在窗体上画一个名称为Command1的命令按钮,然后编写如下事件过程：下面程序的输出结果是( )。 public class Sun { public static void main(String args[ ]) { int n=4 ,sum=0; while (n＞0) { sum+=n; n--; } System
以下各组选项中,均能正确定义二维实型数组a的选项是( )有如下程序： Private Sub Command1_Click() Dim a As Single Dim b As Single a=5:b=4 Call Sub1(a,b) End Sub Sub Sub1(x As Single,y As Single) t=X X=t\Y
Y处画一个点)： Dim cmdmave As Boolean Private Sub Form_MouseDown(Button As Integer,X As Single,Y As Single) If cmdmave Then Forml．PSet(X,Y) End lf End Sub Private Sub Form_MouseUp(Button As Integer,j
