Lesson 4: Differences between procedural and object-oriented language

Question 1

can you name 3 languages used in procedural programming ?

Answer 1

Fortran, ALGOL, COBOL, BASIC, Pascal and C

Question 2

what does IDE stand for ?

Answer 2

integrated development environments

Question 3

PP: In procedural programming, program is divided into small parts called ……. ?

Answer 3

functions.

Question 4

OOP: In object-oriented programming, program is divided into small parts called …… ?

Answer 4

objects.

Question 5

PP: Procedural programming follows a ……

Answer 5

top down approach.

Question 6

OOP: Object oriented programming follows …..

Answer 6

bottom up approach.

Question 7

PP: TRUE OR FALSE: Adding new data and functions is easy ?

Answer 7

FALSE (Not easy)

Question 8

What is procedural programming?

Answer 8

A programming approach where a program is broken into step-by-step procedures or functions.

Question 9

What does “top-down approach” mean?

Answer 9

Starting with the whole problem and breaking it down into smaller procedures.

Question 10

What is a procedure (or function)?

Answer 10

A set of instructions that performs a specific task in a program.

Question 11

Can procedures call other procedures?

Answer 11

yes, procedures can call other procedures during program execution.

Question 12

Why are programs broken into smaller procedures?

Answer 12

To make the program easier to understand, manage, and debug.

Question 13

What tool do programmers use to write and manage procedural code?

Answer 13

An Integrated Development Environment (IDE).

Question 14

What does each procedure mainly contain?

Answer 14

A series of computational steps or instructions.

Question 15

What is object-oriented programming (OOP)?

Answer 15

A programming approach that uses classes and objects to build reusable code.

Question 16

What does “bottom-up approach” mean in OOP?

Answer 16

Starting with small classes and building the full program from them.

Question 17

What is a class?

Answer 17

A blueprint that defines attributes and methods for objects.

Question 18

What is an object?

Answer 18

A specific instance of a class with actual values for its attributes.

Question 19

What is the difference between a class and an object?

Answer 19

A class is a blueprint; an object is a real example made from that blueprint.

Question 20

What are attributes?

Answer 20

Variables that describe an object, such as colour or wheels.

Question 21

What are methods?

Answer 21

Functions inside a class that perform actions for objects of that class.

Question 22

Why doesn’t changing one object affect others?

Answer 22

Because each object has its own values separate from the class and other objects.

Question 23

Give two examples of object-oriented programming languages.

Answer 23

Python and Java

Question 24

COM: How is a program divided?

Answer 24

Procedural: into functions

OOP: into objects

Question 25

What approach does each use?

Answer 25

Procedural: top-down OOP: bottom-up

Question 25

Which is easier to extend?

Answer 25

Procedural: harder to add data/functions OOP: easier to add data/functions

Question 26

How is data protected?

Answer 26

Procedural: little or no data hiding OOP: data hiding improves security

Question 27

What is the main focus?

Answer 27

Procedural: functions OOP: data and objects

Question 28

Which models real life better?

Answer 28

Procedural: less realistic OOP: based on real-world objects

Question 29

Give language examples.

Answer 29

Procedural: C, Fortran, Pascal, BASIC OOP: C++, Java, Python, C#
