Write a program to create a base class: “Question3”, with protected data member: x (int) and with pure virtual function: “Task ()” [Returns no value and takes no argument]. Create a derived class of “Question3” such as “Sub1” (Derive features in public mode). In sub1, there is a member function in public section: get_data1 () to take input for x, and define Task () in this class to display the factorial of x. [Implement the above program by creating pointer to base in main () function and call the necessary functions]. Write the program in c++ language.

PROGRAMMING LANGUAGE: C++   Write a program that has a base class named FlightCrew. This class shouldhave three data members: an integer to store the ID of the crew member, aninteger to store the number of years of service and another integer to storethe total salary of the member. Provide a parameterized constructor in theclass to set the values of the data members.Derive a class Pilot from FlightCrew to contain two additional data members,an integer to store the number of hours of flight and a boolean to storewhether the Pilot has military experience or not. Provide a paramete rizedconstructor in the Pilot class. Provide a function bonus() in the class wherethe bonus of a pilot is his number of flight hours times the 10% of his salary.Likewise, provide a function isEligible() in the class to find out if the pilot iseligible for promotion or not. A pilot is eligible for promotion to the nextrank if he has at least 5 years of experience and the number of total flighthours is greater…

Write a C++ code that uses pure virtual functions in the base class universityperonnel. The universityperonnel class is an abstract class and no objects can be created for it. Your base class has two pure virtual functions getData() and isoutstanding(). Your parent class should also include two member functionsto input() and display() the name of personnel. Your code includes two derived classes, student and instructor respectively. The derived classes each contain a function called get () and outstanding(). get () function of Student class should input name of personnel and asks user to input GPA whereas outstanding function determines either the GPA>3 or not. Similarly, get () function of instructor class should input name of personnel and asks user to input no. of publications whereas Outstanding function determines either the no. of publications >50 or not. Student and instructor objects are casted into the person class type through array of pointers. Ask user first either he…

Create a base class named Point consisting of x and y data members representing point coordinates. From this class, derive a class named Circle with another data member named radius. For this derived class, the x and y data members represent a circle’s center coordinates. The member functions of the Point class should consist of a constructor, an area() function that returns 0, and a distance() function that returns the distance between two points,(x1,y1) and (x2,y2), where     Additionally, the derived class should have a constructor and an override function named area() (PI*pow(radius,2)) that returns a circle’s area.   Task: 1-Include the classes constructed in a working C++ program. 2-Have your program call all the member functions in each class. 3- In addition, call the base class’s distance() function with two circle objects and explain the results this function returns.
