header files in C++

[SukhdeepMankoo]

I have seen header files in c++ are without *.h extension.while extension is preserved in c. why need to declare header files without any *.h extension? what will its benefit.

Thanks

Though .hpp is used in some of the modern C++ environments, .h is inherited and still used under C++. So practically you can use either .h or .hpp for header files under C++. But I don't think the extension of the header file matters at all as those are not getting compiled (Just added to the source file where #include directive appears).

However, you will have to use .CPP for C++ source files since C/C++ compilers mostly detect the compilation method based on the extension.

Thanks.
But i have also seen header file, where it does not have any extension.what abt that? why header files do not carry any extension.

That's alright. As said before, when you put the #include directive, the header file will be placed on your source file, that's all. So it can have any extension or no extension at all.
