vB程序代码

1.数值型函数:abs(num): 返回绝对值 sgn(num): num>0 1; num=0 0; num<0 -1;判断数值正负 hex(num): 返回十六进制值 直接表示:&Hxx 最大8位 oct(num): 返回八进制值 直接表示:&Oxx 最大8位 sqr(num): 返回平方根 num>0 int(num):

★条件判断语句条件判断控制最主要的概念在于条件表达式的功能.相关的流程控制语句,会依据所给定的测试数据,对程序部分片段作选择性的执行操作.在VB中提供了IfThen与Select Case两种条件判断语句.IfThen判断语句If..Then判断

Private Sub Form_Load() Dim a(9) As Integer Dim i As Integer Dim sum As Integer Dim min As Integer Dim max As Integer Dim avg As Double sum = 0 Randomize a(0) = Int(Rnd

把20个单词定义成一个组,然后用 right(组(i),1)="D"确定是否满足条件.满足条件 个数+1

面积计算公式:计算公式s=(1/4)√(a+b+c)*(a+b-c)*(a+c-b)*(b+c-a)周长就是 三个相加了 这段代码你参考下,首先判断输入的三边长度是否合法,然后再计算Private Sub Command1_Click(Index As Integer)Dim s As SingleSe

整个简单点的,弄清楚里面函数的关系就可以了Private Sub Command1_Click() Text4.Text = "" If (Val(Text1.Text) + Val(Text2.Text) + Val(Text3.Text)) / 3 > 95 And UBound(Split(Text1.Text & Text2.Text & Text3.Text, "100")) > 1 Then Text4.Text = "一等奖" End Sub

Private Sub Command1_Click() s = Text1.Text For i = 1 To Len(s) If Mid(s, i, 1) >= "A" And Mid(s, i, 1)

1.form1.caption = "VB程序"2.x mod 5 = 0 or x mod 9 = 0 3.字母4.dim i as integer5.abs(x+y)6.int(rnd*50)+507.选择分支8.True9.CDEF10.33 或者34

这个不是for语句嵌套么?K循环每执行两次,J循环执行一次,J循环每执行三次,I循环执行一次.

由九个不同数字组成的等式 Private Sub Command1_Click() Dim Token(9) As Integer, I As Integer, K As Integer Dim Result As Integer, J As Integer For I = 1234 To 4987 Erase Token Token(0) = 1 For J = 1 To Len(CStr(I)) K = Val(Mid(CStr(I), J, 1))
