2015年9月2日 · But the reverse isn't true: you can't generally use a C++ header file in C code, so a convention of using the .hpp file extension makes it clear that it's a C++ header file and shouldn't be used by a C program. This naming scheme parallels the source file extensions: .c and .h for C, .cpp and .hpp for C++.

2021年7月12日 · .hpp is simply an alternative extension used for C++ headers as a matter of style. I personally prefer the use of .hpp as a file header because tools tend to interpret files with a .h extension as being a C header file and hence automatically choose the wrong syntax highlighting, auto-completion dictionary, etc.

2020年9月8日 · The .hh or .hpp files generally include common definitions you mIght want to #include in one or more .cpp or .hpp files. Doing so allows a build system like gnu make to figure out which cpp files to recompile when a .hpp file is modified.

2015年2月18日 · The solution to this duplication is to put all the descriptive information in another file, which we call a header file (nominally .h or .hpp.) With bar.h the information that needs to be included in foo.cpp and bar.cpp is only in one file, which is inserted into the file when the pre-processor finds the #include directive.

2014年11月8日 · Here, someone looking at the first few lines in the file can see that you are dealing with Texture objects in this file. This avoids issues where refactored headers cause compilation issues when they no longer require particular headers themselves. For instance, suppose you realize that RenderObject.hpp doesn't actually need Texture.hpp itself.

2022年12月15日 · I have a decently sizeable templated class. I would like to keep definitions in a separate file from the declaration, and found online suggestions to put them in a separate file that's included from the bottom of the .hpp file. The suggested file extensions were .tpp (for template cpp) or .inl (for inline).

2021年10月17日 · The .hpp file does NOT include the .cpp file. Inside my SA.cpp file, I have all the functions defined using a scope resolution operator. In addition, I #include "SA.hpp" file inside my SA.cpp file. The problem is that my code wont run if I simply added "#include SA.hpp" at the top. It isn't recognizing the function definitions inside my SA.cpp.

2018年7月11日 · What you omit to mention in #3 for the PROs is that fact the .tcc file (or .hpp in my case) typically will have more #includes than the .h with only declarations, thus it's not only reduced build times from direct-changes to .tcc/.hpp files, but also from indirect changes avoided by having fewer includes in the .h files. In large code bases ...

2014年8月24日 · The header file provides the declaration of the public interface. The header file defines what another implementation needs in order to use this interface. Information internal and private to this new interface do not (and should not) be declared in the header file. The public header file should be all anyone needs to use the module.
