2. c++ - *.h or *.hpp for your class definitions - Stack Overflow

   stackoverflow.com/questions/152555

   In conventional use (by boost, etc), .hpp is specifically C++ headers. On the other hand, .h is for non-C++-only headers (mainly C). To precisely detect the language of the content is generally hard since there are many non-trivial cases, so this difference often makes a ready-to-use tool easy to write.

3. c++ - .c vs .cc vs. .cpp vs .hpp vs .h vs .cxx - Stack Overflow

   stackoverflow.com/questions/5171502

   .hpp is an attempt to distinguish header files where there are significant c and c++ differences. A common usage is for the .hpp to have the necessary cpp wrappers or namespace and then include the .h in order to expose a c library to both c and c++.

4. what's the difference between hpp and hxx? - Stack Overflow

   stackoverflow.com/questions/1862658

   In C++, the file extension doesn't actually matter. The use of .h, .hpp, .hxx, or no file extension are all by convention. The standard library uses no file extension for its header files. Many projects, including Boost, use .hpp. Many projects use .h. Just pick one and be consistent in your project. answered Dec 7, 2009 at 20:26. James McNellis.

5. What is the difference between a .cpp file and a .h file?

   stackoverflow.com/questions/875479

   The .cpp file is the compilation unit: it's the real source code file that will be compiled (in C++). The .h (header) files are files that will be virtually copied/pasted in the .cpp files where the #include precompiler instruction appears. Once the headers code is inserted in the .cpp code, the compilation of the .cpp can start.

6. c++ - Creation of hpp file in Visual Studio - Stack Overflow

   stackoverflow.com/questions/19112553

   1. .h is a perfectly valid alternative for .hpp. It's just an extension for a header, it doesn't mean it's c. Your compiler will treat this file the same way no matter whether the extension is .h or .hpp. Yet if for some reason you still need .hpp extension, just click New Item ~> Header File (.h) and at the bottom name it with .hpp extension.

7. c++ - Why have header files and .cpp files? - Stack Overflow

   stackoverflow.com/questions/333889

   The first is the compilation of "source" text files into binary "object" files: The CPP file is the compiled file and is compiled without any knowledge about the other CPP files (or even libraries), unless fed to it through raw declaration or header inclusion. The CPP file is usually compiled into a .OBJ or a .O "object" file.

8. c++ - What should go into an .h file? - Stack Overflow

   stackoverflow.com/questions/1945846

   Header files (.h) are designed to provide the information that will be needed in multiple files. Things like class declarations, function prototypes, and enumerations typically go in header files. In a word, "definitions". Code files (.cpp) are designed to provide the implementation information that only needs to be known in one file.

9. c++ - Visual Studio 2012: 'opencv2/opencv.hpp' : No such file or...

   stackoverflow.com/questions/21500725

   Open Visual Studio and create a new project. On “Solution Explorer”: Right click on the project title and then go to “Properties”. Change Platform to “x64”. Go to “C/C++” -> “General” -> “Additional Include Directories” and add (without quotation marks) “C:\opencv\build\include”. Click on “Apply”.

    stackoverflow.com/questions/41087485

    int getX(); foo.cpp: return x; main.cpp: Foo f(10); return 0; Keep your variables private and make functions like getX() const. Possible large class declaration / implementation using more techniques (static, move semantics): foo.hpp:

11. Fatal error: SFML/Graphics.hpp: no such file or directory exists

    stackoverflow.com/questions/33071296

    go to project -> properties. set configuration and platform to all platform then: in c/c++ -> aditional include directories -> path to your include folder inside your sfml folder. in linker -> general -> adiotional lib raries directories -> path to your lib folder inside your sfml folder.
