Interesting programming website to improve your skills: exercism.io

They also provide a nice command-line utility to fetch new challenges (as seen in the right of my image). :thumbsup2:

That looks quite good, I've just started the Project Euler challenges. I've been looking to getting back into programming with C/C++ and wanted some motivation to do so, my book exercises aren't exactly interesting!
