  // In Task 2, we discussed multilevel inheritance with parameterized constructors for Student, UndergraduateStudent,  and  GraduateStudent  classes  in  a  university  management  system. Can  you  explain  the  advantages  of  using  multilevel  inheritance  with  specific   details  about the functions and data members in these classes? How were the parameterized constructors (e.g.,  setting  student  name,  age,  and  ID)  used  to  ensure  that  each   class  in  the  hierarchy correctly initializes its properties. #include < iostream > using namespace std ; class Student { private :     string name , ID ;     int age ; public :     Student () { name = "" , ID = "" , age = 0 ; }     Student ( string n , string i , int a ) { name ...

  // Construct a class stack with member functions isEmpty, isFull, push, pop. Then make a class Human with data members name, father name // and age. Then derive a class from it Student with data members rollNumber, department. Make a static count variable to check the // total number of students anytime without calling object. Overload ++ operator that will increase the age of student by one. // Your stack class should hold the record of every student.(array in stack class will be of student type) #include < iostream > using namespace std ; const int stackSize = 10 ; class Human { private :     string name , fatherName ;     int age ; public :     Human ( string n = "" , string f = "" , int a = 0 ) { name = n , fatherName = f , age = a ; }     void setName ( string n ) { name = n ; }     void setFather ( string f ) { fatherName = f ; }     void setAge ( int a ) { age = ...
