Why pre processor is used in embedded?
What is it use?
 

Hello!

Preprocessor is a software coming before the compiler.
All the preprocessor directives are preceded with #
Examples:
#include xxxx.h
#define something some value
etc...
You may be interested in reading a book about C language (not only C, but it's the most common).
