C++实现学生请假系统

对于学生请假系统的实现，你可以使用++来完成。下面是一个简单的示例代码，用于演示学生请假系统的基本功能：

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

using namespace std;

// 学生类
class Student {
private:
    string name;
    int id;
public:
    Student(string name, int id) : name(name), id(id) {}

    string getName() const {
        return name;
    }

    int getId() const {
        return id;
    }
};

// 请假记录类
class LeaveRecord {
private:
    Student student;
    string reason;
public:
    LeaveRecord(Student student, string reason) : student(student), reason(reason) {}

    Student getStudent() const {
        return student;
    }

    string getReason() const {
        return reason;
    }
};

// 请假系统类
class LeaveSystem {
private:
    vector<LeaveRecord> leaveRecords;
public:
    void addLeaveRecord(LeaveRecord record) {
        leaveRecords.push_back(record);
        cout << "请假记录添加成功！" << endl;
    }

    void displayLeaveRecords() const {
        if (leaveRecords.empty()) {
            cout << "暂无请假记录" << endl;
        } else {
            for (const auto &record : leaveRecords) {
                cout << "学生姓名：" << record.getStudent().getName() << endl;
                cout << "学生学号：" << record.getStudent().getId() << endl;
                cout << "请假原因：" << record.getReason() << endl;
                cout << "-----------------------" << endl;
            }
        }
    }
};

int main() {
    LeaveSystem leaveSystem;

    // 添加请假记录
    Student student1("张三", 1001);
    LeaveRecord record1(student1, "身体不适");
    leaveSystem.addLeaveRecord(record1);

    Student student2("李四", 1002);
    LeaveRecord record2(student2, "家庭原因");
    leaveSystem.addLeaveRecord(record2);

    // 显示请假记录
    leaveSystem.displayLeaveRecords();

    return 0;
}

这段代码实现了一个简单的学生请假系统，包括学生类、请假记录类和请假系统类。你可以根据实际需求进行扩展和修改。
