Does anyone know of free C++ assessment tests?
I would like to practice my C++ skils before interviews. Brainbench used to have it for free; now they want $49.99 and I think it's rip off..
Most of those "C++ questions" and pay-for-view packets are a ripoff and often a scam.
If you are interviewing at a big company, explicitly Google their name and c++ interview questions. Enough people post the interview questions online, and these companies are way too lazy to actually change this question set. Examples include Google, Bloomberg, and others.
If you want to ace interviews that ask about c++ corner cases, consider the c++ faq or the C++ faq lite (http://www.parashift.com/c++-faq-lite/). It's not questions, but it's the most valuable C++ resource IMHO.
And if you don't use C++ on a day to day basis, try to write some code and compile. I was humbled after too many years of Java to see how much of the syntax is no longer natural to me.
You might want to try My CPP Quiz as that has a set of very comprehensive C++ questions. If you can get through those easily you could consider yourself having a satisfactory understanding of basic C++.

There is plenty of algorithmic problems to solve at SPOJ. Some of them are straightforward, well known algorithms implementations (see also The Problems classifier) some are harder. The online judge service will check your code's correctness online.

I need to learn C++. Because I like the book's concept and I can already program in several other languages I thought "Accelerated C++: Practical Programming by Example" would be the best choice. However, the book is over 12 years old. Is it still a good idea to pick it up or would I be missing too many important new features of the language?
It remains one of the best books around. It's based on C++98, but C++03 is more bug fixes than anything else, and most programmers can't use anything more recent anyway. As with most languages that have been around for awhile, recent evolutions can be thought of as either fine tuning, or additional features to handle new issues (like threading).
I read some C++ books, and i recomend C++ Primer.
The way the author teaches the language is very insterestig.
Besides its a "heavy" book, you can learn more deeply the language and how to avoid errors.

I'm a C++ programmer who wants to expand his knowledge into SQL language because I'm dealing with QtSQL module and would like to understand it better.
I would like to find a gentle introduction to SQL language for a C/C++ programmer.
Can you suggest some reading or a particular tutorial?
See this question: https://stackoverflow.com/questions/31982/looking-for-a-good-book-to-learn-sql
the highest rated answer recommends 2 nice books for beginners.
Coming from C++ field doesn't make much difference in this case in my oppinion. Start from basic stuff and you'll be fine!
For a nice web tutorial you can also check this: http://www.w3schools.com/sql/default.asp
COMMENT: You should not ask for recomendations in SO (although judging by your reputation you are aware of the rules). There are already various answers for this question as it is too generic and subjective. Read some books and tutorials and come back with SQL coding questions ;-)

i need to start refine my memory so i like to practice a bit
do you know good site like : http://www.blackbeltfactory.com for java?
Here are some that looked promising on a quick perusal (and I'm adding to my own reading queue):
Wikibooks entry on Design Patterns in C++
Similar question answered responses on CodeGuru
C++ FAQ section on some design patterns
C++ headers from Head First Design Patterns to inspect
Have fun! (Sorry - don't know of any with a quiz for free - although the HFDP book likely has chapter-based ones)
Those links are a "must have" in your bookmarks:
Cplusplus Reference
C++ Reference
Cprogramming
Cplus About
IBM XL C/C++ V7.0
More C++ Idioms.
Another thousand usefull links can be found by googling. One of them will fit your taste.
You already got quite a few references so far, I just want to add this one, Data & Object Factory at http://www.dofactory.com/Patterns/Patterns.aspx.
I would say you can use java exercises....just write it in c++, its the same...
Grab http://www.amazon.com/Design-Patterns-Elements-Reusable-Object-Oriented/dp/0201633612/ref=sr_1_1?ie=UTF8&qid=1299852356&sr=8-1

I would like to learn about streams in C++. I have done some googling and searching on Amazon and have not had any success in finding a book/web resource on this topic. Any suggestions would be much appreciated! I have found some information on sites like cplusplus and forums, but I'm still still unclear about a number of issues. I would really like a clear, comprehensive resource.
One thing that I would like to do is get input for my programs from external files.
Thank you for any suggestions.
Standard C++ IOStreams and locales by Langer and Kreft is dedicated to streams (and locales, which streams use extensively), but it sounds like you want a general overview as you'd find in a general reference or introductory book.
I don't know of a book that deals with streams as its major subject. I'm sure you can find a lot of resources on the Internet, but judging their quality may be difficult. The following two books have rather good coverage of streams and might be work looking into. Of course they cover a lot more than just streams.
The C++ Programming Language by Bjarne Stroustrup
The C++ Standard Library: A Tutorial and Reference by Nicholai Josuttis

Recently a colleague asked my opinion on the use of exception specifications in C++ code, and I was able to dredge up this article by Herb Sutter: A Pragmatic Look at Exception Specifications. The article, like most by Herb Sutter, is an educational read, but the short answer is "don't do that."
In the summary, he makes reference to a poem entitled "Twas the Night Before Implementation", wherein, effectively, a standards committee bows to the demands of users to add a feature at the last minute, only to discover that while it does what was asked for, it doesn't really do what they wanted. And yes, exception specifications fit that bill. As he says, "The feature seemed like a good idea at the time, and it is just what some asked for." If that is not enough, he then visits ''export'' with similar sad results.
So the question is this: What 'feature' of C++ turns out to be broken, and should not be used, if you do not wish to experience tears. This may be prey to subjective bickering, but I hope people will cite a specific experience where the feature was deployed only to cause measurable problems. Even better would be citations of articles by leading lights like Sutter (or anyone deeply involved in the Standard) warning people off of a feature.
If you include library features as well: auto_ptr. It has its uses but it's also easy to misuse. The next C++ standard will deprecate them as well in favor of the safer and more flexible std::unique_ptr.
