Q2: Class student contains roll number, name and course as data members and Input_student and display_student as member functions. Create a class exam and publicly inherit it from student class. The derived class contains an array of marks and no_of_subjects as data members, and input_marks and display_result as member functions. Overload “<=”, “()” and “+=” operators and use the overloaded operators in the main function. Create an array of objects of the exam class and display the result of 5 students.
Write a C++ class to represent an Employee. Each employee is given a name, an age, a NIC number, anaddress, and a salary. Furthermore: The Employee class should keep track of how many employees (objects) have been created inthe system. Your Employee class should initialize all of its fields via a constructor.  Create function prototypes to set and get an employee's zip code. Declare a print_employee() function that prints all of an employee object's details.(Whenever possible, use constant functions.)
Write a C++ program which will perform the following operations: • Define a class with name Car and has the following members o Four private data members (Name, Model, Color and Price). . Define a constructor function (private member) which displays a text message whenever a new object is created successfully. . Define a destructor function (private member) which displays a text message whenever an object is deleted. o Define a method (public) which gets the data elements from user. . Define a method(public) which displays the data elements to user. o Create the objects of class Car and invoke its methods.

c++ Implement a MyInt class. An object in the MyInt class must be able to hold a single dynamically allocated integer. MyInt should have the following members: A member variable ptr of type int *.A parameterized constructor that takes nums of type int as input parameters.A destructor.A superimposed assignment operator (). The copy must be deep.A function set that sets the value of the number.A function get that returns the value of the number.The members must be encapsulated in accordance with the convention. Memory leaks must be avoided. To test your class, create objects and call functions according to the comments below. All tests must be validated.
