write a program which will print power of 2

2 ^ 0 1
2 ^ 1 2
2 ^ 2 3
2 ^ 3 4
i done this already.
Private Sub Command1_Click()
Dim numbers As Integer
Dim answers As Integer
numbers = 0
Do While numbers < 9
answer = 2 ^ numbers
Print answer
numbers = numbers + 1
Loop
End Sub
The following will help with the computation. If you need help on the printing side, please specify if you are to print to your printer, the form etc. -
Function Power2(ByVal exponent As Long) As Long
Static res(0 To 31) As Long
Dim i As Long
' Raise 2 to a power
' the exponent must be in the range [0,31] or change the Static Res above.
' rule out errors
If exponent < 0 Or exponent > 31 Then Err.Raise 5
' initialize the array at the first call
If res(0) = 0 Then
res(0) = 1
For i = 1 To 30
res(i) = res(i - 1) * 2
Next
' this is a special case
res(31) = &H80000000
End If
' return the result
Power2 = res(exponent)
Text2.Text = Power2
End Function
Private Sub Command1_Click()
'First check to see if an inteher has been added to textbox.
If Text1.Text = "" Then
MsgBox "Please add a number to compute exponent.", vbOKOnly + vbExclamation, "Add Integer"
Text1.SetFocus
Exit Sub
'Check if data entered is an integer.
ElseIf Not IsNumeric(Text1.Text) Then
MsgBox "Only numbers accepted as an entry.", vbOKOnly + vbExclamation, "Add Integer"
Else
Call Power2(Text1.Text)
End If
End Sub
Hope this helps...
