Question
Person class, such that both Student and Faculty pointers can be stored in a single vector. Your Faculty class should have a string for the name of the faculty member, and a string for the department they belong to. Your class should also implement the toString function required by the Person class. Follow the same format as the Student toString function. When your program is run, you will be given 2 sets of 3 inputs which you should use to create the appropriate objects: a string representing the type ("student" or "faculty"), a string for the name of the person, and either a double GPA for a student, or a string representing a department for a faculty. Create pointers to the appropriate objects and store them both in a single vector called my_list.

Enter if if the type is student/faculty : student
Enter name : Kumar
Enter GPA : 2
Enter if if the type is student/faculty : faculty
Enter name : Kumar
Enter department name : cse
