- Should I include lt;xxxx. h gt; or lt;cxxxx gt; in C++ programs?
-1 re "we are not polluting the global namespace", you have just quoted and discussed that this is not the case so a bit of self-contradiction it is important because it directly affects the conclusion of what is best practice your conclusion above is wrong it is weird you first discuss why it's a bad choice (possibility of code not working across compilers, unintended namespace
- c++ - #include in . h or . c . cpp? - Stack Overflow
In callback h you should include everything needed to compile against it But nothing more But nothing more Consider whether using forward declarations in your header file (such as class GtkButton; ) will suffice, allowing you to reduce the number of #include directives in the header (and, in turn, my compilation time and complexity)
- Why are #ifndef and #define used in C++ header files?
The cost of opening a file, discarding all its contents, and closing it over and over might not sound like much, but for a large header included transitively by hundreds of other headers (e g windows h, the low-level stuff providing simple type definitions like stdint h, types h, etc ), the difference between opening it exactly once per source file and opening it a hundred times (where only
- Creating your own header file in C - Stack Overflow
You want to place #ifndef #defines around your h code so that if you include the same h twice in different parts of your programs, the prototypes are only included once client h #ifndef CLIENT_H #define CLIENT_H short socketConnect(char *host,unsigned short port,char *sendbuf,char *recievebuf, long rbufsize); #endif ** CLIENT_H *
- c++ - . c vs . cc vs. . cpp vs . hpp vs . h vs . cxx - Stack Overflow
* h or * hpp for your class definitions What is the difference between cc and cpp file suffix? I used to think that it used to be that: h files are header files for C and C++, and usually only contain declarations c files are C source code cpp files are C++ source code (which can also be C source code)
- c - What mean file with extension h. in? - Stack Overflow
Typically, a h in file is a header template that is filled in to become the actual header by a configure script based on the outcome of several tests for features present on the target platform Share
- *. h or *. hpp for your C++ headers class definitions
another convention is to use h for C headers and hpp for C++; a good example would be the boost library Quote from Boost FAQ, File extensions communicate the "type" of the file, both to humans and to computer programs The ' h' extension is used for C header files, and therefore communicates the wrong thing about C++ header files
