[VB6 ] 兩個重複結構(Loop)的問題
(1)請問重覆結構(Loop) Num=Num+A+B與 B=B-3之程式碼會被執行幾遍？
Dim A as integer
Dim B as integer
Dim Num as long
A=36
Num=0
Do While A >=0
B=27
DO While B >=0
Num=Num+A+B
B=B-3
Loop
If A>=18 Then
A=A-2
Else
A=A-1
End If
Loop
我同學寫 (1) [(36-18)/2 + 1 +(16+1)]*10 = 270 次
但我在算的時候 [(36-18)/2 + 1 +(16+1)]*11 = 385 次
差在B的部分 當A=36 B=27 NUM=0
=24
=21
.
.
.
.
.
=3
=0
差在這裡 =-3 為什麼-3不用算進去呢?
=34 =27
.
.

我同學提早畢業了
所以不能問她~"~
幫我解答一下 謝謝~~!!!
