[单项选择题] 有如下函数过程: Function lj(x As Integer) As Long Dim s As Long Dim i As Integer s=0 For i = 1 T

[单项选择题] 有如下函数过程:
Function lj(x As Integer) As Long
Dim s As Long
Dim i As Integer
s=0
For i = 1 To x
s=s+ i
Next i
1j= s
End Function
在窗体上添加一个命令按钮，名为Command1, 编写事件过程调用该函数：
Private Sub Command1 Click()
Dim i As Integer
Dim sum As Long
For i = 1 To 5
sum = sum + 1j(i)
Next i
Print sum
End Sub
