The C/C++ Preprocessor Reference explains the preprocessor as it is implemented in Microsoft C/C++. The preprocessor performs preliminary operations on C and C++ files before they are passed to the compiler. You can use the preprocessor to conditionally compile code, insert files, specify compile-time error messages, and apply machine-specific rules to sections of code.
-
Preprocessor Directives
-
Describes directives, typically used to make source programs easy to change and easy to compile in different execution environments.
-
Preprocessor Operators
-
Discusses the four preprocessor-specific operators used in the context of the #define directive.
-
Predefined Macros
-
Discusses predefined macros as specified by ANSI and Microsoft C++.

Pragmas
-
Discusses pragmas, which offer a way for each compiler to offer machine- and operating system-specific features while retaining overall compatibility with the C and C++ languages.
