在VB中,使用变量前一般应对变量进行定义。以下变量定义语句错误的是()。
A: Dim x As Integer
B: Dim x As Integer,y As Single
C: Var x,y:Integer
D: Dim x As Integer,y As Integer
A: Dim x As Integer
B: Dim x As Integer,y As Single
C: Var x,y:Integer
D: Dim x As Integer,y As Integer
举一反三
- 下面可以正确定义2个整形变量和一个字符型变量的语句是() A: Dim x%, y As Integer, n As String B: Dim x As Integer, y, n As String C: Dim x, y As Integer, n As String D: Dim x%, y$, n As String
- 假定有一个模块,在其中定义一个公共变量,正确的是________。 A: Dim x as Integer B: Public Dim x as Integer C: Dim Public x as Integer D: Public x as Integer
- Sub s1(ByVal x As Integer, ByVal y As Integer) Dim t As Integer t = x: x = y: y = t End Sub Sub s2(x As Integer, y As Integer) Dim t As Integer t = x: x = y: y = t End Sub 则以下说法中正确的是( )。
- 下面哪个定义了一个整型变量x A: Dim x As Single B: Dim x As Integer
- 下面可以正确定义2个整型变量和1个字符串变量的语句是【 】 A: Dim n,m As Integer,s As String B: Dim a%,b$,c As String C: Dim a As Integer,b,c As String D: Dim x%,y As Integer,z As Suing
