b) Integer literals - It represents to literals which are used to write values of types int, uint, long, and ulong.
c) Real literals - It represents to the literals which are used to write values of types float, double, and decimal.
d) Character literals – It represents a single character which usually consists of a character in quotes, such as 'a'.
e) String literals - It represents string literals that can be of two types in C #:

• A regular string literal comprises of zero or more characters enclosed in the double quotes, like "hello".
• A verbatim string literal comprises of the @ character followed by a double-quote character, like @"hello".
