 == Dialects ==
-There are two popular dialects, the original was K&R C, which spread with the original C [[compiler]], and [[pcc]], the portable C compiler.  Later there was a ANSI standard to the C language, and it's usually refered to as just ANSI C.
 The C language evolved continuously starting in 1972.  Some milestones:
