Question

What is different between procedural and object-oriented programming?

Match each of the following OOP concepts with its example/description.

Question 2 options:

12345678 Providing a way for an entity to behave in several ways OR providing multiple entities to be treated in a similar way 12345678 A key way of saving having to retype a lot of code for similar but different objects 12345678 The removal of non-essential information 12345678 Allowing which function to be called by an object to be set at runtime instead of when the program is compiled 12345678 Data and functions together as defined by a blueprint and then instantiated with particular values 12345678 When objects communicate with each other they are doing this 12345678 The concept of putting data and functions together in a single form 12345678 Preventing outside code from accessing data that it shouldn't

1. Class and Object 2. Encapsulation 3. Abstraction 4. Data Hiding 5. Polymorphism 6. Inheritance 7. Dynamic Binding 8. Message Passing

Match each step/characteristic of OOA/OOD/OOP with its description.

Question 3 options:

123 During this step in the process, objects are identified and organized 123 During this process the programmer tries to understand the goals of the application 123 In this step, the program is implemented 123 During this step in the process a plan is devised in how an application's purpose will be met by laying out some of the implementation details 123 During this phase the code is tested

1. Object Oriented Analysis 2. Object Oriented Design 3. Object Oriented Programming

Answer 1

1)

procedural programming is Structure oriented

object-oriented programming is Object oriented

2)

In procedural programming ,entire program is divided into small parts which is based on the functions.

In object-oriented programming the entire program is divided into small parts called objects

3)

In procedural programming no access specifier is observed

In object-oriented programming there are three access specifiers which are called

i) Public,

ii) Private and

iii) Protected

4)

In procedural programming there is no data hiding hence it is less secure

In object-oriented programming there is data hiding hence it is more secure

5)

In procedural programming the approach is top down approach

In object-oriented programming the approach is Bottom-up approach

--------------------------------------------------------------------------------------------------

Providing a way for an entity to behave in several ways OR providing multiple entities to be treated in a similar way

-- Polymorphism

A key way of saving having to retype a lot of code for similar but different objects -- Inheritance

The removal of non-essential information -- abstraction

Allowing which function to be called by an object to be set at runtime instead of when the program is compiled -- Dynamic Binding

Data and functions together as defined by a blueprint and then instantiated with particular values -- Class and Object

When objects communicate with each other they are doing this -- Message Passing

The concept of putting data and functions together in a single form -- Encapsulation

Preventing outside code from accessing data that it shouldn't -- Data Hiding

------------------------------------------------------------------------------------------------------------------------

During this step in the process, objects are identified and organized -- Object Oriented Analysis

In this step, the program is implemented -- Object Oriented Programming

During this step in the process a plan is devised in how an application's purpose will be met by laying out some of the implementation details -- Object Oriented Design
