What is protected by The Spine?
If your talking about in The Inheritance Cycle. Then, the urgals villages and the town of Carvahall is protected by The Spine.
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.
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.
Programme to implement single and multilevel inheritance taking employee as sample base class in c plus plus?
struct employee { }; struct supervisor : employee { // single inheritance -- a supervisor inherits all the public and protected properties of an employee. }; struct manager : supervisor { // multilevel inheritance -- a manager inherits all the public and protected properties of a supervisor (and therefore an employee). };
Who did Hera protect on Earth?
Hera protected his inheritance from his parents, as they were very rich and he hoped to receive their fortune when they passed.
Difference bitween various visibility modes used c plus plus?
By visibility I assume you mean member accessibility. C++ uses three levels of accessibility: private, protected and public. Private members are only accessible to the class itself and friends of the class. Protected members are the same as private members except derived classes also have access. Public members are fully accessible. With regards inheritance, base class members with greater access than that specified are reduced to the specified access in the derived class. Thus public inheritance has no effect on base class member access. Protected inheritance reduces public members of the base class to protected members of the derived class. Private inheritance reduces both public and protected members of the base class to private members of the derived class. Private members of the base class are never inherited, thus they always remain private to the base class. Note that access to base class members can never be increased through inheritance, only reduced or kept the same. However, as well as defining an overall inheritance access, you can also specify member-wise inheritance access. Thus you could use public inheritance overall, but specify certain public members of the base class to be protected or private in the derived class and/or certain protected members of the base class to be private members of the derived class.
What is visibility mode what are the different inheritance visibility modes support by c plus plus?
There is no such thing as visibility mode in C++. Visibility is a function of information hiding but that relates to the way in which implementation details can be obfuscated within binary executables and libraries where only the interface need be exposed in a plain-text header file. This has nothing whatsoever to do with object oriented programming since information hiding is also possible in C. You probably meant access specifiers. There are three levels: private, protected and public. Private access limits access to the class and to friends of the class. Protected is the same as private but extends access to derivatives of the class. Public access imposes no limits. In terms of inheritance, the specified access level determines the accessibility of the protected and public members of the base class (private members are never inherited and will always remain private to the base class). in essence, members with access greater than the specified inheritance are reduced to the specified access. Thus if you specify protected inheritance, all public members of the base class become protected members of the derivative, while private inheritance reduces all public and protected members to private access. You may also reduce access to specific base class members simply be redeclaring them with the appropriate access.
How do you protect your inheritance if you file bankrupsy?
Inheritance may be protected during bankruptcy by using exemption laws or setting up a trust. It's important to consult with a bankruptcy attorney to understand the options available in your specific situation. Additionally, being transparent with the court about the inheritance is crucial to ensure compliance with bankruptcy laws.
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 kinds of access can a class member have?
Public, protected and private access members.
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.
How does inheritance promote code reuse?
One of the earliest motivations for using inheritance was the re-use of code which already existed in another class. This practice is usually called implementation inheritance.In most quarters, class inheritance for the sole purpose of code re-use has fallen out of favor.The primary concern is that implementation inheritance does not provide any assurance of polymorphic substitutability-an instance of the re-using class cannot necessarily be substituted for an instance of the inherited class. An alternative technique, delegation, requires more programming effort but avoids the substitutability issue. In C++ private inheritance can be used as form of implementation inheritance without substitutability. Whereas public inheritance represents an "is-a" relationship and delegation represents a "has-a" relationship, private (and protected) inheritance can be thought of as an "is implemented in terms of" relationship.
