I've tried several things already, std::stringstream m; m.empty(); m.clear(); both of which don't work.

I want to expand my programming horizons to Linux. A good, dependable basic toolset is important, and what is more basic than an IDE? I could find these SO topics: Lightweight IDE for linux and What tools do you use to develop C++ applications on Linux...

We have the question is there a performance difference between i++ and ++i in C? What's the answer for C++?

I'm trying to learn C. As a C# developer, my IDE is Visual Studio. I've heard this is a good environment for C/C++ development. However, it seems no matter what little thing I try to do, intuition fails me. Can someone give good resources for how to eithe...

I have been reading through the C++ FAQ and was curious about the friend declaration. I personally have never used it, however I am interested in exploring the language. What is a good example of using friend? Reading the FAQ a bit longer I like the ...

I develop C++ applications in a Linux environment. The tools I use every day include Eclipse with the CDT plugin, gdb and valgrind. What tools do other people use? Is there anything out there for Linux that rivals the slickness of Microsoft Visual Studi...

I'm trying to parse an INI file using C++. Any tips on what is the best way to achieve this? Should I use the Windows API tools for INI file processing (with which I am totally unfamiliar), an open-source solution or attempt to parse it manually?

I come from a Java background, where packages are used, not namespaces. I'm used to putting classes that work together to form a complete object into packages, and then reusing them later from that package. But now I'm working in C++. How do you use name...

For whatever reason, our company has a coding guideline that states: Each class shall have it's own header and implementation file. So if we wrote a class called MyString we would need an associated MyStringh.h and MyString.cxx. Does anyone else do thi...

I've been writing C and C++ code for almost twenty years, but there's one aspect of these languages that I've never really understood. I've obviously used regular casts i.e. MyClass *m = (MyClass *)ptr; all over the place, but there seem to be two othe...

I want to know what a "virtual base class" is and what it means. Let me show an example: class Foo { public: void DoSomething() { /* ... */ } }; class Bar : public virtual Foo { public: void DoSpecific() { /* ... */ } };

In the C and C++ programming languages, what is the difference between using angle brackets and using quotes in an include statement, as follows? #include <filename> #include "filename"

So far, I've only used Rational Quantify. I've heard great things about Intel's VTune, but have never tried it! Edit: I'm mostly looking for software that will instrument the code, as I guess that's about the only way to get very fine results. See als...

I'm looking for a method, or a code snippet for converting std::string to LPCWSTR

VC++ makes functions which are implemented within the class declaration inline functions. If I declare a class Foo as follows, then are the CONSTRUCTOR and DESTRUCTOR inline functions? class Foo { int* p; public: Foo() { p = new char[0x00100000...

I would like to call python script files from my c++ program. I am not sure that the people I will distribute to will have python installed. Basically I'm looking for a .lib file that I can use that has an Apache like distribution license.

What would be the most efficient way to compare two double or two float values? Simply doing this is not correct: bool CompareDoubles1 (double A, double B) { return A == B; } But something like: bool CompareDoubles2 (double A, double B) { diff...

Maybe this is a dumb question, but is there any way to convert a boolean value to a string such that 1 turns to "true" and 0 turns to "false"? I could just use an if statement, but it would be nice to know if there is a way to do that with the language o...

Basically I want tools which generate source code visualization like: function call graph dependency graph ...

How do you set, clear, and toggle a bit?
