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++.
- 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.
- C++ Language Reference
- Provides reference material for the Microsoft implementation of the C++ language.
- C Language Reference
- Provides reference material for the Microsoft implementation of the C language.
- Building a C/C++ Program
- Provides links to topics discussing compiler and linker options.
- Visual C++ Libraries
- Provides links to the various libraries provided with Visual C++, including ATL, ATL Server, MFC, OLE DB, the C run-time library, and the Standard C++ Library.
