B. 求VB編程:貨幣兌換,輸入人民幣,兌換成美元,比例1:8.25
有的地方沒說清楚
大概寫了下

Text1.Text = 8.25 * CDbl(Text1.Text)
End If
If Option2.Value = True Then
Label1.Caption = "港幣幣種"
Text1.Text = 1.15 * CDbl(Text1.Text)
End If
End Sub
Private Sub Command3_Click()
Text1.SetFocus
Text1.SelLength = (Text1)
End Sub
Private Sub Form_Load()

C. 70分求VB用一元人民幣兌換成1分,2分,和5分硬幣,共有多少種不同的兌換方法
拖一個按鈕 粘貼下面代碼就可以了
Private Sub Command1_Click()
Dim i As Integer
Dim j As Integer
Dim k As Integer
Dim x As Integer
Print "1分", "2分", "5分"
For i = 1 To 100
For j = 2 To 100 Step 2
For k = 5 To 100 Step 5
If i + j + k = 100 Then
Print i, j, k
x = x + 1
End If
Next k
Next j
Next i
Me.Caption = "共" & x & "種"
End Sub
D. vb 將100元換成10元,5元和1元的組合,一共多少種組合方法
這是每種錢幣至少一張時的換法,如允許為0,可將1改為0(共3處)
PrivateSubCommand1_Click()
List1.AddItem"10元5元1元"
Fora=1To19
Forb=1To(100-10*a-1)5
c=100-10*a-5*b
List1.AddItem""&a&""&b&""&c
n=n+1
Nextb
Nexta
List1.AddItem"共"&n&"種"
EndSub
E. 換零錢問題。將一元錢換成1分,2分,或5分的零錢有多少換法。vb編程
思路:
1元最多換100個1分,50個2分和20個5分的
代碼:
Private Sub Command1_Click()
Dim I As Integer, J As Integer, K As Integer, SUM As Single, N As Integer
For I = 0 To 100
For J = 0 To 50
For K = 0 To 20
SUM = I * 0.01 + J * 0.02 + K * 0.05
If SUM = 1 Then
List1.AddItem "1分" & I & "個;2分" & J & "個;5分" & K & "個"
N = N + 1
End If
Next K
Next J
Next I
MsgBox "共" & N & "種換法"
End Sub
如果是每次換都必須有3種硬幣,那就要將上面代碼中的FOR循環從1開始循環
分別是541和461種換法
F. 1人民幣能兌換多少柬埔寨幣
柬埔寨現行貨幣的單位是瑞爾(RIEL),現行的貨幣有一百、二百、五百、一千、二千、五千、一萬、二萬、五萬、十萬瑞爾等十種紙幣,但二萬瑞爾以上的貨幣極少見,硬幣幾乎不使用。

EndSub
PrivateSubCommand3_Click()
Text3.Text=""

H. VBusdt我以15塊錢一個的價錢買進,現在跌到了3塊,請問我還有多少錢
如果是這種情況的話,那麼你就要看你是購買了多少個,如果你只購買了10個的話,那麼現在來講的話,你還有的錢數就應該是10×3=30。因為你現在來講的話,所剩的錢應該是以這個單價乘以數量來進行計算的,而不是依照你購買時候的價格來進行計算的,因為你現在的價格已經跌到了三塊錢,那麼你就只能以三塊錢的價格進行出售。
I. 怎麼用VB計算把一元整錢換成零錢有幾種演算法
共4562種取法。程序如下:
Private Sub Command1_Click()
Dim A1 As Integer, A2 As Integer, A5 As Integer, A10 As Integer, A20 As Integer, A50 As Integer, S As Integer
Dim R As String, N As Long
For A1 = 0 To 100
For A2 = 0 To 50
For A5 = 0 To 20
For A10 = 0 To 10
For A20 = 0 To 5
For A50 = 0 To 2
S = A1 + 2 * A2 + 5 * A5 + 10 * A10 + 20 * A20 + 50 * A50
If S = 100 Then
If A1 <> 0 Then R = R + "一分" + Str(A1) + "個,"
If A2 <> 0 Then R = R + "二分" + Str(A2) + "個,"
If A5 <> 0 Then R = R + "五分" + Str(A5) + "個,"
If A10 <> 0 Then R = R + "一毛" + Str(A10) + "個,"
If A20 <> 0 Then R = R + "兩毛" + Str(A20) + "個,"
If A50 <> 0 Then R = R + "五毛" + Str(A50) + "個,"
R = Left(R, Len(R) - 1) + "。"
Debug.Print R
N = N + 1
R = ""
End If
Next: Next: Next: Next: Next: Next
Debug.Print "共"; N; "種取法。"
End Sub
你也可以把結果輸出到文件中。
