I would guess that if you are comfortable with basic programming concepts such as program control structures (if, for, while, etc), what a variable is and what functions are, this would be sufficient.
Yeah, and "getting started" stuff like where to write your code and how to get it compiled and run. The problem with Accelerated C++ for beginners is that there's no hand holding on how to get started before writing your first program, so my opinion is that those who no background and mentor will simply get discouraged because they do not know what to do. However, since you got as far as asking on a forum, and you do have another book that might explain how to get started, that should not be a problem.
