header-files

Which header files provide the intrinsics for the different x86 SIMD instruction set extensions (MMX, SSE, AVX, ...)? It seems impossible to find such a list online. Correct me if I'm wrong. fredoverflow <mmintrin.h> MMX <xmmintrin.h> SSE <emmintrin.h> SSE2 <pmmintrin.h> SSE3 <tmmintrin.h> SSSE3 <smmintrin.h> SSE4.1 <nmmintrin.h> SSE4.2 <ammintrin.h> SSE4A <wmmintrin.h> AES <immintrin.h> AVX <zmmintrin.h> AVX512 If you use just #include <x86intrin.h> it will include all SSE/AVX headers which are enabled according to compiler switches like -march=corei7 or just -march=native . Additionally some

Given this code sample: complex.h : #ifndef COMPLEX_H #define COMPLEX_H #include <iostream> class Complex { public: Complex(float Real, float Imaginary); float real() const { return m_Real; }; private: friend std::ostream& operator<<(std::ostream& o, const Complex& Cplx); float m_Real; float m_Imaginary; }; std::ostream& operator<<(std::ostream& o, const Complex& Cplx) { return o << Cplx.m_Real << " i" << Cplx.m_Imaginary; } #endif // COMPLEX_H complex.cpp : #include "complex.h" Complex::Complex(float Real, float Imaginary) { m_Real = Real; m_Imaginary = Imaginary; } main.cpp : #include

I installed Visual Studio 2010 Premium on my Windows 7 workstation. After loading a test C++ project, I noticed that it could not locate iostream. I took a look in C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\include and noticed that only two files exist here, srv.h and wmiatlprov.h I installed the VS2010 product on a test virtual machine, and this directory ( ...\VC\include ) is filled with the usual collection of folders and headers (the materials you'd expect to find in the includes directory.) I have taken the following steps to rectify the missing headers on the problem

I'm looking to create two classes, each of which contains an object of the other class type. How can I do this? If I can't do this, is there a work-around, like having each class contain a pointer to the other class type? Thanks! Here's what I have: File: bar.h #ifndef BAR_H #define BAR_H #include "foo.h" class bar { public: foo getFoo(); protected: foo f; }; #endif File: foo.h #ifndef FOO_H #define FOO_H #include "bar.h" class foo { public: bar getBar(); protected: bar b; }; #endif File: main.cpp #include "foo.h" #include "bar.h" int main (int argc, char **argv) { foo myFoo; bar myBar; } $ g+

Where could I find the list of all header files in C and C++? While I am building a library, I am getting an error like ' tree.h not found '. I suppose this is a standard header file in C and C++. This raised in me the curiosity to know all the header files and their contribution. Is there a place I can search for? I am working on Solaris Unix. Try here : http://en.cppreference.com/w/ However, you may also be refering to the header files of your OS. These can be found either on MSDN (Windows) or by man command (POSIX systems). Or another source if you're on another OS. The header 'tree.h' is

There are two path separators in common use: the Unix forward-slash and the DOS backslash. Rest in peace, Classic Mac colon. If used in an #include directive, are they equal under the rules of the C++11, C++03, and C99 standards? C99 says (§6.4.7/3): If the characters ', \, ", //, or /* occur in the sequence between the < and > delimiters, the behavior is undefined. Similarly, if the characters ', \, //, or /* occur in the sequence between the " delimiters, the behavior is undefined. (footnote: Thus, sequences of characters that resemble escape sequences cause undefined behavior.) C++03 says (
