C++中实现多态时怎样判断一个父类指针指向哪一个子类对象？

C++中实现多态时怎样判断一个父类指针指向哪一个子类对象？
就像Java中Instanceof()方法，我用typeid做不出来

#include "Person.h"
#include "Student.h"
#include <iostream>
#include <typeinfo>
using namespace std;

int main()
{
    Person* p = new Student(1, "小李", MALE, 21, 3, 1);
    p->print();
    if(typeid(p) == typeid(Student))
    {
        cout << "Yes" << endl;
    }
    else
    {
        cout << "No" << endl;
        cout << typeid(new Student(1, "小李", MALE, 21, 3, 1)).name() << endl;
    }
    delete p;

    return 0;
}
