什麼是LFG?

LFG代表邏輯流圖,用於表示計算機硬體或軟體中的邏輯演算法。它是一種圖形流程圖,包含表示指令和條件的符號,以及顯示流程的箭頭。據說LFG可以幫助程式師快速設計解決難題的系統。

我為什麼要使用 LFG?

使用邏輯流圖或 LFG 可以幫助開發人員以更少的工作量和更少的重做來創建可靠、準確的代碼,從而提高程式設計效率。當程式使用 LFG 樣式的邏輯時,調試會更容易 - 因為可以通過流程圖跟蹤錯誤。可視化格式還使多人更容易在複雜的編碼項目上進行協作。

如何創建 LFG?

如果你有一些程式設計經驗,創建邏輯流圖相對簡單。首先確定您希望程式完成哪些操作,並在邏輯語句中定義它們。然後使用標準符號(有多個版本)以圖形的形式映射出每個語句,並以正確的順序將每個操作連結在一起。

LFG 與其他程式設計圖有什麼不同嗎?

與可用於類似目的的樹形圖或決策表相比,邏輯流圖是唯一的,因為它們是二維的,並且包含以易於解釋的方式直觀地連結在一起的特定符號。此外,在顯示複雜演算法時,LFG 往往比其他圖表具有更多的線條。

使用 LFG 時是否存在缺點或犧牲?

使用邏輯流圖時的一個重要考慮因素是它們很複雜,需要大量的程式設計經驗。錯誤通常涉及在 LFG 的多個頁面或部分手動跟蹤錯誤,如果您不知道程式如何工作,這很困難。另外,在創建良好的 LFG 之前,還有很多符號需要學習。

邏輯流程圖可以幫助調試軟體嗎?

邏輯流圖可以成為軟體開發中調試的有用工具。通過將程式分解為邏輯步驟並映射它們之間的數據流,可以更輕鬆地確定可能發生錯誤的位置。由於 LFG 提供了程式的高級檢視,因此它可以説明您在潛在問題發生之前識別它們。

使用 LFG 有哪些高級技巧?

使用邏輯流圖時,一個好的提示是記住在進行更改或更新后檢查操作之間的連結。它們需要驗證,否則程式可能會在運行時遇到錯誤。此外,請留意外部資訊源(如資料庫),在進行更新後可能需要進行其他測試。

使用 LFG 需要深厚的程式設計知識嗎?

一般來說,是的,儘管通過一些練習,您可以在短時間內相對熟悉 LFG。但在開始之前,您應該對所使用的程式設計語言有很好的瞭解,並了解用於表達 LFG 中資訊流的各種符號。

LFG 如何優於其他程式設計技術?

LFG 的主要優點是它能夠以開發人員可以理解的視覺清晰方式表示複雜的演算法,即使他們沒有説明您編寫 LFG。通過每個操作的標準化符號,編碼可以更快地進行。由於節點和箭頭清楚地顯示了程序的邏輯流程,因此您的 LFG 還可以説明查找錯誤。

如何開始創建邏輯流程圖?

LFG 的一些「入門」技巧包括從小處著手——從示例圖表開始,熟悉基礎知識。嘗試將任務分解為具有自己的節點和操作的小塊、可管理的部分。在每一步中查看您的邏輯,以便在以後導致更多問題之前發現錯誤。為節點、操作等使用有意義的標籤 - 它使其他人(包括可能正在執行您的設計的程式師)更容易閱讀圖形。
