标题C++大作业你还烦恼吗？图书管理系统让你得到老师欣慰的目光…
C++图书管理系统
1.图书信息类
2.安全类。
3.菜单类
#include <iostream>
#include"Book_Manage.h"
#include"Safe_Mange.h"
#include"Menu_Manage.h"
using namespace std;
/**
* 我在主函数，声明了三个全局变量的类的类型;
* 以便于以后的调用;
*/
Book_Manage_Function BMF;
Safe_Mange_Function SMF;
Menu_Manage MM;
int main()
{
int N=0;
U_B_S* head_safe=SMF.Create_head();//创建安全系统的表头;
B_I* head_book=BMF.Createlist();//创建图书信息得头链表；
BMF.Login(head_book);
SMF.Load_All_ID(head_safe);
while(1)
{
MM.Menu_Login();
N=MM.Control_Login(head_safe);
if(N!=0){break;}
system("cls");
}
while(1)
{
MM.Menu_Initial();
MM.Control_Initial(head_safe,head_book);
system("cls");
}
return 0;
}
这是Book_Manage.h

/**
* 书籍管理系统

* 2.然后创建图书类，将其包含进去，
* 3.再创一个类分别声明以及实现 增.删.改.查.功能待加.回主菜单一系列函数；
* 直接就在类下面实现。
