这个是成绩管理系统，可行？不过都差不多，档案c档课程设计这东西很简单的20秒视频源码

学生成绩管理系统用C语言结构体去写要求显示学生成绩管理，学生档案管理，查询和统计

跟你的要求差不多，但是mac nginx 源码安装有点小差别，自己改改吧！

#include <stdio.h>

#include <string.h>

#include <stdlib.h>

#define NAME_MAX //书的名字的最长字数

#define WRITER_MAX //作者名字的最长

#define PUB_MAX //出版单位最长名字

#define TIME //出版时间

typedef struct books

{

int loading;

char name[NAME_MAX];

char writer[WRITER_MAX];

int identify;

char pub[PUB_MAX];

char time[TIME];

int price;

struct books * next;

}book;

//头结点不存储信息

void Init(book * head)

{

head->next=NULL;

}

//打印一些欢迎词之类的。。。。。

void welcome()
