前言

又是一年一度的一期一會XD
從2021年開始，這是第三度參加了。第一年是挑戰leetcode連續刷題一個月(Leetcode刷題筆記)，因為工作主要使用的是C++，選擇用刷題來增加C++的基本語法熟悉度；第二年想開始學軟體設計，所以就選擇看設計模式(設計模式探索)。今年想要再去熟習C++語法的使用，所以又選了一本早該讀的C++經典：《Effective C++- 55 Specific Ways to Improve Your Programs and Designs》，顧名思義就是列了55點C++使用上可以注意的地方，希望看完可以更了解C++的運作，也寫出更好(更有效率、易於擴展及維護)的程式。

目標

這本書有幾頁我不確定，因為這次是買電子書XD
書名/ 版本：Effective C++- 55 Specific Ways to Improve Your Programs and Designs (third edition)
很明確這本書有55條準則，暫定一天一則按部就班的看，寫到哪裡算哪裡，但工作虐我千百遍，不能保證這30天的進度...打算邊讀邊紀錄思考筆記，混雜不專業的個人心得。
這次沒有去年的豪情壯志，立志要深入學習設計模式，提升程式的品質，只是想補充一下C++的相關知識，以免程式越寫越爛...

目錄

放個目錄在這邊，完成了再回來補上連結XD

結語

不多廢話，希望至少這30天下班躺平之餘可以持續閱讀 QQ
