Ex 5! = 5 * 4 * 3 * 2 * 1 = 120
When I arrived at home, I couldn't help, but spend ten minutes working in Visual Basic to create a form that instantly finds the factorial of any number entered into a text box. Here is what I came up with.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim StartVal As Long
StartVal = intxt.Text
Dim N As Long
N = StartVal - 1
Do While N > 0
StartVal = (StartVal * N)
N = N - 1
Loop
outtxt.Text = StartVal
End Sub
Dim StartVal As Long
StartVal = intxt.Text
Dim N As Long
N = StartVal - 1
Do While N > 0
StartVal = (StartVal * N)
N = N - 1
Loop
outtxt.Text = StartVal
End Sub
<Sigh>
