Private Sub Command1_Click() Dim abc(3, 3) As Integer Dim abcMax As Integer Dim abcMin As Integer Dim i As Integer Dim j As Integer Dim iMax As Integer Dim jMax As Integer Dim iMin As Integer Dim jMin As Integer Dim abcSum As I...

Private Sub Command1_Click()Dim A(4, 4)'数组赋值Print "交换前:"For i = 1 To 4For j = 1 To 4A(i, j) = (i - 1) * 4 + j'数组显示Print A(i, j),NextPrintNext'交换数组的第二列和第四列For j = 1 To 4t = A(2, j)A(2, j) = A(4, j)A(4, j)...

Dim a(2, 3) As Integer Dim i As Integer Dim j As Integer Dim Sum As Long Dim Avg As Double For i = 0 To 2 For j = 0 To 3 Randomize a(i, j) = Int(Rnd * 65536) - 32768 Print a(i, j); If j = 3 Then Print Sum = Sum + a(i, j) Next N...

VB中只能这样: Dim A() As Variant 初始使用的时候这样: ReDim A(4, 10) 中途要改变下标而又想保留原数据则这样: ReDim Preserve A(4, 20) 注意只能改变最后一维的下标,则就是为什么我要把4放到前面的原因。

可能是3行4列,也可能是2行3列。 有Option Base 1语句,是后一种情况, 没Option Base 1语句,是前一种情况。

Dim a(5, 5) Private Sub Command1_Click() Text1 = "" Randomize For i = 1 To 5 For j = 1 To 5 a(i, j) = Int(Rnd * 90) + 10 Text1 = Text1 & a(i, j) & " " Next Text1 = Text1 & vbCrLf Next End Sub Private Sub Command2_Click() For i ...

Private Sub Command1_Click() Dim a() As Integer m = InputBox("请输入行数m:") n = InputBox("请输入列数n:") ReDim a(m, n) For i = 1 To m For j = 1 To n a(i, j) = InputBox("请输入a(" & i & "," & j & ")") Print a(i, j); Next j Prin...

'调整一下form大小,不然有些打印是看不见的 Option Explicit Private Sub Command1_Click() Dim i As Integer, j As Integer, arr(1 To 4, 1 To 5) As Long, av As Long For i = 1 To 4 For j = 1 To 5 Randomize arr(i, j) = Int(Rnd * 1000 +...
