# Literals in C#

CsharpProgrammingServer Side Programming

The fixed values are called literals. The constants refer to fixed values that the program may not alter during its execution.

Constants can be of any of the basic data types like an integer constant, a floating constant, a character constant, or a string literal. There are also enumeration constants as well.

Let us learn about integer, float, and string literals in C# −

## Integer Literals

An integer literal can be a decimal, or hexadecimal constant. A prefix specifies the base or radix: 0x or 0X for hexadecimal, and there is no prefix id for decimal.

Here are some example of Integer Literals −

20 // int
30u // unsigned int
30l // long

## Float Literals

A floating-point literal has an integer part, a decimal point, a fractional part, and an exponent part. You can represent floating point literals either in decimal form or exponential form.

Here are some examples of Float Literals −

## String Literals

String literals or constants are enclosed in double quotes "" or with @"". A string contains characters that are similar to character literals: plain characters, escape sequences, and universal characters.

Here are some examples of String Literals −
