The code provided implements a class Person with subtypes Teacher and Student. Student's have an id number, we don't bother tracking anything else. Main creates an array of pointers to various people and then calls checkStudent on each one. Write the function void checkStudent(Person* p). It should use dynamic_cast to test to see if the pointer actually points to a student. If so, print out the id number of the student followed by a newline. Otherwise print out "Not student" and a newline.

Code:

#include using namespace std;

class Person { public: virtual void foo() {} //Force Person to be polymorphic };

class Teacher : public Person { };

class Student : public Person { public: Student(int idNum) { id = idNum; } int getNum() { return id; } private: int id; };

//YOUR_CODE_ABOVE //Do not modify anything on or below the line above this

int main() { Person* people[6] = { new Person(), new Student(1), new Teacher(), new Student(3), new Student(2), new Teacher() };

for(int i = 0; i < 6; i++) { checkStudent(people[i]); }

}
