Create a constructor for the Student class you created. The constructor should initialize each Student’s ID number to 9999, his or her points earned to 12, and credit hours to 3 (resulting in a grade point average of 4.0). Write a program that demonstrates that the constructor works by instantiating an object and displaying the initial values. Save the application as ShowStudent2.java.

- Objects and Pointers Write code to instantiate/create two Bicycle objects: a default object (my_bike) and a non-default object (sister_bike). For the non-default object you may hard-code (or make up) the required parameters (brand, price and wheel size). No console input is needed.arrow_forwardWhen you instantiate an object from a class, you give a name to this particular object so that your program can distinguish it from other objects you instantiate from the same class.

Get the object's donation count and store it in a variable called num_donations. Get the average donations from the object and store it in a variable called avg_donations. int main() { std::cout << "Number of donations: " << num_donations << "\n"; std::cout << "Average donation: $" << avg_donations << "\n"; return 0; }arrow_forward

- Readme.md: Stars(C++) This lab exercise will practice creating objects with constructors and destructors and demonstrate when constructors and destructors are called. Star Class Create a class, Star. A Star object has two member variables: its name, and a solar radius. This class should have a constructor which takes a std::string, the name of the star, and a double, the solar radius of the star. In the constructor, the Star class should print to the terminal that the star was born. For example, if you create a Star as follows: Star my_star("Saiph", 22.2); Then the constructor should print: The star Saiph was born. In the destructor, the Star class should print to the terminal that the star was destroyed, along with the number of times the volume of the sun that that star was, formatted to two decimal places. Hint: use the following line to set the precision to 2 decimal places: std::cout << std::fixed << std::setprecision(2); For example, when my_star above has its…arrow_forwardIf the contents of an object cannot be changed once the object is created, the object is called mutable object abstract object mutable object Encapsulationarrow_forwardThis has to be done in visual studio, c# windows form application (.net fromework). Question: The application should be able to do the following :• Create a class called Person which contains 4 private fields : Name(string), Surname (string),Course(string), CRNumber(int).• The class must contain 4 public properties which will be used to get and set the values of the private fields.• The class must contain a default constructer. The class must also contain an overloaded constructer which should be able to set the values of each of the private fields.• The class must contain a static ViewInfo method which will be used to display information of a queue of person objects back to the user neatly grouped underneath each other as displayed above.• Once a user clicks on the “Add Person” button then the information in the respective textboxes should be used to create a Person object (using the properties or the overloaded constructor) and add it to a queue which is of type Person.

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.arrow_forwardUsing C# programming language (using Microsoft Visual Studio), create a class called Personthat has some properties (e.g., name, surname, age etc.).
