雙向鍊錶 基於C語言

最近複習了c語言的相關知識，實現了資料結構裡面的雙向鍊錶。

下面是main.c檔案：

#include

"duallinklist.h"
#include
intmain()
printf
("開始列印鍊錶：\n");
i =0;
for(
duallinklistmove
(list,
duallinklistlength
(list)-1
);!duallinklistend
(list)
;duallinklistpre
(list)
, i++
)duallinklistdelete
(list,0,
null);
duallinklistdelete
(list,0,
null);
printf
("此時雙向鍊錶長度為：%d\n"
,duallinklistlength
(list));
printf
("刪除狀態：%d\n"
,duallinklistdelete
(list,1,
null))
;printf
("此時雙向鍊錶長度為：%d\n"
,duallinklistlength
(list));
list =
duallinklistdestroy
(list);}
return0;
}
