What else can I help you with?
Can a parent class access the functions of child class?
no, Parent class can not access the members of child class ,but child class can access members of parent class
Is it true that a derived class inherits all the members of its base class?
False. A derived class inherits the public and protected members of its base class. Private members of the base class cannot be inherited.
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.
What do you mean by protected derivation of a sub class from base class?
When you derive a class (the sub-class) from a base class using protected access, all public members of the base class become protected members of the derived class, while protected members of the base class will remain protected. Private members are never inherited so they remain private to the base class. By contrast, if you use public inheritance, the public members of the base class remain public to the derived class, while protected members of the base class remain protected in the derived class. If you use private inheritance, both the public and protected members of the base class become private to the derived class. Note that accessibility cannot be increased, only reduced or left the same. That is, a protected member of a base class cannot be inherited as a public member of a derived class -- it can only be declared private or remain protected. Note also that accessibility is viewed from outside of the derived class. That is, all members of a base class other than the private members are inherited by the derived class and are therefore fully accessible to the derived class. But from outside of the derived class, all base class accessibility is determined by the access specified by the type of inheritance.
How you declare class scoped variables and member functions?
To scope class members to the class (rather than to instances of the class), declare them as static members of the class. Static members are accessible even when no instances of the class exist. As such, static member functions do not have access to a 'this' pointer, unlike ordinary (nonstatic) member functions.
Can a parent class access the functions of child class?
no, Parent class can not access the members of child class ,but child class can access members of parent class
Is it true that a derived class inherits all the members of its base class?
False. A derived class inherits the public and protected members of its base class. Private members of the base class cannot be inherited.
Who was the last horse to win the tripple crown?

What is public private protected variable function?
The public, protected and private keywords only apply to object oriented programming languages. They are used to determine the accessibility of specific class members and their bases. Private members are only accessible to the class and to friends of the class. Protected members are the same as private but are also accessible to derivatives of the class. Public members are accessible to all code. When applied to base classes, the public, protected and private keywords can be used to either maintain or reduce the accessibility of the base class members (but never to increase their accessibility). When declared public, the accessibility of the base class members remains as defined by the base class. When declared protected, the public members become protected members. And when declared private, all members of the base class become private members. As well as defining the overall accessibility of the base class members, the accessibility of individual base class members can also be specified.
Are sharks and rays examples of what kind of fishes members of the class Chondrichthyes?
They are members of cartilaginous class of fish.
What Sharks and rays are examples of what kind of fishes members of the class Chondrichthyes?
They are members of cartilaginous class of fish.
When was Affirmed Handicap created?
Affirmed Handicap was created in 1979.
Are the methods or members of static class static?
A static class may or may not have static members. Adding the static keyword to the class definition won't change this. Note that an inner class which is not static may not contain static members (unless those members are also declared final).
What is static class?
A static class is a class where all the members are declared static.
