Week 7

Question 1

is a way of writing code where we group related data and actions together into objects.

Answer 1

OOP (Object-Oriented Programming)

Question 2

are the things you think about first in designing a program and they are also the units of code that are eventually derived from the process.

Answer 2

Objects

Question 3

is an instance of a class. It represents a real-world entity with attributes (data members) and behaviors (member functions).

Answer 3

Objects

Question 4

It is created from a class.

Answer 4

Objects

Question 5

is an object-oriented programming language.

Answer 5

C++

Question 6

are basically variables and functions that belongs to the class.

Answer 6

Attributes and Methods

Question 7

These are often referred to as “class members”.

Answer 7

Attributes and Methods

Question 8

Only the specification for the object is defined; no memory or storage is allocated. To use the data and access functions defined in the class, you need to create objects.

Answer 8

Attributes and Methods

Question 9

is a user-defined data type that we can use in our program, and it works as an object constructor, or a “blueprint” for creating objects.

Answer 9

class

Question 10

is a user-defined data type, which holds its own data members and member functions, which can be accessed and used by creating an instance of that class. A C++ class is like a blueprint for an object.

Answer 10

Class

Question 11

When it is defined, only the specification for the object is defined; no memory or storage is allocated. To use the data and access functions defined in the class, you need to create objects.

Answer 11

Class

Question 12

Information an object has (e.g., a car’s color or speed).

Answer 12

Data (Attributes)

Question 13

Actions an object can do (e.g., a car can start or stop). This makes programs organized, reusable, and easier to manage because everything related is kept together.

Answer 13

Behavior (Methods)

Question 14

are the data variables and member functions are the functions used to manipulate these variables together, these data members and member functions define the properties and behaviour of the objects in a Class.

Answer 14

Data Members

Question 15

is a special method that is automatically called when an object of a class is created.

Answer 15

Constructor

Question 16

is also a special member function like a constructor. -_________ destroys the class object created by constructors.

Answer 16

Destructor

Question 17

is the last function that is going to be called before an object is destroyed. It is used to free resources like memory, close files, or clean up when an object is no longer needed.

Answer 17

Destructor

Question 18

Functions are defined directly inside the class.

Answer 18

Inside Class

Question 19

Treated as inline by default, improving performance for small functions.

Answer 19

Inside Class

Question 20

Good for small, simple functions.

Answer 20

Inside Class

Question 21

Functions are declared inside the class but defined outside** using ::.

Answer 21

Outside Class

Question 22

Keeps the class clean and organized, especially for large functions.

Answer 22

Outside Class

Question 23

Preferred for complex or long functions.

Answer 23

Outside Class

Question 24

The public keyword is an ________

Answer 24

Access Specifiers

Question 25

Define how the members (attributes and methods) of a class can be accessed. In the example above, the members are public - which means that they can be accessed and modified from outside the code.

Answer 25

Access Specifiers

Question 26

members are accessible from outside the class

Answer 26

public

Question 27

members cannot be accessed (or viewed) from outside the class

Answer 27

private

Question 28

members cannot be accessed from outside the class, however, they can be accessed in inherited classes

Answer 28

protected

Question 29

are declared inside a class and are used to store values in an object. Each object has its own copy of instance variables that are not shared between other objects.

Answer 29

Instance Variable

Question 30

It can be declared in a class or a function. When declared in class, it is shared between all the objects of that class.

Answer 30

Static Variable

Question 31

We can access a ________ by class name using the scope resolution operator or by the object of the class using a dot (.) operator.

Answer 31

Static Variable

Question 32

Each object does not have a separate copy of ________ so it can't be initialized using a constructor. They are initialized outside the class using the class name and scope resolution operator.

Answer 32

Static Variable

Question 33

are used to store or process data stored in instance variables and are used only by the object of the class

Answer 33

Instance Methods

Question 34

When a function is declared in a class, it is called ______

Answer 34

Method

Question 35

Are defined inside a class using the keyword static.

Answer 35

Static Methods

Question 36

These methods are bound to the class and not to the object, which means that these methods can be called using the class name, and calling the methods using the object name is not necessary. However, the object of the class can also access the static methods using the object name.

Answer 36

Static Methods
