• Programming - is the art of creating software that is written in the programming language. The programming language - this is a formal system of signs that is designed for writing programs that is understandable. This site is intended for beginners, for dummies, for beginners, for children as well as for professionals. The programming language - a system of notation for describing algorithms and data structures defined artificial formal system by means of which to express algorithms. The programming language defines a set of lexical, syntactic and semantic rules that specify the appearance of the program and the actions performed by the PC under its control. Since the creation of the first programmable machine was created more than two and a half thousand languages. Every year, their number is replenished with new ones. Some languages ​​are able to use only a small number of their own development, while others are known to millions of people.
