• Multiple users can edit the same piece of code simultaneously.
• User can compile the code by clicking ‘compile’ button. The compile result will be displayed to user.
• User can run the code by clicking ‘run’ button. The execution result will be displayed to user.
• User can browse pre-stored coding problem list.
• User can get details of a specific coding problem by clicking the problem in the list.
• User can submit the code through ‘submit’ button to submit the code to solve the chosen question. The result, including compiling, correctness and running time, will be presented.
• User’s submissions will be recorded for reference.
• User can check his progress / statistics for questions.
• Admin can manually add new problem.
