1.某数组有20个元素，其值为随机产生的两位整数。现要求将前10个 元素与后10个元素对换。即第1个元素与第20个元素互换，第2个数与第19个元素互换，…，第10个元素与第11个元素互换。在窗体上输出数组原来各元 素的值与对换后各元素的值。
Opti on explicit
Dim a(1 to 20) as in teger, I as in teger, j as in teger, t as in teger
a(k) = a(k-1)
Next k
a(k) = m
For i = 1 To n
Print a(i);
Next i
Print
End Sub
4.6个评委为4位歌手打分，分数介于1-100之间。去掉一个最高分，一 个最低分，求出每位选手的最后得分。将4位歌手得分从高到低排列输出，同
时输出该选手的编号
如：
Print a(i);
Next i
End If
End Sub
3.数组a中存放着升序排列的数据,使用array赋值，将inputbox输入的新数插入到数组中，插入后数组仍有序。
注意：要求利用动态数组，能够实现多次插入
Private Sub Form_Load()
Show
n = 8: ReDim a(n)
Print a(i);
m = m+1
Next i
Print
n = InputBox("查找的数是:")
i = 0: flag = False
Do
If a(i) = n The n
j = i: flag = True
For k = j To UBound(a) - 1
a(k) = a(k+1)
Next k
For i = 1 To 10
j = 21-i
t = a(i): a(i) = a(j): a(j) = t
Next i
For i= 1To 20
Print a(i);
If i Mod 10 = 0 Then Print
Next i
End Sub
2.从数组中删除一个数。先定义一个一维数组，大小、数组的值自定。 从键盘上输入一个数，若这个数在数组当中，就把它删除；若这个数不在数组 中，提示该数不在数组中”
ReDim Preserve a(UBou nd(a)-1)
i = i-1
End If
i = i+1
Loop While (i <= UBou nd(a))
If flag = False Then
MsgBox n & "不在该数组中"
Else
Print "删除"& n & "后的数组是："
For i = 0 To UBou nd(a)
Private Sub Comma nd1_Click()
For i = 1 To 4
Forj = 1 To 6
singer(i).fenshu(j) = Int(Rnd * 100)
singer(i).xuhao ="歌手"&i
Next

Print "原始数组是wenku.baidu.com"
Ran domize
For i = 1 To 20
a(i) = Int(Rnd * 90)+10
Print a(i);
If i Mod 10 = 0 Then Print
Next i
Print
Print "现在数组是："
a = Array(5, 15, 23, 52, 68, 88, 90, 99)
n = n+1: ReDim Preserve a( n)
m = InputBox("请输入要插入的数据:")
For i = 1 To n - 1
If m < a(i) The n Exit For
Next i
For k = n To i+1 Step -1

1)如果数组中存在多个与该数相同的元素，每一个都能删除；
2)能实现多次删除
Private Sub Form_Load()

ReDim a(9) As In teger
m = 1
Print "原来数组为："
For i = 0 To 9
a(i) = InputBox("请输入第"&m&"个数：")
