title: codingbat-like site for C++
body: <p>Guys, I need to find a good site like <a href="http://codingbat.com/" rel="nofollow noreferrer">codingbat</a> to "learn again" C++. I learned it at school but then I've never used it seriously. I'm not looking for something like Project Euler because it focuses on math problems. I need something really focused on C++ principles, chacteristics and tools.</p>
