Online Test Your Knowledge..

Hi Could somebody point me in the direction of any decent online 'test your knowledge' type sites?

I'm currently working through Accelerated C++ and whilst the excercises are decent and challenging, I could do with a few more scenarios to tackle.

I am only talking beginner at the moment, just finished the chapter on loops!

Thanks,


Darren.

Project Euler I got to 128.

They are more aimed at solving mathematical problems (Project Euler). If you want some coding, algorithms and problem solving challenges and tests, try TopCoder.com
