1.Option Explicit'题目:窗体上建立了一个文本框Text1("输入口令")和一个命令按钮Command1("检查")。判断密码是否正确,并显示相应提示;在加载窗体时设置密码框最大长度为8,密码显示字符为“*”
Private Sub Command1_Click()
x = Text1.Text
If x 【? ?】"12345678" Then (like 和 =,不定)
MsgBox ("欢迎你用机!")
El
MsgBox ("对不起,口令错")
End If
Text1.Text = ""
Text1.SetFocus

2.'题目:以下程序的功能如(图1)。
Private Sub Form_Click()
Dim a%, b%, c%, d!
Dim x1, x2
Dim p, q, r
a = InputBox("请输入a的值")
b = InputBox("请输入b的值")
c = InputBox("请输入c的值")
d = b * b - 4 * a * c
p = -b / (2 * a)
If d >= 0 Then
If 【 ? ? 】 Then (d>0)
r = Sqr(d) / (2 * a)
x1 = p + r
x2 = p - r
El
x1 = p
x2 = p
露出文 【? ?】 (end if)
Print "x1="; x1, "x2="; x2
【 ? ? 】 (el花胶鸡汤的做法)
q = Sqr(-d) / (2 * a)
Print "x1="; p; "+"; q; "i", "x2="; p; "-"; q; "i"
End If
End Sub
3.'下面过程max()用于求3个数中最大值,利用这个过程求5个数中最大值。
Private Sub Form_Click()
Print "5个数34、124、68、73、352的最大值是:"
max1 = max(34, 124, 68)
max1 = max(【?】) (max1, 73, 352)
Print max1
End Sub
Public Function max(ByVal a%, ByVal b%, ByVal c%)
If a > b Then
m = 【?】 (a草莓榨汁最佳搭配)
El
m = b
End If
If m 【? ?】Then (> c)
max = m
El
乘法的验算 max = c
End If
End Function
4.'下面的程序段用于求矩阵相乘C=A×B,设A、B、C分别为m×p、p×n、m×饱满的热情n的矩阵。

For k = 1 To p
sum = sum +【 ? ? 】
Next k
c(i, j) =【 ? ? 】
Next j, i
Print "输出矩阵"
For i = 1 To m
For k = 1 To n
Print c(i, k),
