A simple do/while/loop structure i'm having trouble with.

[ijm_155]

I have to create an application that lets a user enter as much grades he wants. The grades are between 0 and 100 and they can't be negative. Whenever the user type -1, the application is done and it shows the average of the grades, the lowest and the highest grades.

I absolutly have no idea where to start but i must be using loop/do/while.

I'm willing to send 5$ through paypal if you can guide me into the right direction =D

We don't do homework (and somebody would have to be mighty hard up to do anything for $5), but we are willing to help out if you start off. You might start by listing the steps that the program will have to perform in order. That doesn't mean the question, but the things that the program will have to be able to do to work as described. For instance, it obviously must ask the user for some input. Does it need to do anything after that? How will you get that input (most classes cover only one or two ways, so you probably have very limitted options here)? What will you do with that input once you get it? And so forth.

Don't worry about the money ... but:

Dim Results As New List(Of Integer)
        Console.WriteLine("Enter Results (-1 when done):")
        Do
            Dim strResult = Console.ReadLine()
            Dim CurrentResult As Integer
            If Integer.TryParse(strResult, CurrentResult) Then
                If CurrentResult = -1 Then
                    'show results
                    Console.Clear()
                    If Results.Count > 0 Then
                        Console.WriteLine("Average: " & Results.Average)
                        Console.WriteLine("Highest: " & Results.Max)
                        Console.WriteLine("Highest: " & Results.Min)
                        Console.ReadKey()
                    End If
                    Return
                Else
                    Results.Add(CurrentResult)
                End If
            Else
                Console.WriteLine("You must enter an integer!")
            End If
        Loop
