#include “file_name Reads in the source file specified by file_name.
#define identifier[replacement_string] Replaces the identifier with the replacement_string.
#undef identifier Purges the identifier previously defined by #define.
#ifdef identifier
block1
Assembles block1 if the identifier was defined before
the #ifdef statement.
[#else
#endif
block2]
Assembles block2 if it was not defined (nothing will be
assembled if there is no #else).
#ifndef identifier
block1

[#else
#endif

Assembles block2 if it was not defined (nothing will be
assembled if there is no #else.
#if expression
block1
Assembles block1 if the expression is not 0.
[#else
#endif
