Online C++ Editor

An in-browser C++ editor is paired with a sandboxed compiler backend that compiles and runs code without installing tools locally. Users provide source_code, select a standard (C++14/17/20), optionally supply input_data, and trigger execution. The system captures stdout, stderr, exit code, and resource usage, returning results in a structured format for review or sharing.\n\nConceptually, the workflow separates authoring from execution: code is stored in a temporary workspace, the selected toolchain compiles to a sandboxed binary, and input data is fed through standard input. The backend isolates each run, enforces time and memory limits, and surfaces compiler diagnostics and runtime errors. This makes it suitable for classrooms, interviews, and rapid prototyping.\n\nUnique value lies in accessibility and reproducibility: no local setup, consistent environments across users, and the ability to export code and logs for debugging, peer review, or assessment. Typical use cases include teaching snippets, interviewing candidates, pair programming, and validating algorithmic ideas before porting to a full project. Optional multi-file projects and library usage can be enabled in supported deployments. The tool emphasizes safe sandbox execution, deterministic results, and clear diagnostic details to guide learning and evaluation.
