I mean other than using it when required for functions, classes, if, while, switch, try-catch. I didn't know that it could be done like this until I saw this SO question. In the above link, Eli mentioned that "They use it to fold up their code in logical sections that don't fall into a function, class, loop, etc. that would usually be ...
What's an easy to use SNMP client library for c++? ...
I have two C++ processes (A and B), executing under Windows, where one launches the other. I would like to effectively single-thread their execution. For example: Start process A A creates B A suspends B executes some fixed set of operations B suspends and A is resumed A executes some fixed set of operations A suspends and B is resumed...
I've heard of "error" when using floating point variables. Now I'm trying to solve this puzzle and I think I'm getting some rounding/floating point error. So I'm finally going to figure out the basics of floating point error. What is a simple example of floating point/rounding error (preferably in C++) ? Edit: For example say I have...
OK, I have a somewhat complicated system in C++. In a nutshell, I need to add a method to a third party abstract base class. The third party also provides a ton of derived classes that also need the new functionality. I'm using a library that provides a standard Shape interface, as well as some common shapes. class Shape { public: ...
I have checked with the wikipedia article, and it seems like it is missing the c++ version of a code example. I am not able to fully appreciate the Facade pattern without this, can you please help explain it to me using C++? ...
At the moment I am working in a pretty big project and I have been been asked to refactor some old code. Most of the refactoring is setting apart a big class into smaller components and functions. I've searched and seen some other questions related with the topic but I am not very happy with the proposed options. The problem with these ...
As the title says, I have a Windows app written in C++ from which I need to make calls to remote Thrift services, and I'm a bit lost on the subject, to be honest. http://wiki.apache.org/thrift/ThriftInstallationWin32 states that "The Thrift C++ runtime library does not currently work on Windows". Does that mean I'm shit out of luck, or i...
C++: Since a struct is a class with everything "public", are default -ctors created and called? The reason I ask is to understand the overhead, if any, that C++ may have over C, when structs are used. An opinion I have heard is that classes have some overhead that structs don't, in C++, but I question this. ...
Hi, I'm trying to code opposite action to this: std::ostream outs; // properly initialized of course std::set<int> my_set; // ditto outs << my_set.size(); std::copy( my_set.begin(), my_set.end(), std::ostream_iterator<int>( outs ) ); it should be something like this: std::istream ins; std::set<int>::size_type size; ins >> size; s...
I'm trying to write a software synthesizer that recreates the sounds made by classic synthesizers like the Moog and the DX7. Does anyone know of any code resources for something like this? Thanks. ...
I stumbled several times over D and really asked myself why it isn't more popular. D is a systems programming language. Its focus is on combining the power and high performance of C and C++ with the programmer productivity of modern languages like Ruby and Python. Special attention is given to the needs of quality assurance, document...
My company, a C++ house, is always looking to hire recent grads. However due to the Java Schools phenomenon, we typically end up interviewing strong Java programmers with maybe a minute smattering of C++. Often the C++ classes don't really prepare students for working in C++. Nevertheless, often these are bright kids, eager to learn and ...
In C++, a function's signature depends partly on whether or not it's const. This means that a class can have two member functions with identical signatures except that one is const and the other is not. If you have a class like this, then the compiler will decide which function to call based on the object you call it on: if it's a cons...
Hi there, I am looking for an easy way to get the SID for the current Windows user account. I know I can do it through WMI, but I don't want to go that route. Apologies to everybody that answered in C# for not specifying it's C++. :-) ...
So let's say I have two different functions. One is a part of the BST class, one is just a helper function that will call on that Class function. I will list them out here. sieve(BST<T>* t, int n); this function is called like this: sieve(t,n) the object is called BST t; I'm going to be using the class remove function within the...
I want to have a map that has a homogeneous key type but heterogeneous data types. I want to be able to do something like (pseudo-code): boost::map<std::string, magic_goes_here> m; m.add<int>("a", 2); m.add<std::string>("b", "black sheep"); int i = m.get<int>("a"); int j = m.get<int>("b"); // error! I could have a pointer to a base ...
Is it possible to typedef long types that use templates? For example: template <typename myfloat_t> class LongClassName { // ... }; template <typename myfloat_t> typedef std::vector< boost::shared_ptr< LongClassName<myfloat_t> > > LongCollection; LongCollection<float> m_foo; This doesn't work, but is there a way to achieve a si...
Hi everybody, I need to store my class A objects in some data structure. In addition, i would like them to be automatically sorted according to a key, which is in my case an embedded object of another class B. Thus I decided to use a STL priority queue. However it is possible that the 2 or more objects B to have the same key value. ...
Or does it? Should an object-oriented design use a language construct that exposes member data by default, if there is an equally useful construct that properly hides data members? EDIT: One of the responders mentioned that if there's no invariant one can use a struct. That's an interesting observation: a struct is a data structure, i....
