Source code is hard to read
Reviewed in the United States on September 27, 2019
The source code in the book is really quite difficult to read because language keywords (for, return, etc.), types (int, float, etc.), preprocessor syntax (#define, etc) have all been printed with a very faint light gray ink.
I guess this is a misguided attempt to mimic the syntax highlighting of a programmer's code editor, but the result is that ironically the source code is much harder to read in print. (This reviewer has perfectly good eyesight by the way).
