C Header Files

Posted by Guy Lecky-Thompson Jun 9, 2006

Continuing the beginners C programming course, this week we look at the C header file.

Breaking up some programming task into individual source code files is standard practice. One file simply cannot contain manageable code to perform anything but the simplest of functions.

The C header file interface allows us to specify what these functions look like, so that the compiler can compile each file individually. It also provides interfaces to third party and standard libraries.

For more information on how to use header files in the c programming language, please take a look at the C tutorial articleC Hedaer Files.
