Usually, when you get a lot of pre-processor directives, or you have a large program with several source code files, you can abbreviate your code and eliminate redundancies by creating your own header file. For example, here is the same silly code but with several of the items removed. Instead, you see a single include directive at line 1 with a file name in double quotes.
