*. h or *. hpp for your C++ headers class definitions I use hpp because I want the user to differentiate what headers are C++ headers, and what headers are C headers This can be important when your project is using both C and C++ modules: Like someone else explained before me, you should do it very carefully, and its starts by the "contract" you offer through the extension hpp : C++ Headers
Whats the difference between C header files (. h) and C++ header files . . . hpp, H, etc is a loose convention for C++ header files, tcc is a loose convention for C++ template implementation, h is pretty strong convention for c files Boost uses hpp extension, QT uses h extension, STL do not have extension I am sure there are libraries which use H but have not seen any
c++ - . c vs . cc vs. . cpp vs . hpp vs . h vs . cxx - Stack Overflow hpp is an attempt to distinguish header files where there are significant C and C++ differences A common usage is for the hpp file to have the necessary cpp wrappers or namespace and then include the h file in order to expose a C library to both C and C++
whats the difference between hpp and hxx? - Stack Overflow 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
c++ - When to use . hpp files - Stack Overflow As mentioned in the comments hpp and h are essentially the same (for compiling c++, not c) If you are having problems linking your project it's not because of your file extensions In the header files you typically 'prototype' the class definition so that all of your class members can be used, not just ones defined before the current code
C++ templates declare in . h, define in . hpp - Stack Overflow Putting template definitions into hpp while other code into h seems to abuse the file extension Template code is usually all written in one header together with the template declaration, or in another header that may also be specially suffixed like tcc or something and then included into the header where the template declarations are put in
linux - c++ . hpp and . cpp - Stack Overflow Whether you have file hpp or file h is just a matter of preference Personally, I use hpp to indicate C++ rather than C In C++, unlike for example Java, classes in the global namespace are not public or private You can, however, hide or limit access to classes in various ways For example: Having them private in another class Using namespaces
c++ - What should go into an . h file? - Stack Overflow This is a pure style issue, but I believe that C++ declarations go in a hpp file while C declarations go into a h file This is very helpful when mixing C and C++ code (for example legacy modules in C) –
class - Splitting templated C++ classes into . hpp . cpp files--is it . . . @Abbas Yes, cpp cc etc must be avoided, but it's a good idea to use something other than hpp - e g tpp, tcc, etc - so you can reuse the rest of the filename and indicate that the tpp file, although it acts like a header, holds the out-of-line implementation of the template declarations in the corresponding hpp So this post starts with a good
