stl function adapter to compare struct member
I've wondered if I'm missing something when I do searches in stl collections, to find an element that has a member that has a certain value. I don't want to have to write any special function object or accessor function, there should be a function adaptor that takes a member pointer (not a member function pointer.... 13 Jun 2010 06:07

Member Initialization Lists
One of many questions I typically ask candidates who come to interview with me is this one: class A { public: A() : y(2), x(y * 2) {} ~A() {} private: int x; int y; }; int main() { A a; return 0; } I ask them what the value of a.x and a.y will be after 'a' has been constructed. ... 15 Jun 2010 04:20

Templates rejected on non-dependent parameters before deduction in C++0X?
(I attempted to post this to comp.std.c++ but it didn't seem to pass moderation, so I thought this is a 2nd best location) While doing some meta-programming for choosing a return type of an overloaded function, I ran into a problem with the expansion of templates in the return type of overloaded functions (that a... 10 Jun 2010 21:15

A quick question about Initializer-List in C++0x
Hi Everybody! I just tried to compile the following with gcc-4.5 in c++0x mode: int main (int argc, char* argv[]) { std::map<std::string, std::vector<std::string>> m { {"Hello", {"Good", "World"}}, {"Goodbye", {"Rude", "World"}} }; return 0; } However I get compilation errors when I d... 9 Jun 2010 14:11

Critique of code quality

How to reuse an existing stream with a different streambuf ?
Hello, Some days ago, I decided that it would be fun to write a `streambuf` subclass that would use `mmap` and read-ahead. I looked at how my STL (SGI) implemented `filebuf` and realized that `basic_filebuf` contains a `FILE*`. So inheriting from `basic_filebuf` is out of the question. So I inherited from `ba... 8 Jun 2010 13:41

VisualC++ vs GCC: read in a number in exponential notation
Dear all! I'm writing a fairly simple program interpreting an input with numbers in exponential notation. I have encountered a problem in MS VisualC++ 2008 Express Edition which is illustrated in the following code: #include <iostream> #include <string> #include <sstream> using namespace std; int main()... 10 Jun 2010 21:15

Static variable in template function
Hi all, the following function writes n bits data to file. Parameter named 'Data' contains the value to be written, 'Length' contains the number of bits of 'Data' to write. This function uses a static buffer named BitBuffer to store bits between calls. When BitBuffer is full it is written to file. void Writ... 9 Jun 2010 00:59
