Abstraction is generally defined as 'the process of formulating generalised concepts by extracting common qualities from specific examples
-Blair et al, 1991

Abstraction is not a complement for encapsulation.

Encapsulation is information hiding.

Answer / ekta

data abstraction is act of representing essential features
without including background details or explaintation.
FOR EXAMPLE: SWITCH BOARD.. in this we only know that if we
press any switch any electric appliances start working but
we dont know the inner functionality of switch board like
its wire connection, line connection,and etc....

Answer / ramya

Abstraction is of the process of hiding unwanted details from the user.
For example, your program can make a call to the sort() function without knowing what algorithm the function actually uses to sort the given values.

Answer / sudhachandan banerjee

Data abstraction refers to, providing only essential information to the outside word and hiding their background details ie. to represent the needed information in program without presenting the details.

Data abstraction is a programming (and design) technique that relies on the separation of interface and implementation.

Let's take one real life example of a TV which you can turn on and off, change the channel, adjust the volume, and add external components such as speakers, VCRs, and DVD players BUT you do not know it's internal detail that is, you do not know how it receives signals over the air or through a cable, how it translates them, and finally displays them on the screen.

Thus we can say, a television clearly separates its internal implementation from its external interface and you can play with its interfaces like the power button, channel changer, and volume control without having zero knowledge of its internals.

Answer / ahsaan ansari

In another word say "Data Abstraction Emphasis on What rather than How".

Answer / akshita.s

Abstraction is a OOP`s concept,it hides the implementation
details from the end user.we get loose coupling if there is
good abstraction.

Answer / tariq shadid

this style data representations and their associated primitive operations are
encapsulated in an abstract data type or object. The components of this style are
the objects—or, if you will, instances of the abstract data types. Objects are
examples of a sort of component we call a manager because it is responsible for
preserving the integrity of a resource (here the representation). Objects interact
through function and procedure invocations. Two important aspects of this
style are (a) that an object is responsible for preserving the integrity of its
representation (usually by maintaining some invariant over it), and (b) that
the representation is hidden from other objects.

Answer / kamal lochan jena.

It is process of creating a new data_type using encapsulated
items.
Ex: class Name
{
int age;
char Name[20];
public:
getdata();
putdata();
};

Here the class body contains the encapsuleted data items.

Answer / saranya

Write a program to read the data and evaluate the results of the election. Print all output to the screen. Your output should specify: The total number of votes, the number of valid votes and the number of spoilt votes. The winner(s) of the election. Hint: An appropriate search should be used to determine the winner(s). The votes obtained by each candidate sorted in terms of the number of votes obtained. Hint: An appropriate sort should be used to sort the candidate(s). The Source code should be saved as VotingSystem.
