Understanding Header Files in C

We all use header files in C, but what are they? They are files that hold the declaration of functions and constants that we can use in our main code. The declared functions still need to be defined compiled. In C the headers file has just the declaration and it is the source file that has the definition. If it is not in source then the definition must be in a library file that is already compiled and  accessible on your system.  For example the stdio.h will link to the glib.c module. Using both an IDE and the command line we explain how the linking works
