recommended C++11 book

<r>QuoteOriginally posted by: katastrofaPolter, thank you a lot for your posts - they've been very informative and useful for me and will surely be for everyone who's looking to advance to C++11. (It took me a few evenings to go through all the related material and I still need to read more.)Could I...

char type in c++ dll and VBA

Never dealt with it. The Type way is how you'd call Windows APIs from VB. Would the SAFEARRAY way limit you to VC++?

char type in c++ dll and VBA

I'd be very surprised if you could pass a std::vector from C++ to VBA. You might be better off by passing a Type, these are easily convertible to POD C++ structs.

What development tools do you use?

This isn't my area but Amazon do provide scripts that you can use to build images and upload them to your instances.We don't compile our code on the instances but locally and make packages out of them (dpkg) that are then hosted on our own package repository.

What development tools do you use?

<t>I use QTCreator along with cmake for C++ dev on Linux. It's the closest thing to Visual Studio Linux has IMO.For debugging I just use gdb from the command line, all our production code runs on Amazon instances so that's a must-have skill really. Source control is all git with bitbucket, issue tra...

C++ quiz - Maths and acccuracy

<t>I was at an Intel conference a few days ago and there was a guy there who did CGI for films. He said they have to write their own maths libraries so that they get the same floating-point when they farm out work to their CPUs and GPUs. One little error can cascade down and ruin future image frames...

O(N)

<t>QuoteOriginally posted by: DominicConnorGood luck with your quest. I wonder if no one learns O(N) notation because today's computers are so much faster than those of yesteryear. For the kinds of low-N toy problems usually done in programming classes, the execution time is effectively 0. As GC and...

C++11 struct byte alignment

<t>QuoteOriginally posted by: outrunYes that was the new problem. I'm now using the swap snippet below, but can we also do it with std::swap? And is that faster?I've solved to initial problem with byte alignment and this endian stuff with "extractor functions" that accept a char* buffer and return a...

C++11 struct byte alignment

<t>QuoteOriginally posted by: CuchulainnNot my area these days and I have not looked into it but my 2 cents I would imagine that something like this? Does C++ 11 need to take care of endian differences? Endianness is a problem when a binary file created on a computer is read on another computer with...
