What are header files in C++ ( PROGRAMMING TUTORIAL for beginners)

C++ header files are files that usually have .h extensions and they contain declarations of variables, functions... The implementation of those functions goes into the implementation file. By doing this, if the implementation does not change, there is no need to recompile the implementation file, which would not be possible if everything was in one file. This also gives us the option to reuse the functions that are declared in the header file in multiple .cpp files. In order to do that you just need to include the corresponding header file in the .cpp file that wants to use those functions. In this C++ programming tutorial, you will learn what are header files, how to create your own header file, and how to include it and work with it. ?
