C++ CODE

GradStudents are Students but they have the additional data member of researchArea.

Your program will loop asking for one of three options (add, print, or quit).

Add user option: You will create (using new) a Student object or a GradStudent object and add its pointer to the vector classMembers.

Print user option: You will print the entire class last, using the appropriate ToStr member function. You should NOT test whether a particular pointer in the class list points to a Student or a GradStudent. The correct ToStr function will be called automatically if you have properly defined functions for ToStr. \\

CODE!!

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

class Student {
public:
   Student(string initialName = \"No Name\") {
       name = initialName;
   }

   // Enter definition for a virtual ToStr member function here.

protected:
   string name;
};

class GradStudent : public Student {
public:
   // Enter definition for a paramteriezed contructor function here that sets both data members.

   // Enter definition for a virtual ToStr member function here.

private:
   string researchArea;
};

int main() {
   string usrOption;
   string inpName;
   string inpResearch;
   vector<Student*> classMembers;

   do {
       cout << \"Option: \";
       cin >> usrOption;
       cout << endl;
       if (usrOption == \"print\") {
           // Enter code here to print each member pointed to from classMembers using their respective ToStr member functions.
           }
       }

       else if (usrOption == \"add\") {
           cout << \"Name: \";
           cin >> inpName;
           cout << endl;
           cout << \"If grad student enter a one word research area, else enter \\\"NO\\\": \";
           cin >> inpResearch;
           cout << endl;
           if (inpResearch == \"NO\") {
               // Enter code here to create new objects (using new) for either a Student or a GradStudent
               // and add the pointer to the classMember vector.
           }
       }
   } while (usrOption != \"quit\");
   return 0;
}

Option add Name: Mary If grad student enter a one word research area, else enter \"NO\" MachineLearning Option add Name Bob If grad student enter a one word research area else enter NO NO Option print Mary is a graduate student researching the area of MachineLearning. Bob is an undergraduate student. Option quit
