grandparent files. Thus, searching begins relative to the directory containing the source currently Notes
being processed. If the file is not found, the search moves to directories specified by the /I compiler
option. Finally, the directories specified by the INCLUDE environment variable are searched.
From within the development environment, the INCLUDE environment variable is ignored. To
set the directories searched for include files (this information also applies to the LIB environment
variable.), see VC++ Directories, Projects, Options Dialog Box.
The following example shows file inclusion using angle brackets:
#include <stdio.h>
This example adds the contents of the file named STDIO.H to the source program. The angle
brackets cause the preprocessor to search the directories specified by the INCLUDE environment
variable for STDIO.H, after searching directories specified by the /I compiler option.

Example: The following example shows file inclusion using the quoted form:

#include “defs.h”
This example adds the contents of the file specified by DEFS.H to the source program. The
double quotation marks mean that the preprocessor searches the directory containing the parent
source file first.

Nesting of include files can continue up to 10 levels. Once the nested #include is processed, the
preprocessor continues to insert the enclosing include file into the original source file.

Self Assessment

Fill in the blanks:

The challenge could even be a hoax or just a hyped up minor event, said security experts. But

so has the Ministry for Information and Communication in Korea which feels Korean Web
servers could be specially vulnerable to the threat. So have European Internet security experts.

monitoring of Websites and also from tracking Internet relay chats.
