C# Literals

C# Literals are value constants assigned to variables in a program. In C#, there are six types of literals are exist.

Integer Literals:

An Integer literal refers to a sequence of digits. There are two types of integers namely:

• Decimal Integers
• Hexadecimal Integers

Decimal Integers:

Decimal Integers consist of a set of digits, 0 to 9 preceded by an optional minus sign.
Example:

123, -321, 654321

Hexadecimal Integers:

Hexadecimal Integers refer to a sequence of digits preceded by 0x or 0X is considered as a Hexadecimal Integers. It may also include alphabets A, B, C, D, E, F or a, b, c, d, e, f.

• A or a represents the number 10
• B or b represents the number 11
• C or c represents the number 12
• D or d represents the number 13
• E or e represents the number 14
• F or f represents the number 15

Example:

0x, 0X2, 0X9F, 0Xbcd

Real Literals:

It is represented by numbers containing fractional parts that are called Real Literals.

Example:
0.50, 3.14, -0.15

A real literal may also be expressed in exponential notation.

Example:
8.16e47, 0.5e+4, -1.5e-1

Boolean Literals:

There are two types of Boolean literals and that are:

• True
• False

Single Character Literals:

A single character contains a single character enclosed within a pair of single quotation marks.
Example:
‘5’ ‘X’ ‘;”’

Where the character constant [no-highlight]’5′[/no-highlight] isn’t the same as the number 5. The last constant in the [no-highlight]”[/no-highlight] is a blank space.

String Literals:

A string literal is a sequence of characters enclosed between double quotes. The characters may be alphabets, digits, special characters and blank spaces.

Example:
“Hello” “Well Done” “X”

Backslash Character Literals:

In C#, there are supports for some special backslash character constants that are used in output methods.
