Yes, most of the book is wrong. In this example, the author probably also presented this idea in a wrong way.
But the author is correct for having the idea that "constant being written directly into the program" (by the compiler!) and "integer constants are stored somewhere in memory", they are correct and make perfect sense. Of course the integer constants and string constants are all allocated and stored somewhere in memory (or somewhere that can be mapped as memory). They are usually known the text segment and data segment.

Good enough IMHO. It is true that an array "name" is a pointer to its base address.
