OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
The __________ declares that this method overrides a method in the base class.
a. override keyword
b. class keyword
c. virtual keyword
d. base keyword

Step by step
Solved in 3 steps
- The __________ declares that a derived class is allowed to override a method. a. void keyword b. protected keyword c. base keyword d. virtual keywordT/F: Instance variables are shared by all the instances of the class. T/F: The scope of instance and static variables is the entire class. They can be declared anywhere inside a class. T/F: To declare static variables, constants, and methods, use the static modifier.This function is used to check whether an object is an instance of a specific class or a subclass of that class. a. isinstance b. isobject c. isreference d. _ _str_ _
- When implementing a method, use the class's accessor and mutator methods to access the class data. O static O public O private O protectedDynamic Games Instructions: Write a class called Game that contains a video game’s name, genre, and difficultyLevel. Include a default constructor and destructor for the class. The constructor should print out the following message: “Creating a new game”. The destructor should print out the following message: “In the Game destructor.” Include appropriate get/set functions for the class. In main(), prompt the user to enter the number of games he or she has played in the past year. Dynamically create a built-in array based on this number (not a vector or object of the array class) to hold pointers to Game objects. Construct a loop in main() that executes once for each of the number of games that the user indicated. Within this loop, ask the user to enter the name and genre of each game. Using a random number generator, generate a difficultyLevel between 1-10 (inclusive). Seed this random number generator with 100. Next, dynamically create a Game object (remember that this…A(n) __________ is a method that appears in a base class but expects to be overridden in a derived class. a. abstract method b. virtual method c. concrete method d. base method
- T/F A method defined in a class can access the class' instance data without needing to pass them as parameters or declare them as local variables.Python program for this project: Patient Charges Write a class named Patient that has attributes for the following data: First name, middle name, and last name Address, city, state, and ZIP code Phone number Name and phone number of emergency contact The Patient class’s _ _init_ _ method should accept an argument for each attribute. The Patient class should also have accessor and mutator methods for each attribute. Next, write a class named Procedure that represents a medical procedure that has been performed on a patient. The Procedure class should have attributes for the following data: Name of the procedure Date of the procedure Name of the practitioner who performed the procedure Charges for the procedure The Procedure class’s _ _init_ _ method should accept an argument for each attribute. The Procedure class should also have accessor and mutator methods for each attribute. Next, write a program that creates an instance of the Patient class, initialized with sample data. Then,…6. Patient Charges Write a class named Patient that has attributes for the following data: • First name, middle name, and last name • Address, city, state, and ZIP code • Phone number ● The Patient class's init__ method should accept an argument for each attribute. The Name and phone number of emergency contact Patient class should also have accessor and mutator methods for each attribute. Next, write a class named Procedure that represents a medical procedure that has been performed on a patient. The Procedure class should have attributes for the following data: • Name of the procedure • Date of the procedure • Name of the practitioner who performed the procedure • Charges for the procedure 107 The Procedure class's __init__ method should accept an argument for each attribute. The Procedure class should also have accessor and mutator methods for each attribute Next, write a program that creates an instance of the Patient class, initialized with sample data. Then, create three…
- Question - Create a class named Pizza with the following data fields: description - of type String price - of type double The description stores the type of pizza (such as sausage and onion). Include a constructor that requires arguments for both fields and a method named display to display the data. For example, if the description is 'sausage and onion' and the price is '14.99', the display method should output: sausage and onion pizza Price: $14.99 Create a subclass named DeliveryPizza that inherits from Pizza but adds the following data fields: deliveryFee - of type double address - of type String The description, price, and delivery address are required as arguments to the constructor. The delivery fee is $3 if the pizza ordered costs more than $15; otherwise it is $5. Code that is not accepted - class DeliveryPizza extends Pizza { private double deliveryFee; private String address; public DeliveryPizza(String desc, double price, double deliveryFee, String address){…Parent Class: Food Write a parent class called Food. A food is described by a name, the number of grams of sugar (as a whole number), and the number of grams of sodium (as a whole number). Core Class Components For the Food class, write: the complete class header the instance data variables a constructor that sets the instance data variables based on parameters getters and setters; use validity checking on the parameters where appropriate a toString method that returns a text representation of a Food object that includes all three characteristics of the food Class-Specific Method Write a method that calculates what percent of the daily recommended amount of sugar is contained in a food. The daily recommended amount might change, so the method takes in the daily allowance and then calculates the percentage. For example, let's say a food had 6 grams of sugar. If the daily allowance was 24 grams, the percent would be 0.25. For that same food, if the daily allowance was 36 grams, the…Car ClassWrite a class named Car that has the following fields:• yearModel. The yearModel field is an int that holds the car’s year model.• make. The make field references a String object that holds the make of the car.• speed. The speed field is an int that holds the car’s current speed. In addition, the class should have the following constructor and other methods.• Constructor. The constructor should accept the car’s year model and make as arguments. These values should be assigned to the object’s yearModel and make fields. The constructor should also assign 0 to the speed field.• Accessors. Appropriate accessor methods should get the values stored in an object’s yearModel, make, and speed fields.• accelerate. The accelerate method should add 5 to the speed field each time it is called.• brake. The brake method should subtract 5 from the speed field each time it is called.Demonstrate the class in a program that creates a Car object, and then calls the accelerate method five…
