Why you are mark a class protected for inheritance?
Public, Private and Protected "keywards/ access modifiers" are used similarly as they are with variables. Protected variables, methods or class CAN ONLY be used by an inherited class.
Define protected access modifire in c plus plus?
The access privileges in c++ are 1.public 2.private 3.protected and by default its private
Is the default access specifier same as protected?
A private member of a class can only be accessed by methods of that class. A protected member of a class can only be accessed by methods of that class and by methods of a derived class of that class.
When you implement an interface method it should be declared as public in java?
This is not necessarily true. The only rules for this are that interface methods may not be private. They may be public, protected, or have the default (blank) access modifier.
Why can not define private and protected modifiers for variables in interface?
No. Interface variables are supposed to be public static final. Interfaces, like abstract classes, cannot be instantiated, so all variables in an interface must be static final ones. They are public because usually interfaces are used throughout an application, and this will ensure versatility.

What is public derivation in object-oriented programming?
Public derivation or public inheritance means that all the public members of the base calls are declared public in the derived class while the protected members remain protected. Protected inheritance means all the public members of the base class are declared protected in the derived class, as are the protected members. Private inheritance means all the public and protected members of the base class are declared private in the derived class. Private members of the base class are never inherited and are therefore unaffected by inheritance. Note that regardless of the type of inheritance specified, individual non-private members of the base class can be inherited with public or protected access as required of the derived class. The type of inheritance can be therefore be thought of as being the default inheritance for all base class members which can (optionally) be overridden for specific members where required.

What portions of a super class can be used by subclass?

The fields in a c program are by default private is true or not?
I guess you mean C++, not C.Data fields of a structure/union are public by default,those of a class are private by default.
Encapsulation data we can inherit out side the class?
Yes. If the variables are public yes they can be inherited. If they are private then they cannot be inherited. But to access these private variables you can have accessor methods that are public and can be accessed everywhere.
Is it true default access modifire?
Default access modifier is package. So when you want a method or object variable to be visible within a package, you don't have to insert an access modifier. For public, private or protected, you need to metion them in your java code.
Which is java default access specifier?
There is no such thing as an access specifier in Java. There are access modifiers.The default access modifier if unspecified is to allow access to classes in the current package only, except within an interface where the default is 'public'
What are different access specifiers in c sharp?
