新建标准EXE，然后来两个文本框，一个按钮，文本框拉高一点，如图所示，再把它的MultiLine属性设置为True，把下面的代码复制过去就ok了
Private Sub Command1_Click()
If Text1.Text = "" Then
MsgBox "请输入10组数字！"
Exit Sub
End If
Dim Temp
Temp = Split(Text1.Text, vbCrLf)
If UBound(Temp) < 9 Then
MsgBox "你输入的不够10组"
Exit Sub
End If
Dim xiao, da, j, k
xiao = Temp(0)
da = Temp(0)
For i = 0 To 9
If CInt(Temp(i)) < CInt(xiao) Then
xiao = Temp(i)
j = i
End If
If CInt(Temp(i)) > CInt(da) Then
da = Temp(i)
k = i
End If
Next
Temp(k) = Temp(0)
Temp(0) = da
Temp(j) = Temp(9)
Temp(9) = xiao
Text2.Text = ""
For i = 0 To 9
Text2.Text = Text2.Text & Temp(i) & vbCrLf
Next
End Sub
Private Sub Form_Load()
Text1.Text = ""
Text2.Text = ""
End Sub
1.设置两个下标变量K1,K2表示最大值域最小值元素的下标
2. 初态：若a[0]>a[9]，则k1=0;k2=9;否则k1=1,k2=0;
3.循环：扫描数组余下的元素
令
max=a[0](若a[0]>a[9])若大于a[0]就赋值给max，切k1=i;输出i;a[i]与a[0]交换
min=a[9](若a[0]>a[9])若小于a[0]就赋值给min，切k2=j;a[j]与a[9]交换

VB程序设计~
Dim a, b, c, d, e, f, g, h, i As Integer
Private Sub rmbCound(ByVal rmb As Double)
a = Int(rmb / 100)
b = Int((rmb - a * 100) / 50)
c = Int((rmb - a * 100 - b * 50) / 10)
d = Int((rmb - a * 100 - b * 50 - c * 10) / 5)
e = Int((rmb - a * 100 - b * 50 - c * 10 - d * 5) / 1)
f = Int((rmb - a * 100 - b * 50 - c * 10 - d * 5 - e * 1) / 0.5)
g = Int((rmb - a * 100 - b * 50 - c * 10 - d * 5 - e * 1 - f * 0.5) / 0.1)
h = Int((rmb - a * 100 - b * 50 - c * 10 - d * 5 - e * 1 - f * 0.5 - g * 0.1) / 0.05)
i = (rmb - a * 100 - b * 50 - c * 10 - d * 5 - e * 1 - f * 0.5 - g * 0.1 - h * 0.05) / 0.01
End Sub
Private Sub Text1_KeyDown(KeyCode As Integer, Shift As Integer)
If KeyCode = 13 And IsNumeric(Text1.Text) Then
Call rmbCound(Val(Text1.Text))
Print "100元[" & a & "]张 " & _
"50元[" & b & "]张 " & _
"10元[" & c & "]张 " & _
"5元[" & d & "]张 " & _
"1元[" & e & "]张 " & _
"5角[" & f & "]张 " & _
"1角[" & g & "]张 " & _

这里主要考察的是 Sin 和 Cos 这两个函数的应用，假设文本框名称为 Text1，要显示结果的标签儿名称为 Label1，那么求正弦值的关键代码为：
Label1.Caption = CStr(Sin(Text1.Text))求余弦值的关键代码为：
Label1.Caption = CStr(Cos(Text1.Text))
完整代码需要再加 If 判断语句、CommandButton_Click() 事件等，把这些组织起来就是一个小程序了。
