While you're in such a good mood, you should gently help out "jirigala" (user #98406) who posted the same question in all these articles

Probably more too, but the web service only shows 10 threads. Wink | ;)

You're doing a great job of it, and (I hope) setting a good example for the rest of us.

I've talked a lot about the danger we have of becoming insular, and I'm trying to act in accordance with what I have said

That's a great danger to a site that is growing at the pace CP is experiencing, and a pitfall that we need to avoid. Those of us who have been around since the beginning are bound to feel threatened by the changes, but we need to grow with them, not oppose them. It's not the same elite club it used to be, and we need to adapt accordingly.

But who hasn't posted something inappropriate somewhere as a newbie ?

We all have, I think. My one and only article, so far, was posted only out of a feeling of obligation to contribute something to the site that has given me so much. It's relatively worthless, but it solved a problem my employer needed solved, and it was all I had on tap to offer at the time. I hope that someone else has found it useful, but I strongly doubt it. If my submittal had been met with ridicule and abuse, however, I would have never visited again. We need to keep that in mind when we find a newbie in our midst - we don't want to run off any gems in the rough, and the trend lately has been rather hostile.

to feel smug that I showed them who is boss.

Yeah, I know the feeling... It's fun, but transitory. Better, much I think, to suffer in silence a few youthful indiscretions, than to lose a potentially valuable member of our community.

Thanks, again, for setting a standard I'd like to emulate...

That is one of the most comprehensive and gentle responses I have ever seen on this site to a "please do my homework for me" question

Maybe Chris should add an option under each thread near [Reply], like [Homework], which would automatically reply an answer like the one Christian wrote.

1) A gas station has two pumps. Cars arrive at an average rate of 24 per hour. The service time for each car is either 3,4,5,6, or 7 minutes each with probability 1/5. Simulate the operation of the gas tation for 8 hours using a one minute time interval. Assume that a car arriving when both pumps are occupied drives on. Determine and print out the fraction of customers lost, in addition to the number of customers served and the total number of arrivals during the 8 hour period.

Looks like a pretty simple problem - where are you stuck ?

No offense, but I don't really want to encourage the creation of another VB developer. - Larry Antram 22 Oct 2002

Hey, at least Logo had, at it's inception, a mechanical turtle. VB has always lacked even that... - Shog9 04-09-2002

Again, you can screw up a C/C++ program just as easily as a VB program. OK, maybe not as easily, but it's certainly doable. - Jamie Nordmeyer - 15-Nov-2002

This is a forum for ppl wanting solutions for Visual C++. Not to answer something that looks like as if it was copied straight from an assignment sheet.

If it was an assignment or test.. shame on you.

Re: Arithmetic Error Handling

Pardon me if this is trivial, but I haven't had to implement this before...

I have a 64-bit value represented by a struct comprised of two DWORDs, a low part and a high part. I want to add an offset to it, and my first thought was to simply add the unsigned long offset to the low part, then check the result; if the result is lower than the original value, then an overflow occurred, and I need to increment the high part to implement the carry. I'm told, however, that C++ doesn't work that way - the result will be undefined. I've tried a couple of dodges, one being to create an accumulator to concatenate the two DWORD values into a single 64-bit value and perform the addition on that entity, but the compiler hasn't a clue what I mean by that, and complains loudly.

What is the proper way to accomplish this addition?

use "unsigned __int64" for the math, then break it apart when you need to store it?
