That's the book I am about halfway through right now.
I really like it, as I am still fairly new to C++. It's not hard to follow, the examples are clear and I had heard that everyone gets tripped up on pointers in C++ when they learn, but the book does a good job of explaining them.
I have seen that book recommended more than once.
That book follows a very different teaching style from Accelerated C++. In C++, the age of the book is certainly not correlated with its 'good-ness' and usefulness, unlike books for languages like Java or Python which go through major language changes more frequently. The last ratified C++ standard was C++03 (which was errata changes and minor additions to C++98), and don't forget that C++ had existed for far longer before that. Prata's 5th edition book is markedly similar to his 4th edition, which was published in 2001 or so, and the 5th edition is from 2004.
Prata's book teaches C++ in a very C-centric way (focusing on raw pointers and arrays, C-style strings first, waiting until much later to discuss C++ constructs), whereas Accelerated C++ teaches C++ constructs and styles from the start (using the standard library more like <vector> and <string>, and not even mentioning raw pointers until the tail end of the book). If you wanted to start off with C instead, I would instead recommend The C Programming Language
Not to mention that Prata's book is about 1200 pages long (I completed his book front to back way back in the day), which is about twice the length of Accelerated C++ and CPL combined. I used to recommend Prata's work more, but after reading some of the other introductory books in C++, I have shifted to recommending ones that teach with an upfront C++ focus more.
If you want a book that exists in digital form, then I don't think anything I'd recommend exists in that form (and CPL is 20 years old!)
It's A language, but what are you learning it for? Many languages exist because they have different strengths. C++ is general purpose, multi-paradigm, and while it's one of my languages of choice, it's not the language I use for everything (it has to compete with Python, Java, Scala, and even normal C).
If you want to learn C++, then learn C++. Certainly there will be cross-pollination as C++ is a superset of C and inherits much from C, but you can write a lot of C++ without having to use C-style constructs.
And, indeed, the idiomatically correct ways to do things in C and C++ are often different. C code can be (and very often is) legal C++, but that doesn't mean it's how you'd do it if you set out to write C++.
(I sort of like straight C, it's a fairly small and simple language.)
