用VB实现猜商品价格游戏程序。

Private Sub Command1_Click()
Randomize Timer
Dim jg As Integer, c As Integer, n As Integer
jg = Int(Rnd * 1001)
Do
n = Val(InputBox("请输入商品价格0~1000："))
c = c + 1
Select Case n
Case -1
Case Is > jg
MsgBox "高了,放弃请输入-1"
Case Is < jg
MsgBox "低了,放弃请输入-1"
End Select
Loop While jg <> n And n <> -1

If n = -1 Then
MsgBox "已经放弃"
Else
MsgBox "价格是：" & jg & "，猜的次数：" & c
End If

End Sub

'在窗体上画一个按钮，名称可用默认值“Command1”，Caption属性设为“开始”，复制以下代码：
private sub Command1_Click()
dim R as long
dim S as long ,sInput as string
dim sPrompt as string
dim iTimes as long
randomize timer
R=clng(rnd()*1000) '若不包括0和1000，须改成R=1+int(rnd()*999)
do
iTimes=iTimes+1
sInput=inputbox(sPrompt & "请输入第" & iTimes & "次所猜的价格：")
if isnumeric(sInput) then
S=val(sInput)
if S>R then sPrompt="‘" & S & "元’高了，"
if S if S=R then msgbox "‘" & S & "元’猜对了！！成绩为" & iTimes & "次！",vbInformation :exit sub
else
msgbox "您放弃了游戏，正确价格应该是：" & R & "元" :exit sub
end if
loop
end sub
