1 流程圖 if 流程 X>10 Raptor Raptor flow chart 1 if else 流程 x>y Raptor flow chart 2

2 練習寫一個程式, 輸入西元年份 yy, 輸出該年是否閏年 yy is divisible by 400 yy is divisible by 4 but (not divisible by 100) Raptor flow chart 3 Switch Case 概念 mm... Raptor flow chart 4

3 switch 流程 mm=1 days = 31 break mm=2 days = 28 break default 練習 : 處理整數成績 Raptor flow chart 5 for 流程 i=0 i<10 i++ 練習 : 計算 1 到 100 的偶數和 Raptor flow chart 6

4 while 流程 i=0 i<10 i++ Raptor flow chart 7 do while 流程 i=0 i++ i<10 Raptor flow chart 8

5 關於迴圈 (Loops) 迴圈之基本要素控制變數初值設定檢驗條件控制變數改變三種迴圈敘述之不同常見錯誤 Off by one ( 少一次 ) 無窮迴圈迴圈與執行效率練習寫一程式, 要求使用者不斷輸入及 Echo 學生成績, 直到輸入為負時為止印出學生總人數及平均成績 Raptor flow chart 9 結構化程式 goto Raptor flow chart 10

6 虛擬 / 偽代碼 (Pseudo Code) 幫助思考程式流程沒有程式語言正式, 省略細節, 易寫易懂限定使用結構化程式流程控制, 容易以程式語言改寫較流程圖方便紙筆追蹤測試 (Tracing an algorithm) Raptor flow chart 11 Euclid 輾轉相除法輸入正整數 a & b 只要 ( b <> 0 ) { r = a b 後的餘數 ; a = b; b = r; } gcd = a; 測試數據 1: a=12, b=56 2: a=120, b=18 3: a=105, b=13 4: a=356, b=220 5: a=2136, b=3312 練習 : n <= limit Raptor flow chart 12

7 練習 : 判斷是否質數的篩檢法要判斷 x 是否質數, 可用 d (2... x), 逐一檢查是否能整除 x 如果都不能整除,x 便是質數, 否則 x 就不是質數函式 isprime(x) 印出 1 到 100 的所有質數 Raptor flow chart 13 Raptor: Flowchart programming 輸出 Adding block / symbols 變數 Raptor Flowchart 14

8 Enter an statement x 0 Raptor Flowchart 15 Create output symbol 輸入 scanf 輸出 printf 選擇 if, switch 廻路 for, while Raptor Flowchart 16
