What is the .HXX File Extension?

.HXX File Extension Description:

The file extension HXX is a C++ Header file. In programming language, particularly in C++ and C programming languages, the header file, which is also known as an include file is stored with HXX file extension. This file is in the source code form. Since it is a source code, the file with the .hxx file extension is included in the compiler, which is another source file that automatically includes it. The header files are included automatically through a compiler directive at the head, or at the beginning of other source files.

The file using the HXX file extension or the header file has forward declarations of variables, subroutines, and other identifiers required in the programming language of C and C++. The identifiers that are necessary to be declared in more than a source file may be situated in a single header file that is then incorporated in the event that what it contains is needed. In the programming languages C++ and C, the standard library functions are generally declared in the header files such as the HXX file extension.

The files with HXX file extension also include patterns. Even when C programming of the header is done, some complex software still requires the header file management carefully. When C has progressed to C++, the management of the files in the HXX file extension also became more time consuming, due to it becoming much complex, as well.

There are rules to be followed for header file inclusion. Included in the rules is that a header file is only to be included when the forward declaration cannot do the job. The file in HXX file extension needs to be designed so that the order of the file is not deemed important. Moreover, the mechanism for the file inclusion must be allowed for the duplication of the inclusion of the header file.
