c加加学生管理系统代码

C++学生管理系统是一个常见的编程习项目，用于管理学生信息的录入、查询、修改和删除等。以下是一个简单的C++学生管理系统代码示例：

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

using namespace std;

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

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

    string getName() {
        return name;
    }

    int getAge() {
        return age;
    }

    string getId() {
        return id;
    }
};

// 学生管理系统类
classManagementSystem {
private:
    vector<Student> students;

public:
    void addStudent(Student student) {
        students.push_back(student);
    }

    void displayAllStudents() {
        for (int i = 0; i < students.size(); i++) {
            cout << "Name: " << students[i].getName() << endl;
            cout << "Age: " << students[i].getAge() << endl;
            cout << "ID: " << students[i].getId() << endl;
            cout << endl;
        }
    }

    void searchStudent(string id) {
        for (int i = 0; i < students.size(); i++) {
            if (students[i].getId() == id) {
                cout << "Name: " << students[i].getName() << endl;
                cout << "Age: " << students[i].getAge() << endl;
                cout << "ID: " << students[i].getId() << endl;
                return;
            }
        }
        cout << "Student not found." << endl;
    }

    void deleteStudent(string id) {
        for (int i = 0; i < students.size(); i++) {
            if (students[i].getId() == id) {
                students.erase(students.begin() + i);
                cout << "Student deleted." << endl;
                return;
            }
        }
        cout << "Student not found." << endl;
    }
};

int main() {
    StudentManagementSystem system;

    // 添加学生
    Student student1("Alice", 18, "1001");
    Student student2("Bob", 19, "1002");
    system.addStudent(student1);
    system.addStudent(student2);

    // 显示所有学生
    system.displayAllStudents();

    // 查询学生
    system.searchStudent("1001");

    // 删除学生
    system.deleteStudent("1002");

    return 0;
}

这段代码实现了一个简单的学生管理系统，包括添加学生、显示所有学生、查询学生和删除学生等功能。你可以根据自己的需求进行扩展和修改。
