OOPS COncepts Are:
Mainly these are the concepts are very important in oops:
Abstraction
Encapsulation
Inheritance
Polymorphism.
Birds Vs Abstractions
Birds: we invented flight based on the mechanism of Birds.
So flight is derived form the base of birds.
Abstraction: Abstraction is a way to remove the association
of the behavior of an object with the actual details behind
the scenes which implement that object's behavior. This
'abstraction' is usually accomplished through the use of
base classes with virtual functions; each derived function
provides the details that implement the behavior behind that
abstraction.
Pen Vs Encapsulation
Pen: Ink is the important component in pen but it is hiding
by some other material
Encapsulation: is a process of binding or wrapping the data
and the codes that operates on the data into a single
entity. This keeps the data safe from outside interface and
misuse. One way to think about encapsulation is as a
protective wrapper that prevents code and data from being
arbitrarily accessed by other code defined outside the wrapper.
Crocodile Vs Polymorphism
Crocodile: live indifferently on land or in the water. In
water it’s Moment very fast compare to land. An animal lives
in different character in different place.
Polymorphism: a single function or single operator has
different character in different place.
Inheritance Vs Human Relationship
Human Relationship: GrandFather-Father-Son
Inheritance:A derived from existing one to new one is known
as Inheritance.
