C++ book back cover raises questions

The back cover of C++: The Programming Language raises questions not answered by the front cover, which shows code written in JavaScript. The back cover promises 'utmost significance' and 'incredible insights' but the text is generic and could describe any textbook. Similar language is used in blurbs for other books, including Casting Handbook and Food Industry: Processes and Technologies. The author criticizes the text for lacking depth and specificity.
