- Solve as C++ Code please: 1- Creates a class Student with 3 attributes: name, id and level. a. Add a constructor able to create a Student; b. Add the methods getId and getLevel; c. Add the method display able to display the attributes, 2- Creates a class StudentPhD extending the class Student with two more attributes: specialty and supervisorName; a. Add a constructor to create a StudentPhd b.

You are going to change the class you created in Program7 so that it has a constructor and some properties. In your GeoPoint class make the following changes (note your variable, parameter and method names may be different. Adjust as needed.): Add a constructor __init__(self, lat=0, lon=0,description = ‘TBD’) that will initialize the class variables __lat ,__lon and the __description. Notice that the constructor will also default lat and lon to zero and description to ‘TBD’ if they are not provided. Change the SetPoint method so that instead of individual coordinates SetPoint(self, lat, lon) it takes a single sequence. Add a property: Point = property(GetPoint,SetPoint). Make sure GetPoint and SetPoint are the names you used for the get and set methods you already wrote for points. Add another property: Description = property(GetDescription,…A car company makes a car produce application. There are diffrerent types of models that the company builds as sedan and sport.

- Q) Create three classes, first class should have all variables and all functions public, second class should have all variables private and all functions public it has a constructor to cofigure private variables, third class should have public and private functions it has a destructor to display a message "ALL DONE". NOTE: CREATE OBJECTS IN MAIN(), MANIPULATE PRIVATE VARIABLES THOUGH PUBLIC FUNCTIONS.Create an application named CarDemo that declares at least two Car objects and demonstrates how they can be incremented using an overloaded ++ operator. Create a Car class that contains a model and a value for miles per gallon. Include two overloaded constructors. One accepts parameters for the model and miles per gallon; the other accepts a model and sets the miles per gallon to 20. Overload a ++ operator that increases the miles per gallon value by 1. The CarDemo application creates at least one Car using each constructor and displays the Car values both before and after incrementation.Assume that you have created a class named MyClass.
