Repetitive structures


Objetive:

Create a Visual Basic (VB.net) program that prompts the user for two numbers and displays the numbers between them (inclusive) three times using "for", "while", and "do while" loops.

Enter the first number: 6
Enter the last number: 12

6 7 8 9 10 11 12
6 7 8 9 10 11 12
6 7 8 9 10 11 12


Code:

Imports System
Public Class exercise37
    Public Shared Sub Main()
        Dim number, number2 As Integer
        Dim i As Integer
        Console.Write("Enter first number: ")
        number = Convert.ToInt32(Console.ReadLine())
        Console.Write("Enter last number: ")
        number2 = Convert.ToInt32(Console.ReadLine())

        For i = number To number2
            Console.Write("{0} ", i)
        Next

        Console.WriteLine()
        i = number

        While i <= number2
            Console.Write("{0} ", i)
            i += 1
        End While

        Console.WriteLine()
        i = number

        Do
            Console.Write("{0} ", i)
            i += 1
        Loop While i <= number2

        Console.WriteLine()
    End Sub
End Class
