8: A header file is a file of C code that contains definitions, dec-
9: larations, and structures commonly used in a given situation. By
10: tradition, a header file always has the suffix ``.h''. Header
11: files are invoked within a C program by the command #iinncclluuddee,
12: which is read by cpp, the C preprocessor; for this reason, they
13: are also called ``include files''.
14:
15: Header files are one of the most useful tools available to a C
16: programmer. They allow you to put into one place all of the in-
17: formation that the different modules of your program share.
18: Proper use of header files will make your programs easier to
19: maintain and to port to other environments.
