VB应用程序界面如上图所示，在文本框text1中输入查询的日期（以月日形式，如0623），单击“查询”按钮，在列表框中显示所有这个日子出生的员工姓名（按姓名排序），并在Label3处显示员工数量，如果人数为0，则在列表框中显示“本天没有员工生日”。

解决此问题的VB程序如下，阅读程序并完成后面的问题。

‘定义存放员工姓名的数组na

Private Sub CmsqClick()

  Dim n As Integer , i As Integer , j As Integer

  Dim t1 As String

  ‘连接数据库获取数据

  Dim cn As new connection

  Dim rs As new recordest

  Dim str1 As String , str2 As String

     str1 =”driver=Microsoft access driver(*.mdb)”；dbq=”&app.path”&”员工信息.mdb”

     cn.open str1

     str2 = “select * form members where 生日 ＝’“ + text1.text + ”’”

     rs.open str2 ， cn.adOpenDynamic ，adLockOptimistic

     n = 0

     Do While Not Rs.EOF

       n = n + 1

       na(i) = rs.Fields(“姓名”).value

       rs.MoveNext

     Loop 

     rs.close

     cn.close

‘按姓名排序

If n = 0 Then

  List1.AddItem “本天没有员工生日”

Else

  For i = 1 to n-1

    For j = 1 to n+1 Step -1

      If na(j) < na(j-1) Then

        t1 = na(j) :     ①      : na(j-1) = t1

      End If

    Next j

   Next i

   For i = 1 to n

     List1.AddItem     ②   

   Next i

   Label3.Caption = “这天共” + Str(n) + “位员工生日”

  End If

End Sub

    注：BMI指数的计算公式为：BMI=体重（千克）除以身高（米）的平方（kg/m2）。 BMI<18.5为偏瘦（表明营养不足）；BMI=18.5～24.9为体重正常；BMI=25～29.9为超重；BMI>30为肥胖。

该VB应用程序的代码如下：

Dim stuBMI(1 To 55) As Single

Dim stuName(1 To 55) As String

Private Sub Command1_Click()

    Dim k As Integer, i As Integer, j As Integer

    Dim t1 As Single, t2 As String

    Dim Results As String

    For i = 1 To 54        

        For j = i + 1 To 55

            If stuBMI(j) < stuBMI(k) then      ②    

        Next j

        If  k<>I  Then  

            t1 = stuBMI(i): stuBMI(i) = stuBMI(k): stuBMI(k) = t1

            t2 = stuName(i): stuName(i) = stuName(k): stuName(k) = t2

        End If

    Next i

List1.AddItem "姓名" + vbTab + "BMI指数" + vbTab + "结果"  

    For i = 1 To 55

        If stuBMI(i) < 18.5 Then

            Results = "偏瘦"

        ElseIf stuBMI(i) >= 18.5 And stuBMI(i) < 25 Then

            Results = "正常"

        ElseIf stuBMI(i) >= 25 And stuBMI(i) < 30 Then

            Results = "超重"

        Else

            Results = "肥胖"

        End If

        List1.AddItem stuName(i) + vbTab + str(stuBMI(i)) + vbTab + Results

    Next i

End Sub

Private Sub Form_load()

    Dim conn As New ADODB.Connection

    Dim rs As New ADODB.Recordset

    Dim i As Integer

    conn.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + App.Path + "\Student.accdb"

    conn.Open

    strSQL = "SELECT * FROM Student"

    Set rs.ActiveConnection = conn

    rs.Open strSQL

    i = 0

    Do While Not rs.EOF

        i = i + 1

        stuName(i) = rs.Fields("StuName")

        stuBMI(i) = Round(rs.Fields("Weight") / rs.Fields("height") ^ 2, 1)

        rs.MoveNext

    Loop

    rs.Close

    conn.Close

    Set rs = Nothing

    Set conn = Nothing

End Sub

数组元素d(1)到d(5)的值依次为“36，25，47，89，78”，经过该程序段“加工”后，下列说法正确的是是（   ）

t=0

For i=1 To 4

flag=False

For j=5 To i+1 Step-1

If a(j)>a(i) Then flag=True

  t=t+1

  temp=a(j):a(j)=a(i):a(i)=temp

End If

Next j

If flag=False Then Exit For

Next i

Const n = 10

Dim a(1 To n) As Integer

Private Sub Command1_Click()

Dim i As Integer, j As Integer, t As Integer

Dim bottom As Integer

'获取排序前数据依次存储在数组a中，并在文本框Text1中显示。代码略

bottom = n

i = 1

Do While i <= bottom - 1

   For j = bottom To i + 1 Step -1

      If  Then  {#blank#}1{#/blank#}

         t = a(j): a(j) = a(j - 1): a(j - 1) = t

      ElseIf a(j) = a(j - 1) Then    '相邻两个数据相等，进行剔除处理

            {#blank#}2{#/blank#}

         bottom = bottom - 1

      End If

   Next j

   i = i + 1

Loop

Text2.Text = " "

For i = 1 To bottom

Next i

End Sub
