C/C++ Preprocessor Reference

C/C++ Preprocessor Reference 

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.

In This Section

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.
