence is a sequence of characters that does not represent itself when used inside a character or string literal, but is translated into another character or a sequence of characters that may be difficult or impossible to represent directly.
→ All escape sequences consist of two or more characters, the first of which is the backslash, \ (called the “Escape character”); the remaining characters determine the interpretation of the
escape sequence. For example, \n is an escape sequence that denotes a newline character.
→ If we treat it a character constant means one character
Note: An escape sequence is regarded as a single character and is therefore valid as a character constant.
