Question

高分求c++图书管理系统，要求看补充。。采纳后追加80分。

图书管理系统
1对于同一作者同意书名的书，存储书名、书目编号、作者名、库存册数（不包括已借出的）、已借出册数。
2对于每一本书还要存储一个登录号（这是区别每一本书的唯一标识）、当前借阅该书的读者姓名与借书证号，借阅日期。
系统功能如下：
1创建存储系统。
2增加新书。
3删去无使用价值的旧书。
4借书处理。要求读者提供书目号和登录号，一读者限借2册，检查库中有无读者要求借阅的图书，检查该读者已借阅图书的数量。

我的这个完全符合你的要求！ 把分给我吧，CSU的！！

Answer 2

这个是我以前做课程设计时的图书馆管理系统，自己做的没问题，你自己小改一下就可以了。
#include<iostream>
#include<string>
using namespace std;

private:
string bookname;
double price;
unsigned number;
public:
void borrow();
void restore();
void display();
Book(unsigned number=20);
void setsize(string bookname,double price);
};

Book::Book(unsigned number)
{
this->number=number;
}

void Book::setsize(string bookname,double price)
{
this->bookname=bookname;
this->price=price;
}

void Book::display()
{
cout<<"您借的书名为："<<" "<<bookname<<endl;
cout<<"此书价钱为："<<" "<<price<<"元"<<endl;
}

void Book::borrow()
{
cout<<"当前共有图书："<<number<<"本"<<" ";
cout<<"您借走1本，还剩："<<(number-1)<<"本"<<endl;
}

void Book::restore()
{
cout<<"当前共有图书："<<number<<"本"<<" ";
cout<<"您归还1本后共"<<(number+1)<<"本"<<endl;
}

void main()
{
Book mybook;
string x;
cout<<"借书输入borrow还书输入restore"<<endl;
cin>>x;

if(x=="borrow")
{
string bookname;
double price;

cout<<"请输入书名和价钱： "<<endl;
cin>>bookname>>price;

mybook.setsize(bookname,price);
mybook.display();

cout<<"当前图书馆的图书情况： ";
mybook.borrow();
cout<<endl;
}

if(x=="restore")
{
string bookname;
double price;

cout<<"请输入书名和价钱： "<<endl;

}

}
