Thread: Want to put Functions in another source file

I am starting a basic animation program using direct x. The functions of it, I want to put in another source file or header file to make the program as short as possible for readability purposes.


I don't know how to make a header.
Is it as simple as putting the functions in another source file?

Do I need to use the extern command in my code somewhere?

thanks

just wish I could save the web page. It keeps telling me that it can't save to the specified location.
