INTERVIEW QUESTIONS C++ INHERITANCE IN C++ DETAILS

Question: What does inheritance means in C++? What are the different forms of inheritance? Give an example for each.

Answer: when a class is derived from another predifined class,then the process of deriving is known as inheritance. different forms of inheritance are single inheritance ,multiple,multilevel, and hierarchical.

Inheritance is the mechanism of class by which we can inherit properties of base class to derived class.The different forms of inheritance are as follows<br>1)Single<br>2)Multiple<br>3)Multilevel<br>4)Multipath<br>5)Hybrid<br>6)Hierarchal Source: CoolInterview.com

Inheritance is a process to create derived class from executing class.Executing class is called base class.In other ways say the derived class aquires some properties of base class.<br>simple example given below<br>claa abc<br>{<br>protected:<br>int x;<br>int y;<br>};<br>class def:abc<br>{<br>private:<br>int z;<br>public:<br>void display()<br>{<br>x=10;<br>y=20;<br>z=x+y;<br>cout<<z<<"<br>";<br>}<br>};<br>void main()<br>{<br>class def o;<br>o.display();<br>getch();<br>} Source: CoolInterview.com

INHERITANCE:Inheritance is the process by which objects of one class acquire the properties of objects of another class & the mechanism of deriving a new class from old class is called inheritance<br>EXAMPLE:<br>polymorphism<br>several types of inheritance:<br>single inheritance:A derived class with one base class is called single inheritance<br>EXAMPLE:<br> A<br> |<br> B<br>multi level inheritance:The mechanism of deriving a class from another 'derived class' is known as multi level inheritance<br>EXAMPLE:<br> A<br> |<br> B<br> |<br> C <br>multiple inheritance:One with several base classes is called multiple inheritance<br>EXAMPLE: <br>A B<br> C <br>hybrid inheritance:One base class deriving more than derived classes is called hybrid inheritance<br>EXAMPLE:<br> A<br>B C<br> D<br>hierarchical inheritance:One class may be inherited more than one base class is called hierarchical inheritance<br>EXAMPLE:<br> A<br>B C D Source: CoolInterview.com

Inheritance is one of the feature of C++.It means inheriting new form from existing one. Here existing class is called base class and new class is derived class. Derived class contain few features of base classes. Types are multiple, multilevel,single,hybrid inheritance. If a is base class and b is derived from a then it is single inheritance. If v and c are derived and d i derived from b as well as c then it is hybrid. if b is taken from a c from b then it is multilevel. If b c r derived from a then it is multiple.

Inheritance is a situation in which a class derived a set of attributes and related behavior from a parent class. Source: CoolInterview.com

Inheritance is the process in which objects of one class acquires the property of another class. <br><br>There are 5 types of inheritance:<br>1)single inheritance.<br>2)multiple inheritance.<br>3)multi-level inheritance.<br>4)hybrid inheritance.<br>5)hierarchical inheritance.

Inheritance is a process by which objects of one class acquire the properties of objects of another class.It supports HIERARCHICAL classification as well as it provides RE USABILITY. This means that we can add additional features to an existing class without modifying it.<br><br>In C++ terminology a class that inherited is refer to as a base class. The class that does inheriting is called a derived class. Further a derived class can use as a base class to another class.<br><br>Inheritance is what that separates abstract data type (ADT) progarming from OO programing. Source: CoolInterview.com

inheritance means the process of accessing the property of one class through objects to another class.it is one of the important concept of oops..any language which support inheritance +data bynding is known as object oriented programming language.there are 5 types of inheritance.<br>1.single inheritance<br>2.multiple inheritance<br>3.multilevel inheritance<br>4. hierarchical<br>5.hybrid<br> Source: CoolInterview.com

Modern object oriented language that supports the features such as <br>Hiding<br>Inheritance<br>Polyphormism<br>Virtual functions<br>Inheritance is one of the most important key concept in c++.The mechanism of deriving a new class from an old one is called inheritance or derivation.

Inheritance is one of the feature of C++.It means inheriting new form from existing one. Here existing class is called base class and new class is derived class.inheritance is a process in which the function of the object of derived class can access the funcnality of the function of the object of another class . which is knewn as base class.there are following form of inheritance-<br>1.single inheritance<br>2.multiple inheritance<br>3.multilevel inheritance<br>4. hierarchical<br>5.hybrid<br><br><br> Source: CoolInterview.com
