How can I access protected class members?
The protected members are inherited by the child classes and can access them as its own members. But we can’t access these members using the reference of the parent class. We can access protected members only by using child class reference.
Can protected members be accessed by member functions?
Protected members that are also declared as static are accessible to any friend or member function of a derived class. Protected members that are not declared as static are accessible to friends and member functions in a derived class only through a pointer to, reference to, or object of the derived class.
How do you inherit protected members in C++?
Protected Inheritance − When deriving from a protected base class, public and protected members of the base class become protected members of the derived class. Private Inheritance − When deriving from a private base class, public and protected members of the base class become private members of the derived class.
How do you access protected methods outside a class?
The protected access modifier is accessible within the package. However, it can also accessible outside the package but through inheritance only. We can’t assign protected to outer class and interface. If you make any constructor protected, you cannot create the instance of that class from outside the package.
How do I access protected variables?
Protected Access Modifier – Protected Variables, methods, and constructors, which are declared protected in a superclass can be accessed only by the subclasses in other package or any class within the package of the protected members’ class. The protected access modifier cannot be applied to class and interfaces.
How can a protected member be accessed Mcq?
How can a protected modifier be accessed? Explanation: The protected access modifier is accessible within package and outside the package but only through inheritance. The protected access modifier can be used with data member, method and constructor. It cannot be applied in the class.
Can protected members be accessed by objects in C++?
A class in C++ has public, private and protected sections which contain the corresponding class members. Protected members in a class are similar to private members as they cannot be accessed from outside the class. But they can be accessed by derived classes or child classes while private members cannot.
Can subclass access private members?
A subclass does not inherit the private members of its parent class. However, if the superclass has public or protected methods for accessing its private fields, these can also be used by the subclass. A nested class has access to all the private members of its enclosing class—both fields and methods.
Who can access class member with private modifier?
The private modifier specifies that the member can only be accessed in its own class. The protected modifier specifies that the member can only be accessed within its own package (as with package-private) and, in addition, by a subclass of its class in another package.
