Programming Paradigms

Question 1

What are the 6 paradigms

Answer 1

Imperative
Procedural
Object-oriented
Event-driven
Declarative
Functional

Question 2

Define imperative programming

Answer 2

-changes the program state by executing a series of commands
-e.g. using varibales to store and iterations

Question 3

Define procedural programming

Answer 3

-related to imperative programming
-organises code into functions which has a sequemce of instructions
-the program is divided into smaller functions that return values

Question 4

Define object-oriented programming

Answer 4

-subordinate of imperative programming
-creates resuable methods and classes
-code is more maintainable

Question 5

What are the 4 principles of object-oriented programming

Answer 5

Encapsulation - binds data and keeps it protected by making the data private within their methods
Inheritance - allows child classes to take charactersitics from a parent class
Abstraction - hides complexity and only shows relevant info
Polymorphism - the same code structure can be used in different forms

Question 6

Define functional programming

Answer 6

-building software with pure functions
-output is returned based on input given with no reliance outside of the function
-

Question 7

Give an example of functional programming

Answer 7

using the square function as there is always the same output for the same input (always a squared number)

Question 8

Define event driven programming

Answer 8

-programs that respond to events or user interactions
-involves real time response
-start - initialise - wait for event

Question 9

Define declarative programming

Answer 9

-programmer specifies result and program solves how to achieve it
-e.g HTML/CSS
