DO循环的四种形式

Do do do while 条件do until 条件语句行

Loop while 条件loop until 条件loop loop WHILE 条件为真时继续运行循环程序

Until 条件为真时,退出程序

Private Sub Command0_Click()

Rem 在程序运行时提示用户输入1-12的数字,程序判断且输出对应数字所属

Rem 月份对应的季节

Dim k As Integer, jx As Integer

Do

k = InputBox("请输入1-12的数字", "提示", 1)

Select Case k

Case 3 To 5

MsgBox "春季", vbOKOnly, "季节输出"

Case 6 To 8

MsgBox "夏季", vbOKOnly, "季节输出"

Case 9 To 11

MsgBox "秋季"

Case 1, 2, 12

MsgBox "冬季", vbOKOnly, "季节输出"

Case Else

MsgBox "您输入的数据有误!"

End Select

jx = MsgBox("是否继续判断?", vbYesNo, "提示")

Loop Until jx = 7

End Sub

计算1-100中所有数据的和

Dim k As Integer, s As Integer '0

k = 1: s = 0

Do Unti l k > 100

s = s + k

k = k + 1

Loop

MsgBox "1-100的和为" & s

End Sub

Dim k As Integer, s As Integer '0

k = 1: s = 0

Do while k <=100

s = s + k

k = k + 1

Loop

MsgBox "1-100的和为" & s

End Sub

Dim k As Integer, s As Integer '0

For k = 1 To 100 Step 1

s = s + k

Next k

MsgBox "1-100的和为" & s

Private Sub Command0_Click()

Dim k As Integer, s As Integer '0

For k = 1 To 20 Step 3 '1 4 7 10 13 16 19 22 s = s + k '1 5 12 22 35 51 70 Next k '4 7 10 13 16 19 22 MsgBox "和为" & s

MsgBox "k的值为" & k

End Sub

Private Sub Command0_Click()

Dim h As Integer, k As Integer

h = 1: k = 1

For h = 1 To 9

Debug.Print

Debug.Print h & ")";

For k = 1 To h

Debug.Print h * k;

Next k

Next h

End Sub

一维数组的赋值

Option Compare Database

Private Sub Command0_Click()

Dim ar1(10) As Integer

Dim k As Integer

For k = 0 To 10

ar1(k) = InputBox("请输入第" & k + 1 & "个元素的值")

Debug.Print ar1(k);

Next k

End Sub

双层FOR循环给数组赋值

Option Compare Database

Option Base 1

Private Sub Command0_Click()

Dim ar1(3, 4) As Integer

Dim k As Integer, h As Integer

For k = 1 To 3

For h = 1 To 4

ar1(k, h) = InputBox("请输入第" & k & "行第" & h & "列元素的值") Debug.Print ar1(k, h);

Next h

Debug.Print

Next k

End Sub
