15 Advanced OOPS Interview Question with Answers1. What is inheritance?Inheritance is the concept that allows one class to take on the methods and properties of another class. In the example of the car, you probably have a car frame that defines the basic structure for the car. The body of the car would inherit the main frame of the car, because it uses the basic car frame as a model. The same is true for your classes. You build a hierarchy for your classes that inherit each other.2. What is a class constructor?A constructor is used when you instantiate a class. The class constructor must have the same name as the class. You can have several overloaded constructors or a constructor with no parameters. You use constructors to initialize certain properties in your class.3. What are overloaded methods?Overloaded methods are the same method name that just contains a different set of parameters. It means you can have the same name for your methods just differentiated by parameters. For instance, you have a car move method. However, you might want to move the car right and forward or left and forward. You could use the same move method just with different parameters, and these are called overloaded methods.4. What is an abstract class?An abstract class cannot be instantiated, but it can be inherited. This means that your inherited class can use the abstract class methods and properties, but the abstract class cannot be called directly. Abstract classes are good for defining global definitions for your inherited classes, so you only need to define these definitions once.5. What does it mean to override a method?When you inherit a class, you can override the parent class methods. When you override a method, you inherit its function, but the class inheriting the parents class method overrides parameters and functionality, so you can redefine how the method acts.6. What is Polymorphism?Polymorphism is nothing butassigning behavior or value in a subclass to something that was already declared in the main class. Simply, polymorphism takes more than one form.7. What is a virtual function?Virtual function is a member function of class and its functionality can be overridden in its derived class. This function can be implemented by using a keyword called virtual, and it can be given during function declaration.8. What is the use of finalize method?Finalize method helps to perform cleanup operations on the resources which are not currently used. Finalize method is protected , and it is accessible only through this class or by a derived class.9. What is an interface?An interface is a collection of abstract method. If the class implements an inheritance, and then thereby inherits all the abstract methods of an interface.10 .Difference between overloading and overriding?Overloading is static binding whereas Overriding is dynamic binding. Overloading is nothing but the same method with different arguments , and it may or may not return the same value in the same class itself. Overriding is the same method names with same arguments and return types associates with the class and its child class.11. What is an abstraction?Abstraction is a good feature of OOPS , and it shows only the necessary details to the client of an object. Means, it shows only necessary details for an object, not the inner details of an object. Example When you want to switch On television, it not necessary to show all the functions of TV. Whatever is required to switch on TV will be showed by using abstract class.12. What is sealed modifiers?Sealed modifiers are the access modifiers where it cannot be inherited by the methods. Sealed modifiers can also be applied to properties, events and methods. This modifier cannot be applied to static members. ow13. can we call the base method without creating an instance?Yes, it is possible to call the base method without creating an instance. And that method should be, Static method. Doing inheritance from that class.-Use Base Keyword from derived class.14. What are all the operators that cannot be overloaded?Following are the operators that cannot be overloaded -.Scope Resolution (:: )Member Selection (.)Member selection through a pointer to function (.*)15. How many instances can be created for an abstract class?Zero instances will be created for an abstract class.MU (Sikkim Manipal University) Project Report Format for BCA, MCA, BSC IT, MSC IT, MBA IT*************************************************************************Cover Page--Title Of Project--Your Name--Roll NoDeclarationCertificateAcknowledgementProject AbstractTable of ContentsIntroduction of ProjectObjectivesProblem StatementRequirement Analysis--System Requirement Specification--Data Flow Diagram--Flow ChartsAnalysis and Design--UML Diagrams--Class Diagram--Sequence Diagram--Object Diagram--Structure Charts--Data Flows--Grant ChartsCodingInterface DesignTesting ResultsUser ManualFuture ScopeConclusionBibliographyStandard MCA / BCA / BE / BSC IT/ PGDIT Project Report Format for IGNOU, SMU, SCDL, YCMOU===================================================Project TitleAcknowledgementTable of Contents/Index with page numberingIntroduction/ObjectivesAdvantages of Your projectSystem Analysis- Identification of Need- Preliminary Investigation- Feasibility Study- Project Planning- Project Scheduling (PERT Chart and Gantt Chart both)- Software requirement specifications (SRS)- Software Engineering Paradigm applied- Data models (like DFD), Control Flow diagrams, State Diagrams/Sequence diagrams, Entity Relationship Model, Class Diagrams/ Data Dictionary- Diagrams/Use-case Diagrams/Activity Diagrams/ Sequence Diagram/ Other DiagramsSystem Design- Modularisation details- Data integrity and constraints- Database design, Procedural Design/Object Oriented Design- User Interface Design- Test Cases (Unit Test Cases and System Test Cases)Coding- Complete Project Coding- Comments and Description of Coding segments- Standardization of the coding- Code Efficiency- Error handling- Parameters calling/passing- Validation checksTesting- Testing techniques and Testing strategies used- Testing Plan used- Test reports for Unit Test Cases and System Test Cases- Debugging and Code improvementSystem Security- Database/data security- Creation of User profiles and access rightsCost Estimation of the Project along with Cost Estimation ModelFuture scope and further enhancement of the ProjectBibliographyReferencesProject Viva Questions====================1.

