1樓:聽不清啊

private sub ***mand1_click()randomize

dim a as long, b as long, n as integer

a = rnd * 1000 + 1

do while true

b = rev(a)

if b = a or n = 7 then exit doprint a; "+"; b; "="; a + ba = a + b

n = n + 1

loop

print

end sub

function rev(byval x)while x > 0

y = y * 10 + x mod 10x = x \ 10

wend

rev = y

end function

求vb大佬看看這哥問題如何解決 謝謝!!

public function jiecheng(byval n as integer) as integer

dim jc as integer = 1

for i = 1 to n

jc = jc * i

next

return jc

end function

public function jiecheng(byval n as integer) as double

dim jc as double

jc = 1

for i = 1 to n

jc = jc * i

next

jiecheng = jc

end function

private function factorial1(intn as integer) as integer

'採用遞迴計算階乘

if intn = 0 then

factorial1 = 1

else

factorial1 = factorial1(intn - 1) * intn

end if

end function

給你幾個階乘的函式,你可以直接呼叫階乘的函式去做哦

option explicit

private sub ***mand1_click()

dim m as double, n as double

inputdata m, "m"

inputdata n, "n"

if m < n then

print "***bination(" & m & "," & n; ")=" & 0

else

print "***bination(" & m & "," & n; ")=" & factorial(m) / (factorial(n) * factorial(m - n))

end if

end sub

public sub inputdata(byref t, byval char as string)

t = inputbox(char + "=", "輸入框", 25)

if int(val(t)) <> val(t) or val(t) < 0 then

msgbox "資料錯誤!

請重新輸入:", 16

inputdata t, char

end if

end sub

public function factorial(byval r)

dim i as integer

factorial = 1

for i = 1 to r

factorial = factorial * i

next i

end function

求vb大佬看看!!謝謝!!**怎麼寫!!

4樓:匿名使用者

本程式使用了控制項陣列:

**:private type student

stu_id as string

name as string

*** as string

politicalorientation(1) as string

end type

private sub ***mand1_click()

dim stud as student

with stud

.stu_id = text1.text

.name = text2.text

for i = 0 to 1

if option1(i).value then .*** = option1(i).caption

if check1(i).value then

.politicalorientation(i) = check1(i).caption

else

.politicalorientation(i) = "非" + check1(i).caption

end if

next i

picture1.print "學號:" + .stu_id

picture1.print "姓名:" + .name

picture1.print "性別:" + .***

picture1.print "政治面貌1:" + .politicalorientation(0)

picture1.print "政治面貌2:" + .politicalorientation(1)

picture1.print

write #1, .stu_id; .name; .***, .politicalorientation(0); .politicalorientation(1)

close #1

end with

end sub

執行效果:

可以實現的哈,戳頭像取數字要答案

追加寫檔案

dim s as string

dim filename as stringfilename = shuxiang & xingzuo & ".txt"

open filename for input as #1do while not eof(1)

line input #1, s

print s

loop

close #1

7樓:聽不清啊

private sub ***mand1_click()

dim m as integer, n as integer

m = inputbox("請輸入矩陣的行數:")

n = inputbox("請輸入矩陣的列數:")

dim a(20, 20) as integer

m1 = 1: n1 = 1: m2 = 1: n2 = 1

randomize

for i = 1 to m

for j = 1 to n

a(i, j) = rnd * 90 + 10

print a(i, j);

if a(i, j) > a(m1, n1) then m1 = i: n1 = j

if a(i, j) < a(m2, n2) then m2 = i: n2 = j

next j

print

next i

print

print "最大值: a(" & m1 & "," & n1 & ")=" & a(m1, n1)

print "最小值: a(" & m2 & "," & n2 & ")=" & a(m2, n2)
