Hello, Over the last couple of months I've been working on some implementations of sockets servers in C++ and Java. I wrote a small server in Java that would handle & process input from a flash application hosted on a website and I managed to successfully write a server that handles input from a 2D game client with multiple players in C...
I'm getting this warning all over the place in some perfectly well functioning objective-c code within XCode. My google-fu has failed me... others have run into this but I could not find an explanation on what exactly is causing it or how it can be fixed. ...
Today I got into a very interesting conversation with a coworker, of which one subject got me thinking and googling this evening. Using C++ (as opposed to C) in an embedded environment. Looking around, there seems to be some good trades for and against the features C++ provides, but others Meyers clearly support it. So, I was wondering w...

Hi stackoverflowers is there any way to build/run small C++ programs, in Visual Studio without creating projects, like in old days in IDEs like turbo c++ you could just compile and run without creating projects. Thanks in advance! ...
Dear StackOverFlowers, I will be parsing 60GB of text and doing a lot of insert and lookups in maps. I just started using boost::unordered_set and boost::unordered_map As my program starts filling in these containers they start growing bigger and bigger and i was wondering if this would be a good idea to pre allocate memory for these c...
I'd like to emulate violent system shutdown, i.e. to get as close as possible to power outage on an application level. We are talking about c/c++ application on Linux. I need the application to terminate itself. Currently i see several options: call exit() call _exit() call abort() do division by zero or dereference NULL. other option...
Hi all, Why do we say language such as C is top-down while OOP languages like java or C++ as bottom-up?. Does this classification has any importance in software development? Thanks. ...

Is it necessary to check for nullptr after allocating an object using gcnew? ...
I am looking to get into operating system kernel development and figured my contribution would be to extend the SANOS operating system in order to support JDK 1.6 and 1.7. I have been reading books on operating systems (Tannenbaum) as well as studying how BSD and Linux have tackled this challenge but still am stuck on several concepts. ...

Hello, if I compile (under G++) and run the following code it prints "Foo::Foo(int)". However after making copy constructor and assignment operators private, it fails to compile with the following error: "error: ‘Foo::Foo(const Foo&)’ is private". How comes it needs a copy constructor if it only calls standard constructor at runtime? #i...

I was just made aware of a bug I introduced, the thing that surprised me is that it compiled, is it legal to switch on a constant? Visual Studio 8 and Comeau both accept it (with no warnings). switch(42) { // simplified version, this wasn't a literal in real life case 1: std::cout << "This is of course, imposible" << std:...