Explain how you would be an asset to this organization?1.What is VSS (Visual Source Safe) ?

You can use VSS to secure code access among the developer and make control over the access right, also can check for multiple version of code.

2.Assume you have an array that contains a number of strings (perhaps char * a[100]). Each string is a word from the dictionary. Your task, described in high-level terms, is to devise a way to determine and display all of the anagrams within the array (two words are anagrams if they contain the same characters; for example, tales and slate are anagrams.)

Begin by sorting each element in the array in alphabetical order. So, if one element of your array was slate, it would be rearranged to form aelst (use some mechanism to know that the particular instance of aelst maps to slate). At this point, you slate and tales would be identical: aelst.Next, sort the entire array of these modified dictionary words. Now, all of the anagrams are grouped together. Finally, step through the array and display duplicate terms, mapping the sorted letters (aelst) back to the word (slate or tales).

3.What is the difference between a NULL pointer and a void pointer?

A NULL pointer is a pointer of any type whose value is zero. A void pointer is a pointer to an object of an unknown type, and is guaranteed to have enough bits to hold a pointer to any object. A void pointer is not guaranteed to have enough bits to point to a function (though in general practice it does)

4.What is encapsulation technique?

Hiding data within the class and making it available only through the methods. This technique is used to protect your class against accidental changes to fields, which might leave the class in an inconsistent state.

5.Definition of Object Oriented Programming in single line?

Object oriented programming is a programming paradigm which uses objects and its interactions to design applications and computer programs.

6.What is virtual function?

The virtual keyword means that method, property or function can be overridden

7.Whats a Windows process?

Its an application thats running and had been allocated memory.

8.What is programming?

Computer programming is writing or editing a computer program. A computer program is a set of instructions which determine how the computer will react to input when that program is running.

9.What is a debugger?

debugger is a program in which you run another program that you are trying to debug. Inside a debugger, you can step through your program one line or instruction at a time, set break points and have your program run until it hits one, examine the contents of variables and memory, and such other useful things as that.

10.what is a Programming language?

A programming language is a stylized communication technique intended to be used for controlling the behavior of a machine (often a computer). Like human languages programming languages have syntactic and semantic rules used to define meaning.

11.What's the difference between a programming language, a scripting language?

The main difference between a "programming language" (C, C++ etc.) and a "scripting language" (ASP, JSP, JavaScript, VBScript) is that code written in a programming language needs to be compiled before it is run. Once it is compiled, it can be run any number of times.

Scripting languages, on the other hand, are interpreted at run-time. This means that every time you want to run the program, a separate program needs to read the code, interpret it, and then follow the instructions in the code. Compiled code has already been interpreted into machine language, so it is will typically execute faster because the conversion into machine language has already been done.

12.What is difference between overloading and overriding?

Same methods (Names are same) with different signature (parameters) is called overloading, while having same name and parameter functions in base and drive class called overriding.

13.What are the advantages of OOPS?

Advantages of OOPS are Re-usability, Maintainability, Extensibility, Modifiability, Modularity, Simplicity

14.What are the features of OOPS?

These are the main features of OOPS, a) Abstraction b) Encapsulation c) Inheritance d) Polymorphism

15.What is Class and Object

A Class is blueprint or a template to create an Object. Whereas an Object is a an actual instance of a Class.

16.Explain modeling and its advantages?

Modeling is a proven and well-accepted engineering technique which helps build a model. Model is a simplification of reality; it is a blueprint of the actual system that needs to be built.

17.What are the various types of Software Testing?

There are 7 different types of testing are done for a project, they are a) Unit Testing, b) Integration Testing, c) System Testing, d) Acceptance Testing, e) Alpha and Beta Testing, f) Black Box Testing and g) White Box Testing

18.What is ER Diagram

ER model is a conceptual data model that views the real world as entities and relationships. A basic component of the model is the Entity-Relationship diagram which is used to visually represents data objects.

19.Write a program to add two numbers without using arithmetic operator?

public static void main(String args[]){int a=3,b=5;While(b--)a++;System.out.println("sum is"+a);}

20.Write a program to swap two numbers without using a temporary variable.

public static void main(){int a=4,b=5;a=a+b; //a=9b=a-b; //b=4a=a-b; //a=5System.out.println("After swapping"+a,+b);}

21.Write a program to find largest of 2 numbers without using if-else

void main(){cin>>a>>b;; //let a=3and b=2float c=|(a+b)|/2+|(a-b)|/2; //c=2.5+0.5=3.0cout
