关于#运算符#的问题，如何解决？

#include<iostream>
#include<string>
using namespace std;

class Person//基类
{
public:
    Person() = default;
    Person(string nam, int ag):name(nam),age(ag)//带参构造函数
    {
        cout << "基类已创建" << endl;
    }
    void PersonOut()
    {
        cout << "姓名:" << name << endl;
        cout << "年龄:" << age << endl;
    }
    ~Person() = default;
protected:
    string name;
    int age = 0;
};

class Student :public Person//派生类
{
public:
    Student() = default;
    Student(string nam, int ag, string cla, int ID) :Person(nam, ag), id(ID), classid(cla)//带参构造函数
    {
        cout << "派生已创建" << endl;
    }

    void StudentOut()
    {
        cout << "学生姓名:" << name << endl;
        cout << "学生年龄:" << age << endl;
        cout << "学生班级:" << classid << endl;
        cout << "学生ID:" << id << endl;
    }
protected:
    int id = 0;
    string classid;
};

int main()
{
    Student stu(" 张三 "，21，" 20测一 ",01);
    ///stu.PersonOut();
    stu.StudentOut();
    return 0;
}

Student类的构造方法没赋值，然后你创建对象的时候逗号打成中文字符了，帮你改好了，希望采纳支持一下博主
