第C語言單鏈表實(shí)現(xiàn)學(xué)生管理系統(tǒng)本文實(shí)例為大家分享了C語言單鏈表實(shí)現(xiàn)學(xué)生管理系統(tǒng)的具體代碼，供大家參考，具體內(nèi)容如下

代碼：

#includestdio.h

#includestdlib.h

#includestring.h

#includemalloc.h

structStudent

intnum;//學(xué)號(hào)

charname[20];//名字

charsex[2];

intage;

structStudent*next;

voidinsert(structStudent**head);//插入

voidprint(structStudent*head);//遍歷所有鏈表

voiddele(structStudent**head);//刪除指定內(nèi)容

voidmodify(structStudent**head);//修改內(nèi)容

voidfind(structStudent*head);//查找學(xué)生信息

intmodify_menu();

intmain()

structStudent*head=NULL;
