http://en.wikipedia..../C_preprocessor
Because # is an instruction for the C pre-processor, not the compiler.

Well! It is a C-style of defining Macros and including Header files...
e.g.
#define Identifier Value
&
#include header


Also, as Salem_c mentioned, these directive are processed by the per-processor before compilation. The header files are included in the specified file and the Macros are evaluated to the value they are defined to...

Hope this Helps!
