学生成绩管理系统c语言代码供参考

1、C程序学生治理体系以下是用c说话编写的学生成绩治理体系的简略代码，可以用vc运行（供参考）#include stdio.h#include stdlib.h#include string.htypedefstruct student / 界说学生char name10;int number;char sex2;int math;int eglish;int clanguge;int average; student;typedefstruct unit / 界说接/电student date;struct unit * next; unit;unit * build() /树立链表并返回指针(

2、unit *p;if (p =(unit *)malloc( sizeof (unit) =NULL) printf(=初始化掉败！);return 0;else p- next =NULL;p- date . number=0; /头结点存下学生人数 printf(初始化成功！ n);return p;void add(unit * head) / 增长学生unit *p, *q;int m,n =0;q=head- next;p=(unit *)malloc( sizeof (unit);printf(=请输入新生姓名！n);gets(p - date . name);fflush(std

12、=q- next;p=p- next;q- next =p- next;p- next =q;else(p=p- next;q =q- next;break ;printf(=排序成功！ n);return 1;void menu()主菜单*、);删除学保printf( ttt1.新建体系 t2.添加学生 nttt3.生V4.检讨信息nttt5, 分列次序t6.读守信息nttt7.管信息t8.退出体系n);printf(=请选择你的操纵！n);)int save(unit * head) / 保管(FILE *fp;unit *p;p =head;if (fp =fopen( 学生，wb+)
