1）用一个一维数组来模拟，编号1~N保存在数据a(1)~a(n)中，来代表N个小朋友。

2）K代表报数的起始位置，从数组的a(k)开始遍列，报到m出圈，将当前位置的元素删除，后面的元素依次往前移位。总数减1。

3）当报数报到数组元素的最后一个时，返回数组开头接着报数。

4）当总数只剩下一个数时，直接输出。

界面如下：

Private Sub Command1_Click(   )

Dim i As Integer

Dim n As Integer

Dim m As Integer, k As Integer

Dim A(1 To 50) As Integer   '存放编号的数组

n = Val(Text1.Text)                       '编号个数

k = Val(Text2.Text)                '报数起始位

m = Val(Text3.Text)                   '报到出圈数

If n > 0 And k > 0 And m > 0    ①   n <= 50 Then

    For i = 1 To n              '初始化编号a(1)=1,a(2)=2,……

         A(i) = i

    Next i

    Label1.Caption =     ②          '调用出圈函数，得到返回的出圈顺序

Else

    MsgBox "编号、起始位、报到出圈数都必须大于0！编号不能超过50！"

End If

End Sub

Private Function chuquan(b() As Integer, n As Integer, m As Integer, k As Integer) As String

Dim i As Integer, j As Integer

Dim s As String                  '出圈顺序存放

i = k - 1

s = "出圈顺序为："

Do While n > 1

       i = i + 1

       m = m - 1

       If     ③  Then

         s = s + Str(b(i)) + ","

         For j = i To n - 1

            b(j) = b(j + 1)

         Next j

         b(j) = 0

         n = n - 1

         i = i - 1

         m = 4

      End If

      If i = n  Then  i = 0

Loop

chuquan =        ④    

End Function

实现上述功能的VB程序如下，但加框处代码有错误，请改正。

  Dim a(1 To 15) As Integer

Dim n As Integer 'n为计数器

Dim key As Integer 'key存放筛选条件的数字部分

Dim f As String 'f存放筛选天健的符号部分：大于号或者小于号

Private Sub FormLoad()

Randomize

For i = 1 To 15

a(i) = Int(Rnd * 100)

List1.AddItem Str(a(i))

Next i

 End Sub

Private Sub Command1Click()

Dim c As Integer

Dim st As String

n = 0

c = Len(st)

f = Mid(st, 1, 1)

If f = "<" Then Se2 '调用过程

If f = ">" Then Se1 '调用过程

Label2.Caption = "有" + Str(n) + "个筛选结果"

End Sub

Private Sub Se1() '筛选过程1

For i = 1 To 15

   If a(i) > key Then

      List2.AddItem Str(a(i))

      n = n + 1

   End If

Next i

End Sub

Private Sub Se2() '筛选过程2

For i = 1 To 15

List2.AddItem Str(a(i))

       n = n + 1

    End If

Next i

End Sub

具体方法为：（1）若身份证号为15位，则根据第15位数字来判断，若为偶数则性别“女”，否则为“男”；（2）若身份证号为18位，则根据第17位数字来判断，若为偶数时则性别为“女”，否则为“男”。

For i = 1 To Len(Text1.Text)

  c = Mid(Text1.Text, i, 1)

  If c >= "0" And c <= "9" Then c = Chr(Asc(c) + 1)

  If c >= "A" And c <= "Z" Then c = Chr(Asc(c) + 32)

  s =s + c

Next i
