Dim A B C As intEgEr

你的代码没问题,但你缺少 显示结果 的代码 代码如下 Private Sub Command1_Click() Label1.Caption = "" Dim a, b, c As Integer 'a = Text1.Text: b = Text2.Text 'val 是将 字符 转化为 数值的函数 因为 你定义abc 三个变量都是 整型 以防万...

刚才研究了一下上图中这种写法,在VB6中做了个实验: Private Sub Command1_Click() Dim a, b, c As Integer a = 100 / 3 b = 100 / 3 c = 100 / 3 Debug.Print a Debug.Print b Debug.Print c End Sub 结果打印出: 33.3333333333333 33.333333...

有区别。 第一种定义(dim a ,b,c as integer)结果,只有 C 是integer,其他两个是混杂类型,就是什么都能存。 第二种定义(dim a as integer,b as integer,c as integer),a b c 都是 integer

定义整型a b a=1 b=2 然后 赋值a=b=2 然后b=a=2 输出2 2 选D

Private Sub Command1_Click() Dim a As Integer Dim b As String Dim c As String a = 93 b = Left(a, 1) c = Right(a, 1) & b a = Val(c) Print a End Sub 这里用了2个字符串函数 Left 和 Right。

只有c为整形,a(),b()为变体类型,如果想都定义为整形,请用下面的语句: dim a() as integer,b() as integer,c as integer

声明变量类型 也可以这样写: Private Sub Command1_Click() Dim a,b,c,x,y as integer ……………… End Sub

不一样 Dim a As Single, b As Single, c As Single 三个变量都是 single类型 Dim a, b, c As Single 只有c是single,ab是变体类型和 Dim a,b Dim c as Signle一样 Dim a, b, c As Single MsgBox TypeName(a) & ";" & TypeName(a) & ";" & TypeN...

在VB中用如下方法限定变量类型 $ string 字符类型 % integer 整型 & long 长整型 # double 双精度浮点型 ! single 单精度浮点型 Step1 表示每次循环之后就给循环变量 + 1

Private Sub Command2_Click() Print "Command2:" f = 0 a = Val(InputBox("a=")): ff (a) b = Val(InputBox("b=")): ff (b) c = Val(InputBox("c=")): ff (c) Print Trim(a); "!+"; Trim(b); "!+"; Trim(c); "!="; f End Sub Private Sub ff(n ...
