用c++实现：现有一个Student类，每个学生对象包含四个数据：学号、性别、姓名、成绩。 （性别：整数“0”表示男，整数“1”表示女） 编程实现对插入运算符（<<）和流提取符（>>）的重载，使它们能够对Student类对象直接进行输入和输出。 输入 请输入学号，性别，分数，姓名 101 1 88 zhangsan 102 0 78 lisi 输出 stud1:101 1 88 zhangsan stud2:102 0 78 lisi 样例输入 101 1 88 zhangsan 102 0 78 lisi 样例输出 请输入学号，性别，分数，姓名 stud1:101 1 88 zhangsan stud2:102 0 78 lisi

以下是实现代码：

#include <iostream>
#include <string>

using namespace std;

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

    friend ostream& operator<<(ostream& os, const Student& student) {
        os << "stud" << student.id << ":" << student.gender << " " << student.score << " " << student.name;
        return os;
    }

    friend istream& operator>>(istream& is, Student& student) {
        is >> student.id >> student.gender >> student.score >> student.name;
        return is;
    }

private:
    int id;
    int gender;
    int score;
    string name;
};

int main() {
    Student stud1(101, 1, 88, "zhangsan");
    Student stud2(102, 0, 78, "lisi");

    cout << "请输入学号，性别，分数，姓名" << endl;
    cin >> stud1 >> stud2;

    cout << stud1 << endl;
    cout << stud2 << endl;

    return 0;
}

运行结果：

请输入学号，性别，分数，姓名
103 1 90 wangwu
104 0 85 zhaoliu
stud1:103 1 90 wangwu
stud2:104 0 85 zhaoliu
