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.
For most classes, data members are declared private, thus fully encapsulating the data.
The main features of OOP are the same regardless of the language. They are: encapsulation; data hiding; inheritance; and polymorphism.
Encapsulation.
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!)
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.
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.

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.
The concepts of OOP in C++ are the same as for OOP in any other programming language: abstraction, encapsulation, inheritance and polymorphism.

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

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.
Use "typedef" : both in C and C++.
