数据库语言题:计算机随机的产生两位数的加减法算术题。人工输入8个数,将前4个数与后4个数对换?
- 人工输入8个数,将前4个数与后4个数对换。即第1个与第8个互换,第2个与第7个互换……。输出对换后的结果。用vpf编写程序
- 首先建立的窗体界面(如图来摆放控件位置),所有控件用默认值,然后去掉代码窗口所有代码,粘入以下代码即可:如果要源文件,可以留下邮箱,我发给你Option ExplicitDim He As LongDim OK1 As LongPrivate Sub Command1_Click() If List1.ListCount 0 Then List1.Clear End If Command3.Enabled = True Command1.Enabled = False Call ChuTi Text1.SetFocus OK1 = 0End SubPrivate Sub Command2_Click() OK1 = 0 Command3.Enabled = False Command1.Enabled = TrueEnd SubPrivate Sub Command3_Click() Call PanDuan Call ChuTiEnd SubPrivate Sub Form_Load() Randomize Timer Label1.Caption = "" Label2.Caption = "正确率:" Text1.Text = "" Command1.Caption = "开始答题" Command2.Caption = "结束答题" Command3.Enabled = False Command3.Caption = "下一题" Command3.Default = TrueEnd SubPrivate Sub ChuTi() Dim JiaShu1 As Long Dim JiaShu2 As Long Dim t As Long JiaShu1 = Rnd() * 89 + 10 JiaShu2 = Rnd() * 89 + 10 If Int(Rnd() * 100) Mod 2 0 Then He = JiaShu1 + JiaShu2 If He 99 Then Call ChuTi Exit Sub End If Label1.Caption = JiaShu1 & "+" & JiaShu2 & "=" He = JiaShu1 + JiaShu2 Else If JiaShu1 JiaShu2 Then t = JiaShu1: JiaShu1 = JiaShu2: JiaShu2 = t Label1.Caption = JiaShu1 & "-" & JiaShu2 & "=" He = JiaShu1 – JiaShu2 End IfEnd SubPrivate Sub PanDuan() Dim N As Long N = Val(Trim(Text1.Text)) If N = He Then List1.AddItem Label1.Caption & Text1.Text & " √" OK1 = OK1 + 1 Else List1.AddItem Label1.Caption & Text1.Text & " ×" End If Text1.Text = "" Text1.SetFocus Label2.Caption = "正确率:" & Int(OK1 / List1.ListCount * 10000) / 100 & "%"End SubPrivate Sub ChuTi() Dim JiaShu1 As Long Dim JiaShu2 As Long Dim t As Long JiaShu1 = Rnd() * 89 + 10 JiaShu2 = Rnd() * 89 + 10 If Int(Rnd() * 100) Mod 2 0 Then He = JiaShu1 + JiaShu2 If He 99 Then Call ChuTi Exit Sub End If Label1.Caption = JiaShu1 & "+" & JiaShu2 & "=" He = JiaShu1 + JiaShu2 Else If JiaShu1 JiaShu2 Then t = JiaShu1: JiaShu1 = JiaShu2: JiaShu2 = t Label1.Caption = JiaShu1 & "-" & JiaS
674减去最大的两位数,差是多少
- 575
有些两位数,加48,变成三位数;减48,变成一位数,这样的两位数有几个
- 52 53 54 55 56 57六个
123 678组成两位数相减为35,需要四组数据,所用数字不能重复!
- 小学一年级数学题!问题补充: 组成两个两位数相减!
- 67-32 71-36 72-37 73-38
减数是89被减数是最大的两位数 差是多少
- 被减数:99差:99-89=10行家正解,你参考下
197减两位数还等于两位数
- 再把任意选择的数减去这个和,等于8所以十位和各位数相等这个数是88
100减两位数,由于个位、十位都是0,所以要向什么借
- 100减两位数,由于个位、十位都是0,所以要向上一位借一。
用4,5,6,7,9四个数运用到两位数减两位数等于一位数
- 很简单啊74-65=9
有一个两位数,这个数的十位数是3,这个数减6.差的十位上仍是3.这个数减7.差的+位上是2。想一想
- 有一个两位数窢长促短讵的存痊担花,这个数的十位数是3,这个数减6.差的十位上仍是3.这个数减7.差的+位上是2。想一想这个数是多少?
- 这个数减6,不用向高位借1,减7就要向高位借1。因此这个数的个位数字是6又已知这个数是两位数,十位数字是3因窢长促短讵的存痊担花此这个数是36
两位数相加为99相减为45
- 最大的两位数是99大于90的最小质数是97这两个数是(99+97)÷2=98(99-97)÷2=1
