Introduction to the language of SI ++

The content was built on the principle of a smooth transmission from the means of pure SI: at the beginning, the OOP is determined as a paradigm based on the O-Minor by messages, then the method for the usual open structure is introduced, after which it is already described about protection and its purpose, then ( Since this is now necessary) designers and destructors are introduced, etc. The so-called “Standard Library "SI ++ (also known as STL) is not mentioned in the book at all, because if you start learning C ++ with STL, there is a risk to never know the language itself. For the input-output, examples use the functions of the SI library (Printf, etc) In addition, all the "improvements", offered by the authors of the so-called "standards", are also ignored in the book.
In the fifth edition, the heading has been slightly changed, several new paragraphs were added, a number of errors detected are led and the text of the preface has been fully recovered.
