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:
Consider the following statements:
class twoStory: protected house
{
...
};
a. In this declaration, which class is the base class and which class is the derived class.
b. What is the type of this inheritance?

What is the type of this inheritance?QUESTION 17 Which of the following are incorrect? (Choose all that apply) A. You may declare a final abstract class. B. The constructors in an abstract class should be protected. C. An abstract class contains constructors. OD. An interface may contain constructors. DE. The constructors in an abstract class are private.
- QUESTION 2 In object oriented programming, inheritance improves code readability and maintenance by allowing new classes to re-use existing classes. Use inheritance to solve the following problem: A: A Car is a Vehicle and has a name, a max_speed value and a number_of_cylinders attribute that specifies the number of cylinders in the car's engine. - Add accessor and mutator methods to get and set the values of the class attributes. - Attributes of the car objects are initialized at the time when the object is created. - When a car object is printed, its name, max_speed and number_of_cylinders are shown. B: An Airplane is also a Vehicle and has a name, a max_speed value and a number_of_engines attribute that specifies the number of jet engines the airplane has. - Add accessor and mutator methods to get and set the values of the class attributes. - Attributes of the airplane objects are initialized at the time when the object is created. - When an airplane object is printed, its name,…QUESTION 2 In object oriented programming, inheritance improves code readability and maintenance by allowing new classes to re-use existing classes.

Write a definition of a class and write a program that implements all the functionality of the class that has the following properties. The Main Program should invoke all functionality of this class, i.e., secretType. Input: from a file - the person's name and age and weight and height Output: The Original input and based on their BMI, their weight status. The name of the class is secretType. a. The class secretType has four member variables: name (a string), age and weight (int), height (double) b. The class secretType has the following member functions: (Make the accessor functions const) с. i. print – outputs the data in the member variables in a nicely formatted ii. setName - sets the name iii. setAge – sets the age iv. setWeight – sets the weight setHeight – sets the height V. vi. getName – value returning function returns the name vii. getAge – value returning function returns the age viii. getHeight – value returning function returns the height ix.…Problem Statement with Hints 1. Write classes to hold Account, SB - Account and Current - Account details. [Here implement the concept of inheritance.] The common properties of the account are Account number, name and amount. Specifics of SB account is 4% interest to be paid per month. Implement the run - time polymorphism by creating base class variable and derived class object. Ask the user for which type of accou nt to be created then create the corresponding account (Note: Use scanner class). Implement function overriding by having deposit and withdraw functions and perform the required action accordingly. Ensure base class can’t be instantiated. (Note: Abstract k eyword can be used). 2. Define the minimum balance for the both the type of accounts. Use final keyword to create constants. Ensure sb account class and current account class will cannot be used as base classes (Note: You can use final classes).
- Select the answer that best describes the following statements: 1. Usage of static variables inherently violates OOP. II. The private access modifier only allows classes within the same package to access the modified class, method, or attribute. Only statement I is true Only statement II is true Both statements I and II are true Both statements I and II are falseQUESTION 5 The term "polymorphism" means: A method can have multiple return types. A class can have multiple names. The exact method that is called is determined by the object's type, not the variable's type. The exact method that is called is determined by the variable's type, not the object's type.Please answer the following questions in your definition: 3. How can we access the class members?
