Deliberate C practice
Learn by solving, understanding, and trying again.
Build real developer skill through deliberate practice. Today, c0den offers one published C exercise, a browser editor, and local drafts. Automatic code evaluation is still in development.

Product status
What works today
“Available” means the feature exists in the current application. “Beta” means it is usable with a deliberately limited scope.
Browser code editor
AvailableWrite C code in the authenticated exercise workspace.
Local code drafts
AvailableRestore account-scoped exercise drafts stored in the current browser.
Published C exercises
BetaPractise the published C exercise while later curriculum entries remain clearly marked as planned.
Local exercise activity
BetaResume exercises opened in the current browser without treating that activity as trusted completion.
Public C exercise demo
BetaExplore the real C exercise structure without an account while evaluation remains explicitly simulated.
The current learning loop
Practise with an honest workflow

1 C exercise is published today.
Write in the browser
Use the editor for C source code without running it in the web app.
Keep a local draft
Signed-in drafts stay in the current browser and do not sync.
Preview evaluation
Explore a clearly labelled simulation of the planned evaluator.
In development
Evaluation and trusted progression
Authenticated mock submissions now persist a source snapshot and exercise queue states, but remain simulations. Compilation, trusted tests, final grading, XP, levels, and exercise unlocking still need the separate isolated evaluator and remain planned.
Evaluation preview
SimulationSee an illustrative evaluation report that does not compile, execute, or grade submitted code.
Persisted mock submissions
SimulationStore an authenticated source snapshot and exercise a deterministic queue flow without compiling, grading, XP, completion, or unlocking.
Isolated C compilation
PlannedCompile submitted C code in a separate restricted evaluator service.
Public tests
PlannedRun evaluator-backed visible tests without awarding completion.
Hidden tests
PlannedRun private evaluator tests as part of a trusted final submission.
Memory checks
PlannedInspect evaluator-run programs for supported memory-safety failures.
Trusted XP
PlannedAward persistent XP only after an evaluator-verified completion.
Exercise unlocking
PlannedUnlock later exercises from trusted prerequisite completion.
Cross-device learning sync
PlannedSynchronize drafts and learning activity between signed-in devices.
