Question

C语言程序设计的图书管理系统

要求：
使用“C”！！！！来编写

本设计以学校图书馆借阅系统为例，要求具有以下模块：
① 学生注册：工作人员通过计算机对学生进行信息注册，发放借书证；
② 图书浏览查询：学生们通过此模块来查询自己所需要的图书；
③ 读者借书：学生通过此模块来完成借阅图书；
④ 图书预约：学生通过此模块来完成预约图书；
⑤ 读者还书：学生通过此模块来完成退还图书；
⑥ 打印信息：图书管理人员通过此模块来完成打印学生信息的工作。

请在主函数

void main()
{

char op;
printf("欢迎试用图书管理系统\n");
printf("按1进入学生注册系统\n");
printf("按2进入图书查询系统\n");
printf("按3进入读者借书系统\n");
printf("按4进入图书预约\n");
printf("按5进入读者还书\n");
printf("按6打印信息\n");

printf("按0退出\n");

printf("请输入0--6，其他指令不可用。\n");

scanf("%d",&op);
switch(op)
{
case '1' : RegisterStudent();break;
/*case '2' : book_out();break;
case '3' : book_in();break;
case '3' : book_add();break;
case '4' : book_del();break;
case '0' : exit(0);break;*/
}

default : printf("没有对应的系统指令，请查证重输\n");break;

}
的基础上添加函数和结构体，请注明所引用源代码的来源地址...
邮箱274686588@qq.com，直接发上本帖也可以。
变量名我自己改。
能用的追加80分。
函数部分那里在修改阶段所以我用了注释- -
可以无视
