FAQ
What is C-kata?
C-kata is an online platform to practice the C programming language through challenges of different difficulty levels with automatic solution checking.
Do I need to install anything?

Can I get a refund for coins?
Refunds are only possible if a technical issue prevented your purchase from being completed.
