C-kata is an online platform to practice the C programming language through challenges of different difficulty levels with automatic solution checking.

No. Everything runs in the browser: code editor, compilation, and test execution.

XP (experience points) are earned for solving challenges. As you gain XP, your grade increases: Siran (Novice) → Kyu (Apprentice) → Dan (Journeyman) → Sensei (Master).

CKC digital credits are in-platform credits used to unlock paid functionality on c-kata.com. You earn them for solving challenges or buy them directly. 1 CKC = €0.10

On the Pricing page. You can choose packages (€10, €25, €50) or a custom amount. Payments are made in EUR (Visa/Mastercard).

Your code is compiled, executed in a sandbox, and checked against test cases. Results are shown instantly.

Refunds may be granted where CKC digital credits were not delivered after successful payment, where a confirmed technical failure prevented delivery or proper use of purchased CKC digital credits, where duplicate billing or an obvious billing error occurred, or where a refund is required by applicable law. Refund requests must be submitted within 30 calendar days of the transaction by contacting [email protected] with your account email, transaction date, amount, receipt/payment reference, and a description of the issue.

CKC digital credits are normally delivered to your C-kata account immediately after successful payment. If delivery is delayed, please contact support with your account email, transaction date, amount, and payment reference.

We aim to respond to billing, delivery, and refund requests within 2 business days.

Yes, the editor works in mobile browsers, but the best experience is on desktop or laptop.

C-kata is part of a broader ecosystem. To practice C++ or C#, you need to use our dedicated platforms. Links to them are available in the top menu and in the footer. Each platform uses its own platform credits, which can only be used on the platform where they were purchased. You can learn more about features and pricing on: c-magus.com (https://c-magus.com/home) (C++) and csharpexplore.com (https://csharpexplore.com/home) (C#).

No. Your code stays private. You can share it manually if you want feedback.
