Need help with code

[Ksmartman]

Ok my question states-

Request an odd number, and display a triangle similar to the one in figure 6. , with the input number of starts in the top row.

-So basically we ask the user for an odd number and take their input and make a triangle descending to zero.

Figure 6.

My code:

Dim i As Integer
Dim num As String = txtout.text


For i = 1
txtout.AppendText("*")
Next i
txtout.AppendText(ControlChars.NewLine)
For i = 1
txtout.AppendText("*")
Next i
txtout.AppendText(ControlChars.NewLine)

---Im stuck from here, any help is appreciated.

I just saw this post and thought I could help you out. Here is what I'd do:

Code: Select all

Public Class Form1
    Dim input, i, tempnum As Integer
    Dim output As String
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        input = 5
        i = 0
    End Sub
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Do Until i = input
            tempnum = input
            Do Until tempnum = 0
                output = output & "*"
                tempnum -= 1
            Loop
            output = output & vbNewLine
            input -= 1
        Loop
        MessageBox.Show(output)
    End Sub
End Class


I just added one button to the form to execute the command. In this example I set the input to 5. You can set this value to the number that the user enters.
