Data encapsulation refers to a means of limiting data access only to those functions that actually require direct access. Object-oriented programming languages such as C++ use access specifiers (public, private and protected) to determine the accessibility (or visibility) of an object's data or, more specifically, its representation.

  • Public member data is accessible to any function (no encapsulation).
  • Private member data is accessible only to the class member functions and to friends of the class (full encapsulation).
  • Protected member data is the same as private member data and is also accessible to implementers of derived classes and to friends of those classes (partial encapsulation).

For most classes, data members are declared private, thus fully encapsulating the data.

What are the main features of OOP in c plus plus?

The main features of OOP are the same regardless of the language. They are: encapsulation; data hiding; inheritance; and polymorphism.


What is the term that describes the hiding of implementation details of objects from each other in a C plus plus class?

Encapsulation.


What is encapsulation in c?

Assume you were asking as in C#, not C. Because C is not an OO language, thus if there is encapsulation, it would be different.The encapsulation in any OO language is to hide the information of data and the implementation detail of a method.For example, you have a bank account as a private data member. Any one can ask you about the Balance of your bank account, e.g. GetDeposits(), an operation that is public. Wait, you now are richer, and you open 2 more bank accounts, the public still has the only accessing method GetDeposits(), to get your total deposits.The encapsulation in this abstraction are:1. The detail, the implementation of GetDeposits(), is not revealed to public.2. The data member, 1 account or 3 accounts, no one got impact, and no one knows. (in fact, no one knows how many bank accounts you have!)


Is it true that wrapping up of data of different types into a single unit is known as encapsulation?

Not quite. Encapsulation means to combine data and the methods that work upon that data into a single unit (an object), such that access to both the data and methods is restricted in a controlled manner. Data-hiding is fundamental to encapsulation.


How does a class in c plus plus enforce data encapsulation?

Data encapsulation is enforced by restricting access to the class members. Access can be specified on a per-member basis, defaulting to private access for a class and public access for a struct. Private members are accessible to class members and to friends of the class. Protected members are the same as private members but are also accessible to derived class members. Public members are fully-accessible. Data members are typically declared private while interfaces are typically declared public or protected.

Why c plus plus is not complete object oriented language?

because c++ supports all the basic concepts of oop :1.objects,2.classes,3.data abstraction and encapsulation,4.inheritance,5.polymorphism,6.dynamic binding,5.message passing.

What is encapsulation and data hiding in dbms?

ODBMS stands for object oriented database management system. Encapsulation in ODBMS can be defined as binding of data together.

Assumptions of 2 phase commit protocol?

to implement real-world entities more and more in computer language and to protect datas we require c++.c++ is basically an object oriented programming language.there are special features which are not present in c such as data encapsulation,data abstraction,polymorphism,inheritance etc.by encapsulation ,we can bind different data types in single unit.by data abstraction ,we can protect our datas.by polymorphism ,we can overload an operator.and by inheritance,we can inherit the properties of the base class.
