很急,请问VB怎么输出3到100之间所有素数

Answer 1

dim i,j,x
for i=3 to 100
    x=1
    for j=2 to i-1
        if i mod j=0 then x=0
    next j
    if x=1 then print i
next i

Answer 2

Private Sub Command2_Click()
For i = 1 To 100
If prime(i) Then Print i
Next
End SubPublic Function prime(ByVal m As Integer) As Boolean '鍒ゆ柇m鏄�惁涓虹礌鏁?
Dim b As Boolean
Dim i As Integer
b = True
For i = 2 To Sqr(m)
If m Mod i = 0 Then
b = False
Exit For
End If
Next i
prime = b
End Function

Answer 3

Private Sub Command1_Click()
Cls
For i = 2 To 100
j = i \ 2
Do While j >= 2
If i Mod j = 0 Then Exit Do
j = j - 1
Loop
If j = 1 Then Print i
Next i
End Sub
