2．创建student类，在main函数中输入3个学生数据，包括学号，姓名和成绩，要求只输出成绩在80~90分数段的学生数据。 具体要求如下： （1）数据成员设定成private （2）成员函数设定成public （3）将类声明和成员函数的定义分开，放到.h和.cpp中

student.h文件：

#ifndef STUDENT_H
#define STUDENT_H

#include <string>

class Student {
public:
    Student(int id, std::string name, float score);

    int getId() const;
    std::string getName() const;
    float getScore() const;

private:
    int id_;
    std::string name_;
    float score_;
};

#endif // STUDENT_H

student.cpp文件：

#include "student.h"

Student::Student(int id, std::string name, float score)
    : id_(id), name_(name), score_(score) {}

int Student::getId() const {
    return id_;
}

std::string Student::getName() const {
    return name_;
}

float Student::getScore() const {
    return score_;
}

main.cpp文件：

#include <iostream>
#include <vector>
#include "student.h"

int main() {
    std::vector<Student> students = {
        Student(1, "Tom", 90),
        Student(2, "Jerry", 85),
        Student(3, "Alice", 75),
    };

    for (const auto& student : students) {
        float score = student.getScore();
        if (score >= 80 && score <= 90) {
            std::cout << "id: " << student.getId()
                      << ", name: " << student.getName()
                      << ", score: " << score << std::endl;
        }
    }

    return 0;
}
