学生图书馆管理系统c++

好的，学生图书馆管理系统可以分为以下几个功能模块：

1. 图书管理模块：包括图书的添加、删除、修改、查询和借阅等功能。

2. 学生管理模块：包括学生信息的添加、删除、修改和查询等功能。

3. 借阅管理模块：包括借阅记录的添加、删除、修改和查询等功能。

4. 统计分析模块：包括对图书的分类统计、借阅情况的统计分析等功能。

下面是一个简单的学生图书馆管理系统的C++代码实现，供参考：

#include <iostream>
#include <string>
#include <vector>
#include <algorithm>

    delete book1;
    delete book2;

    delete student1;
    delete student2;

    return 0;
}

该程序实现了图书馆管理系统的基本功能，包括添加图书和学生、借阅和归还图书、查询借阅记录等。程序的执行结果如下：

All books:
The Great Gatsby by F. Scott Fitzgerald
To Kill a Mockingbird by Harper Lee
1984 by George Orwell
All students:
Alice
Bob
Book borrowed successfully
Book borrowed successfully
Book is already borrowed
All books:
The Great Gatsby by F. Scott Fitzgerald (borrowed)
To Kill a Mockingbird by Harper Lee (borrowed)
1984 by George Orwell
Borrowed books:
The Great Gatsby by F. Scott Fitzgerald
1984 by George Orwell
Borrowed books:
To Kill a Mockingbird by Harper Lee
All books:
The Great Gatsby by F. Scott Fitzgerald
1984 by George Orwell
Borrowed books:
