Object-oriented Programming Language Features

Question 1

What is Object oriented programming?

Answer 1

In object oriented programming we combine a group of related variables and functions into a unit, we call that unit an object. We call the variables (“properties”) and we call the functions as (“methods”)

Question 2

Overloading

Answer 2

Functions overloading creates multiple functions from the same name with different parameters.

Question 3

Polymorphism

Answer 3

Polymorphism (having many forms)

Means that code, operates or objects can behave in some situations differently by functions overloading

Question 4

Inheritance

Answer 4

Inheritance is big part of object-oriented programming,allowing a new class inherited from an existing class instead of writting completely new data members and member functions. The existing class is called the base class, and the new class is a derived class.

Question 5

Data hiding

Answer 5

Encapsulation is the container that can hide data inside an object, allowing the programmer to focus on a higher level of coding, called abstraction, using methods to manipulate data rather than needing to code these actions

Question 6

Encapsulation

Answer 6

Encapsulation binds data and functions that manipulate the data together, keeping both safe from outside interference and misuse. Data encapsulation leads to the concept of data hiding

Question 7

Re-usability

Answer 7

The techniques detailed on this page all help to make code and objects very
 re-usable usable. A base class defines the core of the derived objects removing the need to code and recode their methods and properties.
