Consider the following Base class UniStudent: class UniStudent { protected: float getGPA() { return st_gpa; } string name; string major; private: int st_id; float st_gpa; public: Unistudent () ; Unistudent (string n, string m, int id, float gpa); void setStudentID (int id) ; void setGPA(float gpa) ; virtual bool isUnderGrad () = 0; virtual void PrintStudent() { cout < "Student ID: " << endl; } }; Write the class MScStudent in the answer box according to the following requirements: 1. class MScStudent must publicly inherit class UniStudent. 2. class MScStudent must have an additional string data member named thesisTitle 3. Define a constructor that will receive parameters for all data members in the base class and the derived class, your constructor should: o invoke the parametrized constructor in the base class appropriately o initialize the derived class data member 4. Override the function isUnderGrad to return the boolean value false. 5. Override the function PrintStudent to print all base class and derived class data members in the following order: thesisTitle, st_id, st_gpa, name and maior

Override the function PrintStudent to print all base class and derived class data members in the following order: thesisTitle, st_id, st_gpa, name and maior
5. Override the function PrintStudent to print all base class and derived class data members in the following order: thesisTitle, st_id, st_gpa, name, and major 6. Assume you have defined the function string getStudentRating() in class MScStudent. Furthermore, assume you have the following declaration in the main function: Unistudent * mPtr = new MScStudent ("Improving DNS Security", "Amal", "CS", 6666, 79.4) ; (a) Briefly describe what is the problem with the following function call cout <« mPtr->getStudentRating (); (b) what can you add in the blank at the end of the base class to make this function call valid? I Answers to requirements 1 to 5: Answer to Question 6: (a) (b)
