【单选题】在窗体上画两个命令按钮,名称分别为Command1、Command2,并编写如下程序 Const n=5,m=4 Dim a(m,n) Private Sub Command1_Click() k=1 For i=1 To m Forj=1 To n a(i,j)=k k=k+1 Next j Next i End Sub Private Sub Command2_Click() summ=0 F...
【单选题】有如下程序: Const n = -5 Const m = 6 Dim a(n To m) As Integer For i = LBound(a, 1) To UBound(a, 1) a(i) = i Next i Print a(LBound(a, 1)); a(UBound(a, 1)) 运行后输出的结果为( )。
