What is header file in c program and its uses

A header file has the suffix. h and includes C function declarations and macro definitions that may be reused across several source files. The files that the programmer creates and the files that arrive with your compiler are the two sorts of header files.

A header file’s main function is to ensure that declarations are propagated to code files. We can put declarations in one place and then import them anywhere we need them via header files. In multi-file apps, this may save a lot of typing.
