address of array at index 2 0 (5/18/2013 6:58:48 AM) comp.lang.c++ hello group, i use the function std::inner_product(&arya[0], &arya[4], &aryb[0], 0.0f) with the c-style and/or c++11-style array. does the compiler set the addresses at compile time or is there a runtime... Chris

c++11 std::array init 2 2 (5/16/2013 7:02:43 AM) comp.lang.c++ hello group, why can i initialize a local std::array in this way: std::array locvar{1.0f, 2.0f, 3.0f}; but as member "only" in this way: std::array member{{1.0f, 2.0f, 3.0f}}; i use mingw g++ 4.8... Chris

lambda recursion 14 2 (4/28/2013 4:00:07 PM) comp.lang.c++ hello group, can a lambda function call itself for recursion purposes? thanks for answering! cheers, chris ... Chris

const local vs. member 17 4 (4/25/2013 11:43:31 AM) comp.lang.c++ hello group, what do you think/know is faster: Matrix& Matrix::Translate(GLfloat x, GLfloat y, GLfloat z) { const std::array translate = { 1.0f, 0.0f, 0.0f, 0.0f, 0.0f, 1.0f, 0.0f, 0.0f, 0.0... Chris

std::move in methode 7 13 (3/28/2013 9:12:50 AM) comp.lang.c++ does the std::move() assignement make sense here or is it used only in ctors? void Matrix::Ortho(GLfloat right, GLfloat top, GLfloat near, GLfloat far) { std::array temp = { 1.0f / right, 0.0f, 0.0... Chris

std::array clear 8 14 (3/26/2013 1:21:49 PM) comp.lang.c++ is it guaranteed, that std::array, 4> var = {}; sets all 16 values to 0.0f? thanks, chris ... Chris

static/local array 1 9 (1/10/2013 9:03:47 AM) comp.lang.c++ hello, i have some strange behavior in my multithreaded app. i do some matrix-multiplications in a methode. if i use local arrays there it works, but if i use a static member array (some kind of reusable... Chris

enum class 2 16 (12/17/2012 10:56:31 AM) comp.lang.c++ is it possible to use enum class as index in std::vector or std::valarray without explicit conversation? ms vs express 2012 do not compile something like: enum class Coordinate : std::size_t { X, Y, Z };... Chris

observer pattern error (is not captured) 2 28 (11/12/2012 11:06:21 AM) comp.lang.c++ hello group, in my subject-methode detach(const observer& o) i used following line to remove the observer: observers.remove_if([](MyObserver mo){ return &o == &mo; }); gcc 4.7 (mingw) give me the err... Chris

C++11 Threads 2 21 (11/5/2012 10:18:43 AM) comp.lang.c++ hello group, im working on an app and have two (ok more) questions: 1) i want to sync my pgm-logic to its "natural" periode: the vertical retrace of the monitor. i do this with a function named eglSwap... Chris

Initialization and Memory 7 30 (6/12/2012 5:35:32 AM) comp.lang.c++ Hello, if i write code like this: #include int main() { float big[] = { 1.0f, 2.0f, 3.0f }; std::vector v(big, big + sizeof(big) / sizeof(big[0])); } are the floats twice ... 4one (114)
