I did not go deep enough in the book yet. However there are serious errors in Chapter 4. Several Exercises (7e, 7d and others) try to compare string literals using operators without any comments that this operation has random outcome. Answers do not mention anything about it either making student believe that there is a definite correct answer to such a comparison. This is 7th (!) edition of a very expensive text book used for 1st year C++. It should not have flops of the kind. I do not know what is coming later in more complicated areas. Otherwise the book is nicely set.
