Answer to Question #294926 in Visual Basic for JRD

Question

The following code is supposed to take input from the user and print out each entry and add them together with a final print out of the total of all input numbers. The code does exactly that, but I don't get how it prints each input without the writeline being inside the loop. If I move the writeline into the loop, it double prints the input. Any help understanding this would be greatly appreciated. Thanks

Sub Main()

    Dim sum As Integer

    Dim inValue As Integer

    Console.WriteLine("Enter a number: ")

    Do

      inValue = Console.ReadLine()

      If inValue <> -1 Then

        sum += inValue

      End If

    Loop Until inValue = -1

    Console.WriteLine(sum)

    Console.WriteLine("press enter to exit")

    Console.ReadLine()

  End Sub
