What are the characteristic of Object Oriented programming?

Answer 1

the features of oop are:

1. Emphasis is on data rather than procedure.
2. Programs are divided into what are known as objects.
3. Data structures are designed such that they characterize the objects.

4. Functions that operate on the data of an object are tied together in the data structure.

5. Data is Hidden and cannot be accessed by external functions.

6. Objects may communicate with each other through functions.
7. New data and functions can be easily added whenever necessary.
8. Follows bottom-up approach in program design.

others are :

· Robust

· Multi threaded

· Architecture Neutral

· High Performance

· Distributed

· Dynamic

Answer 2

The key feature is abstraction: you concentrate in identifying the 'objects' that act in your business model, and the relations among objects.

Each object maintains its internal state exposing the 'methods' (actions) that you can call to change the state of the object.

The object itself can relate to other objects just calling the methods the provide the actions needed.

So you can implement a 'car' without the need to understand its internals: you can just 'ask' the car to start (e.g. car->start ()).

Another key feature is inheritance: you can abstract common features and behaviours into more generic objects, from which more detailed objects derive their characteristics.

For example, you can define the concept of 'vehicle' with some common methods (start, stop, ...), and derive from it the car, the bike, the truck, etc.

There is more to say, but this is a top level view of the approach to OO programming.

Answer 3

One of the reasons to write your code in object oriented format is that you can re-use the code you have written in your other programs. Another reason to do this is you can easily read the code you have written and keep it organized.

Answer 4

An object oriented programming language is, well, any programming language that has objects. For example, in Python, an example of an OOPL:

>>> import re

>>> match = re.search('a', 'abc')

>>> match

<_sre.SRE_Match object at 0x1004c3100>

An object is essentially an imaginary "container" of data, and points to the location of your data in memory.

Answer 5

Some of the major features of object oriented programming are:

• Inheritance
• Polymorphism
• Encapsulation
• Data hiding
• Abstraction
• etc.

Answer 6

I personally o not think object oriented programming has any advantage to structured programming. That is not the answer you teacher wants so you must find out what answer your teacher wants to the question.

Answer 7

Object oriented programming contains three characterestics they are

1. Encapsulation

2. Polymorphism

3. Inheritance
