练习题一参考答案1.3.1 单项选择题1.3.2 多项选择题1.3.3 分析判断题1.3.4 程序设计题【习题1-49】编写一个华氏温度F 与摄氏温度C 之间转换的应用程序，界面如图1-4所示。

其中F 与C 之间的关系为：3259+=C F 。

参考程序如下：Private Sub Command1_Click() Dim f As Single, c As Single f = V al(Text1.Text) c = (f - 32) * 5 / 9 Text2.Text = Str(C) End SubPrivate Sub Command2_Click() Dim f As Single, c As Single c = V al(Text2.Text) f = 9 / 5 * c + 32 Text1.Text = Str(f)End Sub【习题1-50】编程将弧度值转换为角度值（度、分、秒）的形式，然后在窗体上显示出来。

程序运行界面如图1-5所示。

【提示】利用InputBox()输入弧度值，首先把弧度值转换为原始角度值，然后取整得到角度值，再把原始角度值减去度值，将结果转化为分值，采用类似思维即可求出结果。

参考程序如下：Private Sub Form_Click()Dim s As Single, a As Integer, b As Integer, c As Integer Const pi As Single = 3.14159图1-4 华氏温度与摄氏温度的转换图1-5 弧度值转换为角度值s = V al(InputBox("请输入弧度值:")) s1 = s s = s * 180 / pi a = Int(s) s = s - a s = s * 60 b = Int(s) s = s - bc = s * 60Print "输入的弧度值" & s1; "对应的角度值为:" Print a & "度" & b & "分" & c & "秒。
