Answer Posted / mms zubeir
As I answered one of the questions here, the abstraction is
nothing but declaration of a concept in software terms
which does not exist in real-world.
For example, mango, drumstick, brinjal, potato are all
vegetables. But "Vegetable" is just a concept and it has no
real-world existance.
To represent these kind of concept in software terms, we
need abstration.
On the other hand, the mango, brinjal, ... are all have
concrete implementations since they have certain properties
and can do some operations on them in the real world.
I couldn't get the third question "abstraction for stack",
but I try to answer with what I understood.
Normally, stack's operations include push, pop, top, size,
empty e.t.c. If we define an interface with these, it ll be
an abstraction for stack. Let me know if it doesn't answer
your question.
