I know only C++11 and C. I'm quite good with C++11, I code almost every day. The Hackathon will be the next September. I would really liek to partecipate to challenge myself and to see what can I do in a so short time.
So, is possible to partecipat knowing just C++?
I've a lot of time to brace myself, have you any rec on how to be prepared for a Hackathon?
