Program to reverse a Number C Program

Program to reverse a Number C Program
Please friends to contribute questions of company interviews you attended mail us cinterviews.blogspot.com@gmail.com it will be useful for our job search community.www.cinterviews.com appreciates your contribution

In order to reverse a number you should first input the number and then extract the digits of number one by one. In order to extract digit you can use % operator which results in remainder of division operation. 13%10 is 3. Thus by doing mod 10 you can get rightmost digit of number. After extracting digit you can remove the same from number by storing result of /10 in integer variable. Eg 13/10 is 1.3 but on storing it in integer variable only 1 is stored.

In order to reverse a number using while loop in c language you must run the loop till the number is not 0 that is all the digits haven't been extracted. Assuming that you want reverse of number in variable called y (initial value of y should be zero), you should write y=y*10+extracted digit in while loop.

Consider test input of a=123,y=0

iteration 1
y=0*10+3=3, a=12
iteration 2
y=3*10+2=32, a=1
iteration 3
y=32*10+1=321 a=0

thus we get reverse of number in y.
Below is the code of the Program
 int main()
{
int a;
printf("Enter a number :");
scanf("%d",&a);
int y=0;
while(a)
{
y=y*10+a%10;
a=a/10;
}
printf("\nreverse= %d",y);
getch();
return 0;
}

Business layer Testing
Please friends to contribute questions of company interviews you attended mail us cinterviews.blogspot.com@gmail.com it will be useful for our job search community.www.cinterviews.com appreciates your contribution

This is the type of layer which helps in understanding and determining the errors which are basically associated with the applications of the internet and the business logic of the internet connections. This layer is actually similar to one of the applications which are the stand alone applications. In this application one can employ to the techniques, the white box technique and the black box technique.

In this testing it is also required and important as well that a project manager and all the associated members to the team of the particular project has to plan and schedule and create the procedures for the process to be carried out in a proper manner, so that, it can achieve the desired goals in order to achieve the success of the project and the organization. And in order to achieve this whole target it is very important for the project manager and the associated team members to be to make plans in order to identify the errors and the mistakes which may take place or which are taking place during the entire process.

This helps in not only identifying the errors and mistakes but also the application’s performance requirements,
Data acquisition and transaction processing. Because the project manager Marjory access the program logic he has to employ the white-box approaches for components developed in-house because it proves to be a great help for it.
But still, the primary testing approach for this layer specially is actually the Black Box Testing. It starts by the development of the test drivers to test the units (unit test) the individual component. Then the time for performing the next step comes and it is the system test which has been performed in order to determine that whether all the components work together correctly. If it not so then the corrective actions are taken place as they are very important too in order to achieve the desired tasks and the goals which has been set by the organization.

Explain QTP Testing process?
Please friends to contribute questions of company interviews you attended mail us cinterviews.blogspot.com@gmail.com it will be useful for our job search community.www.cinterviews.com appreciates your contribution

The QuickTest testing process consists of 7 main phases:
Create your test plan
Prior to automating there should be a detailed description of the test including the exact steps to follow, data to be input, and all items to be verified by the test. The verification information should include both data validations and existence or state verifications of objects in the application.

Recording a session on your application
As you navigate through your application, QuickTest graphically displays each step you perform in the form of a collapsible icon-based test tree. A step is any user action that causes or makes a change in your site, such as clicking a link or image, or entering data in a form.

Enhancing your test
Inserting checkpoints into your test lets you search for a specific value of a page, object or text string, which helps you identify whether or not your application is functioning correctly.
NOTE: Checkpoints can be added to a test as you record it or after the fact via the Active Screen. It is much easier and faster to add the checkpoints during the recording process.
Broadening the scope of your test by replacing fixed values with parameters lets you check how your application performs the same operations with multiple sets of data.
Adding logic and conditional statements to your test enables you to add sophisticated checks to your test.
Debugging your test
If changes were made to the script, you need to debug it to check that it operates smoothly and without interruption.

Running your test on a new version of your application
You run a test to check the behavior of your application. While running, QuickTest connects to your application and performs each step in your test.

Analyzing the test results
You examine the test results to pinpoint defects in your application.

Reporting defects
As you encounter failures in the application when analyzing test results, you will create defect reports in Defect Reporting Tool.

What is spanning Tree?

What is spanning tree?
A spanning tree is a tree associated with a network. All the nodes of the graph appear on the tree once. A minimum spanning tree is a spanning tree organized so that the total edge weight between nodes is minimized.

queues needed to implement priority queue

Minimum number of queues needed to implement the priority queue?

Two. One queue is used for actual storing of data and another for storing priorities.

Datastructures used for recursion

Which Datastructure is used for recursion
Stack datastructure is used for recursion. Because of its LIFO (Last In First Out) property it remembers its ‘caller’ so knows whom to return when the function has to return. Recursion makes use of system stack for storing the return addresses of the function calls. Every recursive function has its equivalent iterative (non-recursive) function. Even when such equivalent iterative procedures are written, explicit stack is to be used.

Relocation of job interview

Relocation of job interview

So you have made it through the first few rounds of the interview process and you are now at the final stage of the interview. You are meeting the Hiring Manager and you know that everything is going great except you know that he/she is concerned about your willingness to relocate out-of-state for the position. How can you set his/her mind at ease concerning this alarming issue? Here, are our tips:

1. Write out a list of all your ties to the area. Before the interview, make a list of all the ties you have to the area or state. This list should include times you have visited or lived in the state. It should also include any family or friends that you have in the state.

2. Write out a list of all time you were away from home. Also, make a list of all the times you have been away from home. These can be to any location. Essentially, you are trying to make a record of times where you have been away from home for extended periods of time and were not homesick.

a. Examples could include going to a college out of state or going to Europe over the summer.

3. Research the city for more “useful” information. Research the city in which the job will be located. Make a list of the things that appeal to you about the city and how they would be a natural extension of you.

a. For example, if you do artwork on the side, talk in the interview about how great it would be to see “such and such” museum.

b. If you belong to any clubs or groups (avoid discussing any controversial groups) that have chapters in that area, state how
you look forward to joining those groups chapters.

c. Also, you can use the uniqueness of the city to your advantage as well. If you have never lived near the beach or the mountains, state how you are looking forward to a change from your own environment. If housing costs are cheaper, state this as well. Essentially, you are trying to show that a moving would be in your best interest.

4. Determine how your marital and family status will be benefit in the move. It is usually a no-no for the interviewer to ask you about these things. However, you can bring them up if you believe they will help your case. For instance, if you are single and have no children, you bring this point up to show that you can make this decision without consulting family. If you do have a family, you can state how your family supports your decision and would love to move there for such and such reasons.

5. Sell your commitment to the position. If this position would be an excellent learning opportunity or is with a very prestigious firm, state you would be more than willing to trade any small degree of homesickness because the benefits significantly outweigh this one minor issue.

6. Create a presentation for this interview question or concern. After you have compiled your research, you want to create a basic presentation that you will use when asked about this issue. By way of your preparation and your answer, you will be able to show you have thought about this issue and will give you a chance to state reasons why this will not be an issue and possibly even a benefit.

7. Take your cues from the interviewer. Try to gauge what specifically they are concerned about in your possible move and tailor your answer to that particular aspect. Often times, you can determine this by seeing how they respond to different parts of your answer to their question or what follow-up questions they ask you.

Implementing these steps will not guarantee the interviewer will be satisfied. However, it should go a long way towards planting seeds of thought that relocating will not be a significant issue. Your goal here is really to minimize any lingering doubts. If you are able to do effectively this, you just might be able to beat out a local candidate for the position.
