There are only two types of inheritance to begin with: single inheritance and multiple inheritance. Since they are mutually exclusive there is no such thing as hybrid inheritance.

In Java what is hybrid inheritance?

Java does not support the ability for one class to extend more than one other class. However, Java does allow for one class to implement any number of interfaces.Let us consider the below example for hybrid inheritance.public class A extends C implements D, E {}Here A extends C which is direct single inheritance, By implementing D & E we are trying to achieve multiple inheritance to the limit that Java allows us. And if C in turn has extended some other class then we have multi level inheritance as well.This can be termed as Hybrid inheritance. The presence of more than one form of inheritance.


Why is cyclic inheritance not in any programming language?

Cyclic inheritance is physically impossible. A base class cannot inherit from one of its own derivatives any more than you could inherit some generic trait from one of your own descendants. Inheritance is strictly a one-way street.


Type of inheritance?

There are 2 Types of genetic Inheritance. 1. Polygenic inheritance, also known as quantitative or multi-factorial inheritance refers to inheritance of a phenotypic characteristic (trait) that is attributable to two or more genes and their interaction with the environment. Polygenic traits do not follow patterns of Mendelian inheritance (qualitative traits). Instead, their phenotypes typically vary along a continuous gradient depicted by a bell curve. Eye color and skin color are both polygenetic traits. 2. Monogenic inheritance is controlled by a single gene, as opposed to multigenic.


Drawbacks of multiple inheritance in c plus plus?

There are no drawbacks to multiple inheritance if multiple inheritance is precisely what is required to achieve your goal. If there are any drawbacks then it is only because of poor design, not multiple inheritance itself. For instance, when designing classes to simulate vehicles, an amphibious vehicle would inherit the properties of both an off-road vehicle and a marine vehicle, therefore multiple inheritance would be an appropriate usage.


C plus plus programming language program for hybrid inheritance?

There's no such thing as hybrid inheritance in C++. Hybrid inheritance implies two or more different types of inheritance but there are really only two types of inheritance in C++ and they are mutually exclusive: single inheritance and multiple inheritance. A class that inherits directly from one class uses single inheritance. A class that inherits directly from two or more classes uses multiple inheritance. The only way to combine these two inheritance patterns is through multi-level inheritance, where a class inherits directly from one or more derived classes. However, whenever we create a derivative, we're only concerned with the base class or classes we are directly inheriting from. The fact they may or may not be derivatives themselves is largely irrelevant from the viewpoint of the derivative. Indeed, the only time we really need to consider one of the lower bases classes is when we need to explicitly invoke a virtual function of that particular class, as opposed to implicitly invoking the most-derived override of that function as we normally would. However, this is really no different to a derived class override invoking its direct base class method. Virtual base classes are also thought of as being a type of hybrid inheritance, however virtual base classes merely determine which class is responsible for the construction of those classes. Normally, a derived class is responsible for the construction of all its direct base classes, which must be constructed before the derived class can begin construction. In turn, those base classes are responsible for the construction for their own base classes. In this way, derived classes are automatically constructed from the ground up, base classes before derived classes, in the order declared by the derived class. For example, consider the following hierarchy: struct X {}; struct Y : X {}; struct Z : Y {}; Z inherits from Y so in order for a Z to exist we must first construct a Y. By the same token, Y inherits from X so in order for a Y to exist we must first construct an X. Thus when we initiate construction of a Z, that initiates construction of a Y which initiates construction of an X. Now consider a virtual base class: struct X {}; struct Y : virtual X {}; struct Z : Y {}; The construction sequence is exactly the same as before (X before Y before Z), the only difference is that when we now instantiate a Z, as the most-derived class in the hierarchy it becomes responsible for the construction of the virtual X. Z is also (still) responsible for the construction of a Y, but Y no longer needs to construct an X because a (virtual) X already exists. Virtual base classes become more relevant in multiple inheritance, where two or more base classes share a common base class: struct W {}; struct X : virtual W {}; struct Y : virtual W {}; struct Z : X, Y {}; Here, Z uses multiple inheritance from X and Y. Both X and Y use single inheritance from W. Without virtual inheritance, Z would inherit two separate instances of W, specifically X::W and Y::W. But by declaring W as a virtual base of X and Y, the most-derived class, Z, becomes responsible for the construction of W, as well as its direct base classes, X and Y. Neither X nor Y need to construct a W because a W will already exist. Thus X::W and Y::W now refer to the same instance of W. Note that we do not need to write any additional code for this mechanism to work. The virtual keyword alone is all we need. Even if X or Y provided explicit initialisation of W, those initialisers would be ignored by the compiler since initialisation of W is automatically the responsibility of the most-derived class. The only time those explicit initialisers would be invoked is if we explicitly instantiate an instance of X or Y, because then X or Y become the most-derived class.

Are hybrid cars more fuel efficient?

It depends on the type of Hybrid. A Hybrid HUMVEE for example still gets poor gas milage compared to a regular non-hybrid Honda Civic. However, a hybrid version of ANY car will be more fuel efficient than their non-hybrid types. It just depends on each individual car's ability.

Getting the Right Hybrid Fuel?

Hybrid cars run off of the same types of fuel that any other car runs on. The only thing that you really need to take into account when you're buying a hybrid is fuel octane. That is, hybrid cars generally need a higher octane fuel than other cars do. If you don't get the right hybrid car fuel, you can end up causing a whole lot of problems in your engine.

Do you tithe an inheritance?

Only if you feel like it.Additional Info:According to the Bible only ancient Israel was required to pay tithes, and the tithes did not consist of money.The Bible never commands Christians to tithe. In fact no Christian (e.g, Apostles) mentioned in the Bible practiced tithing in any form.The New Testament encourages voluntary, Spirit-led giving. With that said, you can give from an inheritance. You can give any amount to anyone you want.

My husband received an inheritance we live in Virginia if we divorce am I entittled to any of it?

It depends on the wording of the inheritance. If you are already divorced, no, you are not entitled to any of it. If you are in the process, it is an asset that will be divided.
