Does the input and output routine have to be in a sub-routine? If not, why not have the loop in the main program. Then you could do the file output loop the same way you output Name on line 41 (and...

I notice you open the output file twice: once at line 20 and then again at 33. Perhaps delete line 20.

And your sub-routine abc uses cout to output to the console, but does not output to the...

MATLAB has an "area" function, but I think it requires a known function, which doesn't help you, since your data is experimental.

I am not aware of MATLAB having the sort of function you want,...

I recently upgraded to the latest version of Firefox (3.5.1) and now my highlighting is all messed up.

To speed up finding a term in a web page, I usually do a Control-F, enter the term for...

Hello, all.

The company that hosts my web site does no filtering of spam or viruses whatsoever. Whatever is sent to me, I get. They have indicated that most of their clients are companies that...

True. That is so results can be repeated. For example, if you are using random numbers to fill a matrix for some program you are debugging, you would like the data to be the same each time you re-run...

To be thorough, you should also wrap the allocation in a try-block and have a catch-block so that, if an exception occurs, it can be properly dealt with.

What, exactly, doesn't work? The input portion?
Once you input the data, have you outputted it to check if it is wrong or right?

Perhaps you could post the code you have already written, to give...

Tonight (Thursday, November 27) I noticed most lounges are missing.

The only one I see listed is the Geeks' Lounge. However, at the top of the page, I still saw a reference to the other lounges:...

In my web surfing, I often come across mention of SourceForge in the Geek Community. I am wondering: what exactly is SourceForge and why is it so popular?

I back up important documents on a USB...

I haven't done much looking, Computational Fluid Dynamics is a pretty specialized topic; however, off the top of my head, I would suggest you check out CFD Online (http://www.cfd-online.com/).

I stand corrected.

Previously, I had only seen Newton's Method covered in sections of textbooks dealing with finding real roots. However, I have since done some further investigating, and found...

I agree: the fourth root of a number, x, is sqrt(sqrt(x)), or pow(x, 0.25).

Hi, everybody.

I have noticed that there are a lot of forums on the Internet. Many of them have the same themes and cover the same material that is covered on bigger sites (like DaniWeb). So now I...

I don't think Newton's Method can be used to find complex roots. The same goes for the Bisection Method and the Secant Method--all these methods are only applicable for finding roots that you know...

What functions would you like to convert? Numerical programming is one of my hobbies; I might be able to refer you to some relevant resources.

Hi, folks.

For those of you whose websites get significant traffic, I am wondering if there was one particular event that you consider to be a breakthrough? For example, was it a mention in a...

I usually code all my Javascript in a single external file that accepts the data from a form in the main page's HTML textarea box.

Now I would like to break up this single Javascript file into...

I would think that registering in forums just to create a profile with a hyperlink and then not posting in the forums would not be worth the effort.

Nobody would even know you exist on a forum...

Hi, everybody.

I am thinking about upgrading from my existing DVD player to a new Blu-ray disc player. However, I am wondering if it is as simple as just purchasing the player. I don't want to...

Hi, everybody.

A question I have had for a while regarding forums is if there is some way to configure an alert to be e-mailed to me for specified keywords.

I don’t know everything about...

For what purpose will these numbers be used?

If they are just going to be dummy numbers to fill an array for the testing of a program, rand() should do fine. If you want numbers within a certain...

Hello, everybody.

Out of the blue I recently received an e-mail from somebody who would like to put a text ad on my website. This is the first such offer I have received, and I have no idea how to...

Hi, everybody.

I am looking for advice from veteran webmasters--those who have successfully made money on the Internet.

To me, it seems like the main ways to make money from a website are...

Hi, folks.

I am wondering if anybody in this forum is in, or going to, Vienna, Austria? (With over 200K members, I hope somebody in this forum can reply)

It may sound like a silly request, but...

The biggest sites (like delicious) don't pass on PR. However, following are a couple lists you might find helpful. The first one is a list of bookmarking sites that pass on PR, so they help your site...

Have you also checked out Alt-N Technologies (http://www.altn.com/)? I believe they have scalable options (i.e. - they offer webmail software products that depend upon the number of users. Of course...

On a related note:
one nice feature of DP is that they have a sub-forum specifically for the introduction of new directories. Every day you can visit this forum and there seems to be at least five...

I think writing your own webmail software would be too much hassle.

Are you sure there is nothing else presently available that might serve your purpose? I know of several webmail services in...

I checked it out and everything seemed to work fine.
Didn't notice any spelling or grammar errors.
No weird behaviour.

Like you indicated, it is kind of plain at the moment, but definitely a...

None of the search engines I know about require you to put their logo on your site just to submit your site to them.

Perhaps you are actually thinking about submitting to directories. Many of them...

I have used a free tracker from Extreme Tracking before and found that to be acceptable:

I am no expert in MATLAB, but I would find it helpful to see more of your code, specifically, the declaration of A.

Hi, folks.

I have written some pretty complicated programs in Javascript (in terms of the code itself), but I haven’t experimented much with the nuts-and-bolts of Javascript. In particular, I have...

Hi, folks.

I am about to start exploring a field I haven't bothered with up to now: Internet TV. I do not have cable television (not even a basic service), but I do have a high-speed Internet...

Hello, gurlmystique.

Welcome to DaniWeb. I am sure you will find these forums an excellent resource. You mentioned interacting with people of similar interests. What are your interests and...

Yes, such programs can be made. In fact, programs already exist which do definite integration. Some take a given function that cannot be solved analytically and solve it numerically over a specified...
