图书管理系统 C**实现的 包括B树 可以参考一下呀 有需要联系我哈

#include "head.h"
void main()
{
	BTree T;
	int order=0,booknum;
	char returndate[10],librarynum[10];
	Result result;
	InitBTree(T);
	printf("\n************************************************************************\n");
	printf("Welcome to the library system!\n");
	
	while(order!=6)
	{
		printf("\n************************************************************************\n");
		printf("请选择服务： 1.采编入库  2.清除库存   3.借阅  4.归还  5.显示  6.退出.\n");
		scanf("%d",&order);
		switch(order)
		{
			case 1:
				Procurement(T);
				PrintBTree(T);
				break;
			case 2:
				printf("请输入要删除的书的编号。\n");
				scanf("%d",&booknum);
				DeleteBook(T,booknum);
				PrintBTree(T);
				break;
			case 3:
