Intro to OOP

Question 1

First OOP Language, introduced
object-oriented programming concepts
such as object, class,
etc.

Answer 1

SIMULA (Simulation Language)
Creators: Ole-Johann Dahl and Kristen Nygaard
Fathers of Object Technology

Question 2

led a team that developed
Smalltalk at Xerox PARC
- inspired by Simula,
- Coined the term “Object
Oriented Programming”

Answer 2

Alan Kay

Question 3

implemented “C with Classes” aka C++ - Became the most widely used OOP language

Answer 3

Bjarne Stroustrup

Question 4

developed Java (former name is Oak)
- Simplified C++

Answer 4

James Gosling

Question 5

4 Approaches to Software Development

Answer 5

Top-Down Programming
Bottom-Up Programming
Modular Programming
Structured Programming

Question 6

the programmer decides what major actions the program
must take

rather than worry about the details of how it is done, the
programmer defines a function that will handle that
later

Answer 6

Top-Down Programming

Question 7

starts by defining a simple function that might be useful in
solving a more complex problem

Answer 7

Bottom-Up Programming

Question 8

4 Main Python Coding Styles

Answer 8

Imperative
Functional
Object-oriented
Procedural

Question 9

Like math: treats everything like a math equation
Make use of higher-order functions for data manipulation

Answer 9

Functional Style

Question 10

focus is on how a program operates. Changes the state information as needed in order to achieve a goal

Answer 10

Imperative Style

Question 11

What Coding style does this code snippet exemplify:

sum = 0
for x in my_list:
sum += x
print(sum)

Answer 11

Imperative Style

Question 12

coding is all about increasing an application’s ability to reuse code and make it easier to understand

Answer 12

Object-Oriented Programming

Question 13

What Coding style does this code snippet exemplify:

class ChangeList(object):
def __init__(self, any_list):
self.any_list = any_list
def do_add(self):
self.sum = sum(self.any_list)
create_sum = ChangeList(my_list)
create_sum.do_add()
print(create_sum.sum)

Answer 13

Object Oriented Programming

Question 14

The __________________ relies on procedure calls to create modularized code. This approach simplifies your application code by breaking it into small pieces that a developer can view easily.

Answer 14

Procedural Style

Prioritizes functions as well as sequence
of actions to be done

Answer 17

POP

Prioritizes data

Answer 18

OOP

Question 19

Top-down Approach

Answer 19

POP

Question 20

POP vs OOP

Bottom Up Approach

Answer 20

OOP

Question 21

POP vs OOP

No access modifiers

Answer 21

POP

Question 22

POP vs OOP

Has access modifiers (ie. public, private, protected, default)

Answer 22

OOP

Question 23

POP vs OOP

Data can move freely
from function to
function in the system

Answer 23

POP

Question 24

POP vs OOP

Objects can move and communicate
with each other through member
functions

Answer 24

OOP

Question 25

POP vs OOP To add new data and function is not so easy

Answer 25

POP

Question 26

POP vs OOP Can easily add new data and function

Answer 26

OOP

Question 27

POP vs OOP Most function uses Global data for sharing that can be accessed freely from function to function in the system

Answer 27

POP

Question 28

POP vs OOP Data can not move easily from function to function,it can be kept public or private so we can control the access of data

Answer 28

OOP

Question 29

POP vs OOP does not have any proper way for hiding data so it is less secure

Answer 29

POP

Question 30

POP vs OOP provides Data Hiding so provides more security

Answer 30

OOP

Question 31

POP vs OOP Overloading is not possible

Answer 31

POP

Question 32

POP vs OOP Overloading is possible in the form of Function Overloading and Operator Overloading

Answer 32

OOP

Question 33

is a paradigm that uses classes and objects to create models based on the real-world environment.

Answer 33

Object-Oriented Programming (OOP)

Question 34

Defines attributes (or properties) and behavior and dictates the concept

Answer 34

Classes

Question 35

Instances of Classes

Answer 35

Objects

Question 36

A way for the programming language to represent real-world objects as software objects

Answer 36

Classes

Question 37

is when we forget about details of how something works and just concentrate on using it. Devil is in the details :>

Answer 37

Abstraction

Question 38

Data hiding. A Class can have properties that cannot be accessed directly

Answer 38

Encapsulation

Question 39

employs the use of Parent and Child classes (Super and Subclasses)

Answer 39

Inheritance

Question 40

Use of a class exactly like its parent so there’s no confusion with mixing types. But each child class keeps its own methods as they are.

Answer 40

Polymorphism

Question 41

Focuses on the essentials and ignores the irrelevant

Answer 41

Abstraction

Question 42

Denotes the essential characteristics of an object that distinguish it from all other kinds of objects providing well-defined boundaries, relative to the perspective of the viewer

Answer 42

Abstraction
