計算機程式及實習 課堂作業之口頭報告 題目：商店結帳系統 南台科技大學 機械工程系 奈米一乙 學號： 學生：李昀叡

商店結帳系統說明： 在右方框裡輸入餐點數量，之後選擇打折數 點選試算後即可得知總金額 點選清除則可清除方框內數量

表單設計：設置輸出入介面 表單標題 Label1 Label7 Label2 Label3 Label4 Label5 RadioButton1 Button1 TextBox1 TextBox2 TextBox3 TextBox4 RadioButton3 Button2 Label6

執行程式 1. 輸入餐點數 量 2. 選擇所需打 折數 3. 執行試算按 鈕 4. 執行清除按 鈕

選點九折試算後結果點選八折試算後結果

心得 以前從未碰過 Visual Basic2008 這個東西 但是學了之後覺得很好玩，只是有些地方 還是很難，複雜的地方就努力和同學討論， 我們也能做一些簡單的程式，讓我們學了 不少東西，很充實很有趣。 Visual Basic2008 真是個不錯東西 !!
