' The IF statement is the first thing i learned in programming.' IF? is your questions to the application, so that you can' decide what is going to happen next..' if a counter is 10 then set it back to 0' if you don't have any money left, you can't buy that dvd-player.' if your character fall more than 3 units in a game, then he loses energy etc.PublicClass Form1
Dim num AsIntegerDim strReply AsStringPrivateSub Form1_Load(ByVal sender As System.Object, _
ByVal e As System.EventArgs) HandlesMyBase.Load
'Ask our question when the program loads
Label1.Text = "How many cars do you have?"EndSubPrivateSub Button1_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles Button1.Click
num = Int(TextBox1.Text) 'InputIf (num > 0) Then
strReply = "You have a car!"Else
strReply = "You don't have a car!"EndIfIf (num > 1) Then strReply = "Are you rich!"'display our comment
Label1.Text = strReply
