'【程序填空】

'-------------------------------------------------------

'功能：下面的程序段用于实现以下功能：利用冒泡法将一组整数 ' 从小到大排序。

'------------------------------------------------------- Private Sub Form_Click() Const n = 15

Dim a(1 To n) As Integer, work As Boolean Dim i As Integer, j As Integer, x As Integer Randomize For i = 1 To n

a(i) = Int((90 * Rnd) + 10) Next i

For i = 1 To n Print a(i); Next i Print

'**********SPACE********** For i = n To 2 【?】step-1 work = True For j = 1 To i - 1

If a(j) > a(j + 1) Then

x = a(j): a(j) = a(j + 1): a(j + 1) = x '**********SPACE********** 【?】work=False End If Next j

'**********SPACE********** If work Then 【?】Exit For Next i

For i = 1 To n Print a(i); Next i End Sub 答案

1). Step -1

2). work = False 或 work=0 或 not work = true 3). Exit For

'功能：以下程序用于判断一个正整数（≥3）是否为素数。

'-------------------------------------------------------

Private Sub Form_Click()

n = InputBox(\请输入一个正整数（≥3）\k = Int(Sqr(n)) i = 2 swit = 0

'**********SPACE********** Do While i <= k And 【?】swit=0 '**********SPACE********** If 【?】n Mod i =0 Then swit = 1 ?不是素数 Else

'**********SPACE********** 【?】i = i + 1 End If Loop

If swit = 0 Then

Print n; \是一个素数\Else

Print n; \不是素数\End If End Sub

答案：

1). swit = 0

2). n Mod i = 0 或 n/i ★= ★ n\\i 或 n/i ★=★ int(n/i) 3). i = ★i ★+★ 1

'功能：本程序用于实现：从键盘接收一数字，判断其是否在数组 ' 中，如果在数组中则将其删除，否则显示该数字不在数组 ' 中。

'------------------------------------------------------- Private Sub Form_Click()

Dim a(10) As Integer, x As Integer For i = 1 To 10

a(i) = Int((Rnd * 90) + 10) Print a(i); Next i Print

x = InputBox(\请输入要删除的整数\For i = 1 To 10

'**********SPACE********** If a(i) = x Then 【?】Exit For Next i

'**********SPACE**********

If 【?】i< 10 Then For k = i To 9

'**********SPACE********** 【?】a(k) = a( k + 1 ) Next k

Print \删除后的数组:\ For i = 1 To 9 Print a(i); Next i Else

Print \该数字不在数组中\End If End Sub

答案：

1). Exit For

2). i<10 或 10>i

3). a(k) = a(★ k ★+ ★1★)

'功能：利用下面的过程求m!和m*n

'------------------------------------------------------- Private Sub Form_Click()

Dim m As Integer, n As Integer m = 2 n = 3

'**********SPACE********** 【?】call find(m,n) End Sub

Private Sub find(x As Integer, y As Integer) Dim s, i As Integer

'**********SPACE********** 【?】s=1 For i = 1 To x s = s * i

'**********SPACE********** p=【?】x*y Next i Print s, p End Sub

答案：

1). find m, n 或 call find(m,n) 2). s = 1 或 s = 1:p=0 3). p★+★y 或 x*y
