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.
Which C plus plus keyword allows a function outside of a class to access private class members?
The keyword is friend. The external function must be declared a friend of the class (from within the class itself) in order to become a member of the class and thus gain access to the private (and protected) members of the class.
What is meant by private access in c plus plus?
It isn't. Private is the default access for class members. For struct members, the default access is public. Aside from default access, a class and a struct serve the same purpose; to define a class. As such, the following class definitions are equivalent: class X { int a; }; struct Y { private: int b; }; Typically, we use a struct to define simple data types with trivial construction and use class for more complex data types, often to encapsulate an invariant or to acquire a resource, hiding the implementation details from consumers using private access.

Different access specifies in C plus plus?
Public members and methods of a class are universally accessible. Protected members and methods of a class are accessible to methods of instances of that class and its derived classes. Private members and methods of a class are accessible only to methods of instances of that class.Class A has three members: public_member, protected_member, and private_member, which have access corresponding to their names. Class A has access to all three. Class B, derived from class A, has access to public_member and protected_member, but not private_member. Unrelated class C has access only to public_member.
Is there a file concept in c plus plus?
