The book by Bjarne Stroustrup, it's the only textbook we're required to have for our class... anyway, I recently found out you can get the 3e of the book in PDF from MAXcode.com for free.... the thing is, they say the download is for "Big C++ One", when I was curious as to what it was, I found out it was the entire book in PDF format... so in case anyone is looking for a great reference book, check out the PDF, or better yet.... buy it!
The C++ Programming Language - 3rd Edition
(it's listed as 'Big C++ One' for some reason)
