C: Why do we include header files, which declare but don't define?

Question

Answer 1

The header files with a .h extension only includes the declarations of the functions. Its actual implementation is mentioned in a separate .c file. It is the .h file that further includes the .c file which is present in the .h file's local directory . Things will be even clearer if you try to do a project on compilers where you create your own header files
