Integer type literal

Literals are hard coded value to a certain type.

For example, 0 is a literal for int type.

The following code uses int literal to initialize an int type variable.

using System;

class Program
{
    static void Main(string[] args)
    {
        int i = 5;

        Console.WriteLine(i);
     }
}

The output:

5

Hexidecimal literal

We can also use hexidecimal literal in C#.

The hexidecimal has 0X prefix.

using System;

class Program
{
    static void Main(string[] args)
    {
        int i = 0XFF;

        Console.WriteLine(i);
     }
}

The output:

255
