CS实现学生成绩管理系统代码

根据提供的引用内容，有两种语言可以实现学生成绩管理系统，分别是C++和Java。下面我将为你介绍这两种语言的实现方式。

1. C++实现学生成绩管理系统代码：

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

using namespace std;

// 学生类
class Student {
private:
    string name;
    int score;

public:
    Student(string name, int score) {
        this->name = name;
        this->score = score;
    }

    string getName() {
        return name;
    }

    int getScore() {
        return score;
    }
};

// 学生成绩管理系统类
class GradeManagementSystem {
private:
    vector<Student> students;

public:
    void addStudent(string name, int score) {
        Student student(name, score);
        students.push_back(student);
    }

    void displayAllStudents() {
        for (int i = 0; i < students.size(); i++) {
            cout << "Name: " << students[i].getName() << ", Score: " << students[i].getScore() << endl;
        }
    }
};

int main() {
    GradeManagementSystem system;
    system.addStudent("Alice", 90);
    system.addStudent("Bob", 80);
    system.addStudent("Charlie", 70);
    system.displayAllStudents();

    return 0;
}

2. Java实现学生成绩管理系统代码：

import java.util.ArrayList;
import java.util.List;

// 学生类
class Student {
    private String name;
    private int score;

    public Student(String name, int score) {
        this.name = name;
        this.score = score;
    }

    public String getName() {
        return name;
    }

    public int getScore() {
        return score;
    }
}

// 学生成绩管理系统类
class GradeManagementSystem {
    private List<Student> students;

    public GradeManagementSystem() {
        students = new ArrayList<>();
    }

    public void addStudent(String name, int score) {
        Student student = new Student(name, score);
        students.add(student);
    }

    public void displayAllStudents() {
        for (Student student : students) {
            System.out.println("Name: " + student.getName() + ", Score: " + student.getScore());
        }
    }
}

public class Main {
    public static void main(String[] args) {
        GradeManagementSystem system = new GradeManagementSystem();
        system.addStudent("Alice", 90);
        system.addStudent("Bob", 80);
        system.addStudent("Charlie", 70);
        system.displayAllStudents();
    }
}
