vb利用隨機函式rnd生成10個10-99的整數,並計算其中的素數個數。(求大神看看**錯了?)
4樓:用著追她
1、首先bai,我們
給主函式du先定一個函式。
2、然zhi後dao我們編寫
版for迴圈語句。
3、然後我們編寫輸權出語句及範圍。
4、然後我們開始執行測試。
5、這句警告沒關係,如果不想看到可以新增呼叫數學函式。
6、這時我們便可以看到效果了。
5樓:匿名使用者
我給你優化了一下,由於最大99,所以只需要判斷到9就可以了,一回旦j=10,則為素數答
private sub command1_click()randomize
dim i as integer, j as integer, n as integer, nl as integer, st as integer
for i = 1 to 10
n = int(rnd * 90 + 10)st = st & n & " "
for j = 2 to 9
if n mod j = 0 then exit fornext j
if j = 10 then
nl = nl + 1
end if
next i
text1.text = st
text2.text = nl
end sub
6樓:聽不清啊
已經copy改好了:
private sub command1_click()randomize
dim i as integer, j as integer, n as integer, nl as integer, st as string
for i = 1 to 10
n = int(rnd * 99 + 10)st = st & n & " "
for j = 2 to n - 1
if n mod j = 0 then exit fornext j
if j = n then
nl = nl + 1
end if
next i
text1.text = st
text2.text = nl
end sub
7樓:匿名使用者
n = int(rnd * 90 + 10)

下面是我給你寫的程式,需要新增四個文字框,三個按鈕,兩個標籤,其中文字框text1和text2的multiline屬性設定成true,scrollbars屬性可以設定成2或者不用設定。你要是對程式有什麼疑問也可以留個qq,我把工程和窗體檔案發給你。

有一點瑕疵,生成兩位數的地方有點錯誤,判斷有無重複數的地方也有點錯誤,而且可以進行簡化。修改了的地方我做了註釋。(貼上過來時出錯了,我重新貼上了下)
