'nested "select case"

Module Module1

    Sub Main()
        Dim choice1 As Integer = 2
        Dim choice2 As Single = 2.2

        Select Case choice1
            Case 1
                Select Case choice2
                    Case 1.1
                        Console.WriteLine("Option 1.1")
                    Case 1.2
                        Console.WriteLine("Option 1.2")
                    Case 1.3
                        Console.WriteLine("Option 1.3")
                End Select
            Case 2
                Select Case choice2
                    Case 2.1
                        Console.WriteLine("Option 2.1")
                    Case 2.2
                        Console.WriteLine("Option 2.2")
                    Case 2.3
                        Console.WriteLine("Option 2.3")
                End Select
            Case 3
                Select Case choice2
                    Case 3.1
                        Console.WriteLine("Option 3.1")
                    Case 3.2
                        Console.WriteLine("Option 3.2")
                    Case 2.3
                        Console.WriteLine("Option 3.3")
                End Select
            Case Else
                Console.WriteLine("Invalid choice")
        End Select
    End Sub
    
End Module

Output:

Option 2.2
Press any key to continue . . .

Explanation:

In the above program, we created a module Module1 that contains a Main() method. In the Main() method, we created two variables choice1 and choice2 that are initialized with 2 and 2.2 respectively.

In the above program, we defined "select case" inside the "select case", which is known as a nested select case. Here, "case 2.2" will be executed and then print the appropriate message on the console screen.
