  1. Dim C As Single Dim S As Single Let C = 2 * Pi * r Let S = Pi * r * r

  2. 赋值号 圆周长变量 表达式 Let C = 2 * Pi * r

  3. 有一个变量i，初始值为0，每次给它加1，共加5次，用赋值语句如何表示？有一个变量i，初始值为0，每次给它加1，共加5次，用赋值语句如何表示？ i = i + 1

  4. [Let] 变量 = 表达式 读作：将表达式的值赋给变量

  5. Private Sub Form_Click() Dim x As Single, y As Single Form1.Print -61; -34 Form1.Print 9 * 2; 12 Form1.Print "This is"; "a book" x = 3: y = 4 Print "x="; x, "y="; y End Sub

  6. 输出语句格式： [对象].Print [表达式列表][{；|，}]

  7. Private Sub Form_Click() Dim a As Integer, b As Integer, c As Integer Dim str As String Let a = 54 Let b = 114 c = a + b str = "Hello World" Print "a="; a, "b="; b, "c="; c Print str End Sub
