Answer / santosh kumar
Abstraction is one of the most powerful and vital features provided by object-oriented programming language. Modularity is very important in any programming language, it provides flexibility to users for using the programming language. This aspect is well achieved with high performance by the concept of abstraction. In object-oriented programming language the programmer can abstract both data and code when needed.

Answer / rohit shori
data abstraction
3 types:-
Physical level describes how a record (e.g., customer) is
stored.
Logical level: describes data stored in database, and the
relationships among the data.
type customer = record
name : string; street :
string; city : integer; end;
View level: application programs hide details of data
types. Views can also hide information (e.g., salary) for
security purposes.

Answer / prasenjit chatterjee
Abstraction means that just represents the essential
feature of some thing without including much details.
So the data abstraction means that does't define the
internal structure of the data, but allows difference
operations on it. Such data types are called abstract data
type or (ADT), like stack queues are the example of an
abstract data type

What is an accessor in c++?
write a program that reads in a file and counts the number of lines, words, and characters. Your program should ask the user to input a filename. Open the file and report an error if the file does not exist or cannot be opened for some other reason. Then read in the contents of the file and count the number of lines, words, and characters in the file. Also print additional information about the file, such as the longest and shortest words, and longest and shortest lines. For simplicity, we define a word to be one or more characters ending with white space (a space, tab, carriage return, etc.). Functions for checking the types of characters can be found in the ctype.h header file, so you want to include this header file in your program. For example, the sentence below could be all that is in a file. This sentence IT 104 is taught in C++. has 32 characters, one line, and six words. The shortest line is 32 characters. The longest line is 32 characters. The shortest word is 2 characters. The longest word is 6 characters
