Syntax

The preprocessor supports conditional compilation of parts of source file.

Shows the given error message and renders the program ill-formed, or shows the given warning message without affecting the validity of the program.

Escape sequences are used to represent certain special characters within string literals and character literals.

Changes the source code's line number and, optionally, the current file name, in the preprocessor.

Floating-point literal defines a compile-time constant whose value is specified in the source file.

Implementation defined behavior is controlled by #pragma directive.

Allows values of integer type to be used in expressions directly.

Syntax

Customizes the C++ operators for operands of user-defined types.

The preprocessor is executed at translation phase 4, before the compilation. The result of preprocessing is a single file which is then passed to the actual compiler.

The preprocessor supports text macro replacement. Function-like text macro replacement is also supported.

Includes other source file into current source file at the line immediately after the directive.
