Step by step
Solved in 2 steps
- Mark the following statements as true or false. The member variables of a class must be of the same type. (1) The member functions of a class must be public. (2) A class can have more than one constructor. (5) A class can have more than one destructor. (5) Both constructors and destructors can have parameters. (5)What do you call the technique that inserts an object to a function that can replicate the behavior of the object instead of merging objects with different classes? A. Polymorphism with an Object B. Abstraction C. Inheritance D. Encapsulation___________ is an Object-Oriented programming feature that allows you to define new classes from existing classes. 1 Overriding 2 Overloading 3 Inheritance 4 Polymorphism
- The pillar that allows you to build a specialized version of a general class, but violates encapsulation principles is ______________.A c++ a program in which class A is base class for class B. While Class C is derived from class B and class D is derived from class E. Provide explicit implementation of default constructors and destructors. Write a test program which initializes each class object and shows execution order of constructor and destructor by printing appropriate messages. Note: Solve as soon as possible use OOP ConceptsA(n) _______________class is based on another class, and inherits characteristicsfrom it.
- Design a class named Person with properties for holding a person’s name, address, and telephone number. Next, design a class named Customer, which is derived from the Person class. The Customer class should have a property for a customer number and a Boolean property indicating whether the customer wishes to be on a mailing list. Demonstrate an object of the Customer class in a simple application.The ability to create classes with more specific attributes and methods that share the properties and methods of existing classes is referred to as: Abstraction Polymorphism Typecasting InheritanceWhen a class can be derived from another class and use its methods, this is called Polymorphism. A. True B. False
- People in School Objective: At the end of the activity, the students should be able to: Create a program that exhibits inheritance. Procedure: Write a simple information system that will store and display the complete information of a student, faculty, or employee. Create four (4) no-modifier classes named Person, Student, Faculty, and Employee. Create a public class named CollegeList. This class shall contain the main method. Refer to the UML Class Diagram for the names of the variables and methods. The (-) symbol represents private variables, while (+) represents public method. This should be the sequence of the program upon execution: Prompt the user to select among Employee, Faculty, or Student, by pressing E, F, or S. Ask the user to type the name and contact For Employee, ask the user to type the employee's monthly salary and the department where he/she belongs to (Ex. Registrar). Then, display name, contact number, salary, and For Faculty, ask the user to press Y if…Code required in C sharp Part 1: Design a class named Person with properties for holding a person’s name, address,and telephone number. Next, design a class named Customer, which is derived fromthe Person class. The Customer class should have a property for a customer numberand a Boolean property indicating whether the customer wishes to be on a mailinglist. Demonstrate an object of the Customer class in a simple application. Part 2 A retail store has a preferred customer plan where customers can earn discounts onall their purchases. The amount of a customer’s discount is determined by theamount of the customer’s cumulative purchases in the store as follows:• When a preferred customer spends $500, he or she gets a 5 percent discount onall future purchases.• When a preferred customer spends $1,000, he or she gets a 6 percent discounton all future purchases.• When a preferred customer spends $1,500, he or she gets a 7 percent discounton all future purchases.• When a preferred customer…1) Abstraction means showing only the essential information and hiding the details true or false 2) Modes of Inheritance Options: a) Public, protected, private b) Public, object, private c) Public, object, main
