Algorithm to develop embedded C

A sample program introduces C
C is a free field language
Precedence of the operator determines the order of operation
Comments are used to document the software
Preprocessor directives are special operations that occur first
Global declarations provide modular building blocks
Declarations are the basic operations
Function declarations allow for one routine to call another
Compound statements are the more complex operations
Global variables are permanent and can be shared
Local variables are temporary and are private
Source files make it easier to maintain large projects
