Writing your own header file

Writing your own header file: C: Data Structures, Pointers, and File Systems
Writing your own header file: C: Data Structures, Pointers, and File Systems

To create your own header file, place items from your source code, typically preprocessor directives but other definitions as well, into a separate file saved with the dot-h filename extension. Common items to include in a custom header file are function prototypes, constant expressions, macros, external variable declarations, typedefs, structure definitions, comments, and even other header files. When accessing a custom header file in C, use the include preprocessor directive but enclose the custom header in double quotes, not angle brackets.
