Switch case statement is used when we have multiple conditions and we need to perform different actions based on the condition.

Below is an example in c++.

#include <iostream>
using namespace std;
int main(){

int firstnumber,secondnumber,result,option;
cout<<"-------Calculation of two number---------\n";
cout<<"Enter First Number: ";
cin>>firstnumber;
cout<<"Enter Second Number: ";
cin>>secondnumber;
cout<<"\nSelect a below option to perform the actions\n";
cout<<"1. Addition\n";
cout<<"2. Subtraction\n";
cout<<"3. Multiply\n";
cout<<"4. Division\n";
cout<<"Enter option: "
cin>>option;

switch(option) {
case 1:
result=firstnumber+secondnumber;
cout<<"Result of Addition is "<<result;
case 2:
result=firstnumber-secondnumber;
cout<<"Result of Subtraction is "<<result;
case 3:
result=firstnumber*secondnumber;
cout<<"Result of Multiply is "<<result;
case 4:
result=firstnumber/secondnumber;
cout<<"Result of Division is "<<result;
default:
cout<<"You have select a wrong option";

For main section <html> tag used.
For head section <head> tag used.
For body section <body> tag used.

4. Html tag come in pairs. means there will be an open tag and closing tag.

2. Review their individual LinkedIn pages (noting any connections you may have in common).

3. Review any information about these individuals on the company’s website.

3. Anticipate Questions You Might Be Asked

It’s important to think early on about the questions you may be asked so that you can prepare an articulate and polished response.

These types of general interview questions are often asked, so please prepare for the below points:

1. Can you tell me about yourself?

2. What do you know about our company?

3. Why are thinking about leaving your current job?

4. What interests you about this job?

6. What do you consider to be your greatest strength?

7. Where do you see yourself in 5 years?

4. Conduct a Mock Interview

Doing a practice interview with friends or family members (especially if they have experience interviewing employees themselves).

The practice will be helpful and give you more confidence. Ask for feedback on your answers, your body language, and your preparedness.

Have the mock interviewer ask both common questions as well as offbeat ones to see how well you can think on your feet.

6. This is very common but you have to review Your Facebook and Other Social Media Postings

The employers often review Facebook and other social media sites to get information and background on prospective employees.

So please make sure to review your online postings and pictures and delete any information that is embarrassing or could cast you in a negative

Make sure to arrive at the interview on time (you don’t want the first impression of you to be of a person who can’t be on time). Download directions in advance. Anticipate traffic delays, and get there early (but don’t show up on the company’s doorsteps more than 5 to 10 minutes early). Make sure to turn off your cell phone so it doesn’t ring or buzz during the interview.

4. Work samples such as writings, design layouts, etc. (but make sure you aren’t providing confidential information of your existing employer)

4. After your interview, you should let your professional references know that the employer might be contacting them.

Give them a heads up on the company and job position.

10. Check Out Glassdoor.com

You should check out Glassdoor for reviews of the company.

There may be reviews from current and past employees, along with information on salary and the types of questions interviewers ask at the company.

These reviews can be helpful for background and to give you a sense of employee issues.

Best of luck for Interview

.Net interview questions for 2 years experience

Hi guys,

As per my own experience, I am also attending the interview questions. I am going to share interview questions for .net having experience of 2 years.

First of all, I have listed out the list of questions, after it i will explain in detail.

1. What's class.

Ans: A class is like a blueprint of a specific object and it defines the kinds of data and the functionality their objects will have. It enables you to create your own custom types by grouping together variables of other types, methods and events. In C#, a class can be defined by using the class keyword.Example: Suppose we are going to write a program to create a calculator for some calculation.We required some variable to store the value.We required some variables to show the value.Now there will be a chances to declare more than one variable and function. And these are all variable and function grouping in one memory called class. The all functionality is for calculating something so we can give a class name Calculator.

2. What's is oops concepts.
Ans: The Oops concept is the root of the c#. The concept is a containing of four feature called
1. Polymorphisms
2. Abstractions
3. Inheritance
4. Encapsulation

These all have a such like feature coating which is make C# stronger.

3. Explain encapsulation with example.
Ans: Encapsulation is a part of the oops concept of the c#. Encapsulation is a way to hide the member of the class from outer side access.

Let's take an example,
In touch screen mobile there is a feature of unlocking the mobile through the fingerprints. Just I have to put the finger on the scanner sensor of the mobile and it get unlock. This means there is some internal feature that gets the data from finger , scan, and checks and gives output you are the owner of this mobile or not. and these internal features not showing the user.

So encapsulation means hiding the important features of a class which is not been needed to be exposed outside of a class and exposing only the necessary things of a class.

4. What is the role of polymorphism?
Ans. Polymorphism is a part of the opps concept of the c#. Polymorphism means many forms.

Let's take an example,
In iPhone mobile, there is a single button at the bottom in the center for working almost all work from those button-like, enter, back, lock, unlock, etc,
So you can under there be a common function name with the different parameters make function to define in the many forms.

5. Where we can use inheritance.
Ans. Inheritance is part of the oops concept of the c#. Inheritance is a way to we can reuse the function of the class.

Let's an example.
Commonly the property of my parents hand over by me, and my property is hand over to my child, this property is hand over to his child, which means there is single property use by many.
