Be careful though, this course is copy and paste the zero of the site, there are people who can take this to the "scam". Personally, I bought this book AFTER discovered [...] because I wanted to encourage its creators in their approach. I think they do a great job in written tutorials for many programming languages and software, and I find that all work deserves, let alone when it's (very) good job.
Conclusion: so I highly recommend this introductory book to C ++!
