有如下事件程序，运行该程序后输出结果是_________。 Private Sub Command33_Click() Dim x As Integer, y As Integer x=1:y=0 Do Until y＜=25 y=y+x*x x=x+1 Loop MsgBox "x=" & x &",y=" & y End Sub A: x=1，y=0 B: x=4，y=25 C: x=5，y=30 D: 输出其他结果

已知齐次方程$(x-1){{y}^{''}}-x{{y}^{'}}+y=0$的通解为$Y={{C}_{1}}x+{{C}_{2}}{{e}^{x}}$，则方程$(x-1){{y}^{''}}-x{{y}^{'}}+y={{(x-1)}^{2}}$的通解是( ) A: ${{\text{C}}_{1}}x+{{\text{C}}_{2}}{{e}^{x}}-({{x}^{2}}+1)$ B: ${{\text{C}}_{1}}x+{{\text{C}}_{2}}{{e}^{x}}-({{x}^{3}}+1)$ C: ${{\text{C}}_{1}}x+{{\text{C}}_{2}}{{e}^{x}}-{{x}^{2}}$ D: ${{\text{C}}_{1}}x+{{\text{C}}_{2}}{{e}^{x}}-{{x}^{2}}+1$

编写如下程序： Private Sub Command1_Click() Dim x As Integer, y As Integer x = 1: y = 1 Do y = x * y If y > 10 Then Print x, y Exit Do Else x = x + 3 End If Loop While x <= 10 End Sub 运行程序，输出结果为______

完成以下功能：计算分段函数完成程序。 x2+1 (x<0) y= 2x+1 (0≤x<1) 3x3 (x≥1) Private Sub Command1_Click() Dim y As Single, x As Single x = InputBox("请输入x的值") If x（） Then y = x * x + 1 （） x < 1 Then y = 2 * x + 1 Else y = 3 * x ^ 3 End If Print x; y End Sub

运行下面的程序，第二行显示结果是___________。 Private Sub Form_Click() Dim A As Integer Dim i As Integer A = 5 For i = 1 To 9 Call sub1(i, A) Print i, A Next i End Sub Private Sub sub1(x As Integer, y As Integer) Static N As Integer Dim I As Integer For I = 3 To 1 Step -1 N = N + x x = x + 2 Next I y = y + N End Sub
