具体学生一卡通管理系统

好的，下面我为您提供一份基于C++的学生一卡通管理系统的代码示例，希望能对您有所帮助。

#include <iostream>
#include <vector>
#include <string>
#include <ctime>

using namespace std;

// 学生类
class Student {
private:
    string name; // 姓名
    int id; // 学号
    string department; // 学院
public:
    Student(string name, int id, string department) {
        this->name = name;
        this->id = id;
        this->department = department;
    }

    string getName() {
        return name;
    }

    int getId() {
        return id;
    }

    string getDepartment() {
        return department;
    }

    void setName(string name) {
        this->name = name;
    }

    void setId(int id) {
        this->id = id;
    }

    void setDepartment(string department) {
        this->department = department;
    }
};

// 一卡通类

    vector<Record> records; // 消费记录

    }

    vector<Record> getRecords() {

// 消费记录类

    int amount; // 消费金额
    string time; // 消费时间
public:

};

// 主函数

    // 初始化学生一卡通管理系统
    StudentCardSystem system;
    Student student1("张三", 1001, "计算机科学与技术");
    Student student2("李四", 1002, "软件工程");
    system.addStudent(student1);
    system.addStudent(student2);

    // 查询消费记录
    vector<Record> records1 = system.getRecords(10001);

    cout << "消费记录：" << endl;
    cout << "卡号\t消费金额\t消费时间" << endl;
    for (int i = 0; i < records1.size(); i++) {

    }
    for (int i = 0; i < records2.size(); i++) {
        cout << records2[i].getCardId() << "\t" << records2[i].getAmount() << "\t" << records2[i].getTime() << endl;
    }

    return 0;
}

以上代码仅供参考，具体实现还需根据实际需求进行调整。
