You can include the contents of other files within the source file
prior to compilation by using the #include directive.
Description |
 |
The #include preprocessing directive causes HP C++ to
read source input from the file named in the #include directive.
Usually, include files are named:
If the file name is enclosed in angle brackets (< >), the system
directory is searched to find the named file. If the file name is
enclosed in double quotation marks ("), HP C++ searches
your current directory for the specified file. Refer to "System
Library and Header Files" in Chapter 3 “Compiling and Executing HP C++ Programs” for a detailed description
of how an #include file is found.
Files that are included may contain #include directives themselves.
HP C++ supports a nesting level of at least 35 #include files.
The arguments to the #include directive are subject to macro replacement before the directive processes them. Thus, if you use
an #include directive of the form #include identifier, identifier
must be a previously defined macro that when expanded
produces one of the above defined forms of the #include directive.
Refer to the next section, "Macro Replacement," for more information
on macros.
Error messages produced by HP C++ indicate the name
of the #include file where the error occurred, as well as the line number within the file.
