'integer number is SET or not.

Module Module1

    Sub Main()
        Dim num As Integer = 0
        Dim bit As Integer = 0

        Console.Write("Enter Number: ")
        num = Integer.Parse(Console.ReadLine())

        Console.Write("Enter Bit position between 0-31: ")
        bit = Integer.Parse(Console.ReadLine())

        If ((1 << bit) And num) Then
            Console.WriteLine("bit {0} is set", bit)
        Else
            Console.WriteLine("bit {0} is not set", bit)
        End If

        Console.ReadLine()
    End Sub

End Module

Output:

Enter Number: 15
Enter Bit position between 0-31: 3
bit 3 is set

Explanation:

In the above program, we created a module Module1 that contains a function Main(). In the Main() function, we declared two integer variables num and bit that are initialized with 0. After that we read values for variables num and bit. Then we checked the given bit of the given number is SET or NOT, and print an appropriate message on the console screen.
