Which base class member functions are not inherited by a derived class?
Derived classes only inherit the protected and public members of their base classes. Private member functions cannot be inherited by a derived 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.
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.
What are Public and Private inheritance in c plus plus?
Public, protected and private inheritance determine how the public and protected base class members are inherited by the derived class. Private members are never inherited and are therefore unaffected by the type of inheritance (they remain private to the base class). The following table summarises how inheritance affects accessibility of base class members with respect to the derived class: public inheritanceprotected inheritanceprivate inheritancepublic member of base classpublic member of derived classprotected member of derived classprivate member of derived classprotected member of base classprotected member of derived classprotected member of derived classprivate member of derived classprivate member of base classprivate member of base classprivate member of base classprivate member of base class Note that accessibility to individual public and protected base class members can be overridden within the derived class, regardless of the type of inheritance specified.
What specifies private access modifier and private base class?
A private variable is something that is not visible outside the class. A private class is one that cannot be inherited
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 is the difference between the direct and indirect base class?
Direct base classes are those that are specified in a derived class' inheritance declaration. Indirect base classes are those that are inherited via the direct base classes. class A{}; class B : public A{}; class C : public B{}; With respect to C, B is direct while A is indirect. With respect to B, A is direct.
What are the things not inherited from parent class in Java?
Private members are not inherited from the parent class.
What is an inheritance.Explain different types of inheritance?
In Computer Programming, inheritance essentially refers to the re-use of code. For example, in C++, a base class will contain functions and members which can be attributed to other classed. This base class can then be inherited by another class, assuming all of the base class functions and member, but also keeping its own.
What is multilevel inheritance in C plus plus?
Multi-level inheritance involves at least 3 classes, a, b and c, such that a is derived from b, and b is derived from c. c is therefore the least-derived base class, b is an intermediate base class and a is the most-derived class.
Does Every class has a toString method and an equals method inherited from the Object class?
Yes - in Java, every class has this method, which is inherited from the Object class. Often, the inherited method does nothing particularly useful, but you can override it with your own implementation.
Any class may be inherited by another class in the same package?
false sealed classes cannot be inherited
