【单选题】有如下事件过程： Sub () Show Dim Arr() As Arr = Array(1, 3, 5, 7, 9, 11, 13, 15) Call (Arr) For i = 0 To 7 Print arr(i); Next iEnd Sub 以上程序的功能是，通过调用过程，将数组Arr中的元素逆序存放并输出…

A.

Sub (dim a() as ) Dim T For i = (A) To (A) T = a(i) a(i) = a((A) – i) a((A) – i) = T Next i End Sub

B.

Sub (dim a() as ) Dim T Dim J As J = ((A) + (A)) / 2 For i = (A) To J T = a(i) a(i) = a((A) – i) a((A) – i) = T Next i End Sub

C.

Sub (a() As ) Dim T For i = (A) To (A) T = a(i) a(i) = a((A) – i) a((A) – i) = T Next i End Sub

D.

Sub (a() As ) Dim T Dim J As J = Int(((A) + (A)) / 2) For i = (A) To J T = a(i) a(i) = a((A) – i) a((A) – i) = T Next i End Sub
