C 單向鍊錶

單向鍊錶 鍊錶的功能包括 向尾節點新增資料，遍歷鍊錶中的節點，在鍊錶結束時釋放所有節點 class cnode 定義乙個節點類 class csllist 定義鍊錶類csllist類 csllist m nodesum 0 pdelete null ptmp null m pheader null ...

C 單向鍊錶反轉

根據我的理解，我這裡用到用到三個指標 假設有如下鍊錶 新建三個指標，資訊分別如下 head curr都指向list，而 temp指向乙個空塊 然後將curr移動到下一塊鍊錶，這時將head next指向temp 最後移動temp到head，再將head移動到curr，整個過程大概就這樣 如下 nod...
