- 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
- 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
- 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$, n As String
- 下面可以正确定义两个整型变量和—个字符串变量的语句是（）。 A: Dim n,m As Integer,s As String B: Dim a%,b$,c As String C: Dim a As Integer,b,c As String D: Dim x%,y As Integer,z As String
- 下面可以正确定义两个整型变量和一个字符串变量的语句是______。 A: A) Dim a%.b $,c As String B: B) Dim n,m As Integer,s As String C: C) Dim x As Integer,y%,z $ D: D) Dim a As Integer,b,c As String
